A glass object can look effortless precisely because so much work has disappeared into it. The rim is even, the colour sits in a deliberate layer, and the cut surface catches light as you move. This guide teaches 100 glassmaking vocabulary words in English so you can follow a museum explanation, distinguish processes and describe an object with more precision than “shiny crystal”.
Czechia provides a rich setting through its glass and jewellery collections, workshops and living craft knowledge. Handmade glass production is recognised by UNESCO through a shared inscription involving Czechia and five other countries. That shared context matters: Czech glassmaking has particular histories and makers, while the craft itself connects people across borders.
Start with the object, then trace back to the process the record actually names. Use a group of ten words, draw a labelled sketch and write a short explanation. “Top 100” is a curated learning selection, not a statistical ranking. The entries are mainly general English technical terms contextualised through Czechia; they teach observation and communication, not instructions for operating hot-glass equipment.
Choose what you want to understand about the glass
Move from material to process, from process to form, or from an object label to a clear description.
What does “handmade crystal” actually tell you?
Imagine a label saying only “handmade crystal”. Can you identify the maker, composition, forming process, decoration and place of manufacture? Not reliably. The phrase may prompt good questions, but it does not answer every one. Begin by separating the material, the way it was formed and the way its surface was finished.
If you cannot distinguish a blowpipe from a punty, start with tools and hot working. If you use transparent and translucent as synonyms, begin with colour and light. If you can describe the object but immediately assign it to a famous workshop, begin with design, attribution and records.
Students can annotate a sketch with parts and process clues. Parents can ask which detail is visible and which is documented. Teachers can supply a revised label and ask for a revised caption. The aim is to make each new word do useful work for a reader, rather than to bury a simple description beneath technical nouns.

Glass names a material, while many familiar labels describe composition, form or marketing categories. Keep their scopes distinct.
| No. | Word or term | Meaning and usage | Natural collocation | Original example |
|---|---|---|---|---|
| 1 | glass | A usually non-crystalline material used for vessels, windows, art and many other purposes. | glass object | The learner describes the glass before assuming a particular composition. |
| 2 | silica | Silicon dioxide, a major ingredient in many common glasses. | silica content | The technical record discusses silica without treating it as the only ingredient. |
| 3 | batch | The prepared mixture of raw materials used to make glass. | glass batch | The museum diagram separates the batch from the finished object. |
| 4 | cullet | Broken or waste glass used as material in glass production. | recycled cullet | The caption identifies cullet without inventing a recycling percentage. |
| 5 | flux | A substance that helps lower the temperature needed for a process such as glass formation. | glassmaking flux | The educator explains flux as a material role, not a colour. |
| 6 | colourant | A substance used to produce colour in a material. | glass colourant | The record names a colourant that the photograph cannot identify by itself. |
| 7 | soda-lime glass | A common glass family based principally on silica, soda and lime components. | soda-lime composition | The diagram uses soda-lime glass as one example rather than every possible glass. |
| 8 | borosilicate glass | A glass family containing significant boron oxide with silica. | borosilicate vessel | The catalogue identifies borosilicate glass without the learner guessing from shape. |
| 9 | lead glass | Glass containing lead oxide as a significant component. | lead-glass composition | The source specifies lead glass, so the caption preserves that material identification. |
| 10 | crystal | A glass trade term for particular high-clarity or formulated glass; usage and standards vary. | crystal glassware | The learner asks what crystal means in this specific product record. |
Crystal glass is not the same material as naturally crystalline quartz, often called rock crystal. Do not infer lead content from sparkle or from the single word crystal. Composition claims need the relevant record, specification or applicable standard.
These terms help you understand a demonstration’s explanation. They are concepts, not a firing schedule or a guide to safe equipment use.
| No. | Word or term | Meaning and usage | Natural collocation | Original example |
|---|---|---|---|---|
| 11 | molten | In a melted state. | molten glass | The video identifies molten glass before the forming sequence begins. |
| 12 | viscosity | Resistance to flow; it changes with material and conditions. | glass viscosity | The educator links viscosity with the way softened glass moves. |
| 13 | softening | Becoming less rigid and more able to deform under suitable conditions. | glass softening | The diagram distinguishes softening from a finished object's room-temperature appearance. |
| 14 | thermal | Relating to heat or temperature. | thermal behaviour | The explanation connects thermal behaviour with the process being discussed. |
| 15 | expansion | An increase in size or volume under specified conditions. | thermal expansion | The chart describes expansion without assuming identical behaviour for every glass. |
| 16 | compatibility | Suitability of materials to work together under the relevant conditions. | glass compatibility | The demonstration names compatibility as a technical issue requiring evidence. |
| 17 | annealing | Controlled cooling of glass to reduce internal stress. | glass annealing | The learner distinguishes annealing from leaving an object to cool unchecked. |
| 18 | strain | Deformation associated with forces or stress; in glass, often discussed with residual stress. | strain pattern | The educator explains the strain pattern shown by a specialist instrument. |
| 19 | thermal shock | Stress caused by a rapid or uneven temperature change, potentially causing fracture. | thermal-shock resistance | The record discusses thermal shock under stated conditions rather than a home test. |
| 20 | fracture | A break or crack through a material. | glass fracture | The condition report records a fracture without calling it engraved decoration. |
Annealing is not hardening, and a beautifully formed object is not necessarily ready as soon as it looks solid. The process explanation should preserve the role of controlled cooling. Do not turn a vocabulary list into a temperature recipe.

WORD GROUP 3 OF 10
21–30. Name tools without treating every tool as interchangeable
A tool’s shape may suggest its purpose, but reliable identification comes from the demonstration or record you are studying.
| No. | Word or term | Meaning and usage | Natural collocation | Original example |
|---|---|---|---|---|
| 21 | furnace | High-temperature equipment used for processes such as melting glass. | glass furnace | The museum film identifies the furnace before showing the workbench. |
| 22 | crucible | A heat-resistant vessel holding material during high-temperature processing. | melting crucible | The diagram places the crucible inside the relevant heating equipment. |
| 23 | blowpipe | A hollow tube used in glassblowing. | glassblowing blowpipe | The learner notes that the blowpipe allows air into the developing form. |
| 24 | punty | A rod used to hold and support a glass object during further work; also pontil. | punty rod | The diagram distinguishes the punty from the hollow blowpipe. |
| 25 | marver | A flat working surface used to shape hot glass by rolling; also the related verb. | steel marver | The demonstrator identifies the marver rather than the learner calling it a mould. |
| 26 | jacks | A glassworker's paired-blade tool used for shaping. | glassblowing jacks | The caption labels jacks without confusing them with ordinary scissors. |
| 27 | shears | A cutting tool with two blades; specialised forms are used in glassworking. | glassworking shears | The film credits the shears' particular use in this demonstration. |
| 28 | mould | A shaped form that gives material an intended outline; mold in American English. | glass mould | The object record identifies a mould used for the repeated form. |
| 29 | bench | The glassworker's working station, often with supports for tools or rods. | glassworker's bench | The photograph shows the bench as part of a coordinated workspace. |
| 30 | kiln | A controlled heating chamber used for processes such as firing and annealing. | glass kiln | The learner identifies the kiln without assigning every heating task to it. |
Punty and pontil are related names, but a pontil mark is the trace associated with attachment, not the rod itself. A mark can help ask a process question; it does not independently identify a maker, date or place.

These words describe broad process differences. A skilled demonstration may combine several actions in one object.
| No. | Word or term | Meaning and usage | Natural collocation | Original example |
|---|---|---|---|---|
| 31 | gather | A quantity of hot glass collected for working; also the act of collecting it. | glass gather | The learner tracks the gather before it becomes a recognisable vessel. |
| 32 | glassblowing | Forming glass using air introduced into softened glass. | freehand glassblowing | The record names glassblowing rather than the caption inferring it from roundness. |
| 33 | free-blown | Formed by blowing without a mould defining the main shape. | free-blown vessel | The catalogue describes a free-blown vessel with separately documented decoration. |
| 34 | mould-blown | Shaped by blowing glass into a mould. | mould-blown bottle | The learner distinguishes mould-blown from pressed glass in the comparison. |
| 35 | parison | A partly inflated glass form still being developed. | inflated parison | The film pauses at the parison so the class can describe its outline. |
| 36 | rotation | Turning around an axis. | continuous rotation | The demonstration makes rotation visible without prescribing a technique to copy. |
| 37 | reheating | Heating material again during a process. | glass reheating | The timeline places reheating between two forming stages in this example. |
| 38 | trailing | Applying a thread of softened glass to another glass surface. | decorative trailing | The catalogue identifies trailing around the vessel's body. |
| 39 | casing | Adding a layer of glass over another layer or body. | coloured casing | The explanation distinguishes casing from paint applied to the outside. |
| 40 | pressing | Forming softened glass in a mould through applied mechanical pressure. | glass pressing | The learner compares pressing with the use of air in blowing. |
A seam-like line can prompt a question about mould use, but photographs and later finishing may complicate identification. Prefer the record’s process description. “Looks handmade” is an impression, not a complete technical account.

Glass can be shaped in different ways. These process names prevent every made object from being described as blown.
| No. | Word or term | Meaning and usage | Natural collocation | Original example |
|---|---|---|---|---|
| 41 | casting | Forming an object by placing glass into or within a mould and allowing it to take shape. | glass casting | The record identifies casting rather than the caption calling every hollow form blown. |
| 42 | fusing | Joining pieces of glass by heating them until their surfaces unite. | kiln fusing | The educator distinguishes fusing from joining separate pieces with adhesive. |
| 43 | slumping | Heating glass so it bends or settles under gravity into a form. | glass slumping | The demonstration describes slumping as a change of shape rather than colour. |
| 44 | flameworking | Shaping glass with the local heat of a flame. | glass flameworking | The film names flameworking and shows a different setup from furnace work. |
| 45 | beadmaking | Making beads through a specified material and forming process. | glass beadmaking | The museum account places beadmaking within a wider jewellery story. |
| 46 | rod | A long solid length of material; here, glass used in forming. | glass rod | The learner distinguishes the solid rod from a hollow tube. |
| 47 | tube | A hollow elongated form or length of material. | glass tube | The diagram labels the tube's hollow interior explicitly. |
| 48 | frit | Crushed or granulated glass used in glassworking. | coloured frit | The sample card identifies frit without giving a processing recipe. |
| 49 | mandrel | A rod-like support around which material may be shaped. | bead mandrel | The educator labels the mandrel in the beadmaking illustration. |
| 50 | release agent | A material used to help separate a formed object from its support or mould. | mould release agent | The process record mentions a release agent without inviting unsupervised use. |
These descriptions are for reading and comparison. Hot glass, specialised equipment, dust and some surface-treatment materials need trained practice and appropriate controls. For this learning activity, a museum film and a paper diagram supply all the evidence you need.

Cold working changes glass after forming without relying on hot-form shaping. Related decorative processes may involve subsequent firing, so identify the actual sequence.
| No. | Word or term | Meaning and usage | Natural collocation | Original example |
|---|---|---|---|---|
| 51 | cold working | Shaping or decorating glass when it is cold, using processes such as cutting or engraving. | glass cold working | The guide distinguishes cold working from the earlier hot-forming stages. |
| 52 | grinding | Removing material through abrasive contact to shape or finish a surface. | glass grinding | The condition record distinguishes grinding from accidental abrasion. |
| 53 | cutting | Removing material to create shaped grooves, facets or other defined features. | decorative cutting | The catalogue names cutting as decoration rather than a break in the object. |
| 54 | engraving | Incising a design into a surface with suitable tools or techniques. | wheel engraving | The learner describes engraving as a process, not a printed image. |
| 55 | polishing | Finishing a surface to increase smoothness or gloss. | surface polishing | The demonstration distinguishes polishing from creating the original form. |
| 56 | facet | A deliberately formed flat face on an object or surface. | cut facet | A cut facet changes its reflection as the observer moves. |
| 57 | etching | Altering a surface through a chemical process; not the same as mechanical engraving. | etched decoration | The record identifies etching without the learner inventing a chemical recipe. |
| 58 | sandblasting | Using an abrasive stream to alter or texture a surface. | sandblasted surface | The label describes sandblasting rather than ordinary wear. |
| 59 | enamelling | Applying glass-based coloured decoration and fixing it through firing. | enamelled decoration | The caption distinguishes enamelling from unfired paint. |
| 60 | gilding | Applying gold or a gold-bearing decorative layer to a surface. | gilded rim | The catalogue identifies gilding on the rim rather than solid gold construction. |
Engraved, etched and painted are not interchangeable descriptions. A matte appearance alone may not distinguish them. If the record only says decorated, preserve that broad wording until you have evidence for a more specific process.

These words are useful when you can see the object but do not have a complete technical record. Observation can be precise without becoming a chemical analysis.
| No. | Word or term | Meaning and usage | Natural collocation | Original example |
|---|---|---|---|---|
| 61 | transparent | Allowing light through with objects beyond visible relatively clearly. | transparent glass | The transparent body lets the learner see a shape behind the vessel. |
| 62 | translucent | Allowing light through while scattering it so objects beyond are not clearly seen. | translucent panel | The translucent panel glows without giving a clear view through it. |
| 63 | opaque | Not allowing visible light through in the observed conditions. | opaque glass | The learner describes opaque glass without assuming a particular colourant. |
| 64 | colourless | Without a noticeable hue; not the same as transparent in every context. | colourless vessel | The caption calls the vessel colourless rather than white. |
| 65 | reflection | Light returning from a surface. | surface reflection | The bright reflection moves when the observer changes position. |
| 66 | refraction | A change in light's direction as it passes between media under relevant conditions. | light refraction | The drawing uses refraction to explain an apparently displaced line. |
| 67 | iridescence | A shifting play of colour that changes with viewing or illumination. | surface iridescence | The record distinguishes intended iridescence from a guessed material composition. |
| 68 | lustre | The appearance of sheen or reflected brightness at a surface. | metallic lustre | The learner describes lustre without assuming the whole object is metal. |
| 69 | bubble | A gas-filled cavity within glass or another material. | trapped bubble | The caption records a bubble without automatically calling it a flaw. |
| 70 | striations | Lines or streak-like features within or on a material. | visible striations | The observation notes striations while leaving their cause to the technical record. |
Clear is convenient but ambiguous: it may mean transparent, colourless or simply easy to see. Choose the specific word your observation supports. A colourless object can still scatter light, and a coloured object can be transparent.

A reader needs to know where a feature sits. Use part names before adding an elaborate account of style.
| No. | Word or term | Meaning and usage | Natural collocation | Original example |
|---|---|---|---|---|
| 71 | vessel | A container, such as a bowl or bottle. | glass vessel | The catalogue identifies a vessel without supplying an unsupported former use. |
| 72 | vase | A vessel often intended for displaying flowers or for decoration. | decorative vase | The caption calls it a vase because the collection record does. |
| 73 | goblet | A drinking vessel with a bowl supported by a stem and foot. | stemmed goblet | The learner distinguishes a goblet from a stemless tumbler. |
| 74 | tumbler | A drinking vessel without a stem or handle, usually with a flat base. | glass tumbler | The practice sketch shows a tumbler beside the stemmed form. |
| 75 | bead | A small object, commonly pierced for threading or attachment. | glass bead | The learner connects the bead's hole with its possible method of use. |
| 76 | pendant | An ornament intended to hang from a chain, cord or other support. | glass pendant | The catalogue identifies a pendant rather than a detached vessel part. |
| 77 | rim | The upper edge of an open vessel. | polished rim | The close photograph shows the rim but not the object's entire profile. |
| 78 | body | The main central part of a vessel or other object. | vessel body | The engraving extends across the body below the neck. |
| 79 | stem | The narrow supporting part between a vessel's bowl and foot. | slender stem | The learner locates the stem before describing its proportions. |
| 80 | foot | The supporting lower part of a vessel or object. | circular foot | The foot is visible beneath the stem in the labelled drawing. |
A beautiful form need not have an obvious practical function. Some glass is designed as sculpture or display work. Use the recorded object name and discuss a proposed use as a proposal when the evidence does not settle it.

These words describe decisions and collaboration. They help explain why a finished object involves more than one dramatic moment at a furnace.
| No. | Word or term | Meaning and usage | Natural collocation | Original example |
|---|---|---|---|---|
| 81 | design | The planning and organisation of an object's form and other properties. | glass design | The design connects the vessel's proportions with its intended presentation. |
| 82 | sketch | A preliminary drawing used to explore or communicate an idea. | design sketch | The sketch proposes a form that the prototype later changes. |
| 83 | prototype | A trial version used to explore or test a proposed design. | glass prototype | The prototype is evidence of development, not proof of a finished production run. |
| 84 | profile | The outline of an object viewed from a particular side. | vessel profile | The learner compares the profile in the drawing with the finished object. |
| 85 | proportion | The relative size of parts within a whole. | balanced proportion | The review explains proportion by comparing the stem with the bowl. |
| 86 | symmetry | Correspondence of parts under a specified reflection or other transformation. | rotational symmetry | The sketch marks the axis used to discuss symmetry. |
| 87 | craftsmanship | Skilled judgement and execution involved in making. | glass craftsmanship | The account explains craftsmanship through documented decisions rather than empty praise. |
| 88 | teamwork | Coordinated contributions from several people. | workshop teamwork | The film credits teamwork instead of presenting the object as one isolated action. |
| 89 | apprenticeship | Sustained learning of skilled work through guided practice. | craft apprenticeship | The learner distinguishes an apprenticeship from watching a short demonstration. |
| 90 | quality control | Checks that work meets defined requirements. | production quality control | The report specifies the requirement before describing quality control. |
A prototype, a unique studio work and a production object have different purposes. Do not assume that handmaking excludes a mould, a team or repeated designs. Name the actual contributions and processes when the record supplies them.

The final group turns technical vocabulary into a trustworthy description. An uncertain attribution should remain uncertain after it enters your paragraph.
| No. | Word or term | Meaning and usage | Natural collocation | Original example |
|---|---|---|---|---|
| 91 | attribution | An identification of a maker, origin or association, with its stated certainty. | maker attribution | The caption preserves the museum's qualified attribution rather than naming a maker confidently. |
| 92 | provenance | The documented history of an object's ownership or custody. | collection provenance | The learner separates provenance from the object's manufacturing technique. |
| 93 | inscription | Words or marks written, cut or otherwise placed on an object. | engraved inscription | The record transcribes an inscription without the learner inventing its translation. |
| 94 | signature | A maker's or other named person's identifying mark, requiring contextual interpretation. | artist signature | The signature is recorded without treating it alone as complete authentication. |
| 95 | accession number | An identifier associated with an object acquired into a collection. | museum accession number | The caption includes the accession number so its record can be found. |
| 96 | condition | The present physical state of an object. | condition report | The condition report distinguishes a later chip from intended decoration. |
| 97 | chip | A small piece broken away, or the resulting area of loss. | rim chip | The learner records the chip without touching or testing the object. |
| 98 | restoration | Work intended to recover or reinstate aspects of an object's appearance or function. | documented restoration | The caption notes restoration when the collection record identifies it. |
| 99 | conservation | Professional care intended to preserve an object and its evidence. | glass conservation | The museum's conservation record explains care rather than manufacturing origin. |
| 100 | interpretation | An explanation of significance or meaning based on evidence and reasoning. | museum interpretation | The learner attributes the interpretation to its source and states an open question. |
An inscription, a brand name and a geographical style label are different kinds of evidence. A record’s careful uncertainty is information worth preserving. It is better to write “attributed to” accurately than to produce a more confident but less truthful sentence.

Worked example: one imagined vase, three different kinds of claim
Consider a fictional classroom label: “Vase. Made in Czechia. Mould-blown glass with engraved decoration. Maker not recorded.” The accompanying drawing shows a coloured body, a narrow neck and several flat-looking highlights. This is an invented exercise, not an object from a real collection.
A weak caption says, “A famous Bohemian artist hand-cut this solid crystal vase.” Almost every important part has outrun the record. The maker is not recorded; the material is called glass; the forming method is mould-blowing; and engraved decoration does not establish that every bright area is a cut facet.
A stronger caption says, “The label identifies this vase as made in Czechia from mould-blown glass with engraved decoration. The drawing shows a narrow neck above a coloured body. The maker is not recorded.” It is shorter, easier to check and more informative about the actual object.
Now change the label to “pressed glass”. The forming explanation must change even if the drawing looks similar. Change it again to “attributed to a Czech workshop”. Origin and maker attribution are now qualified rather than settled. The exercise shows why an elegant appearance cannot do the work of a technical record.
To extend the task, write a question for a museum educator: “Does the record identify how the surface was finished, and are the bright areas facets or reflections in this image?” The question distinguishes the object from the conditions of its photograph. That is an excellent use of new vocabulary: it makes the missing information clear.
Czech glassmaking is a field of people and different practices
The State Museum of Glass and Jewellery in Jablonec nad Nisou presents glass alongside jewellery and related collections. Its institutional material offers a wider entry into the subject than one familiar image of a cut drinking glass. Beads, objects, design and different forms of decorative work invite different questions.
UNESCO’s handmade-glass inscription is shared by Czechia, Finland, France, Germany, Hungary and Spain. Use that international context accurately. The inscription recognises knowledge, craft and skills; it does not certify every object sold with a heritage label, nor does it make the entire craft exclusive to one country.
Bohemian is a historical and regional term that appears in glass records, while Czechia is a present country name. They should not be used as an automatic maker attribution. A museum record may identify a region, a workshop, a designer and a date with different levels of certainty.
The published Czechia learning guide connects glassmaking with individual skill and teamwork. For vocabulary learning, that is a useful direction: ask which people, tools and stages contribute to the documented object. A country theme can make the enquiry vivid while leaving room for varied regional histories and contemporary practices.
An original museum conversation: let a precise question do the work
Learner: “Is every bubble a mistake?” Educator: “Not necessarily. Some objects deliberately incorporate bubbles; in other cases a record may discuss them as a feature or defect. What does this record say?” Learner: “It only names the material and maker.” Educator: “Then describe what you can see and leave the production judgement open.” This is an invented teaching exchange.
Learner: “Could I write transparent instead of clear?” Educator: “If you mean that you can see objects through it, that is more precise. If you mean it has no noticeable colour, use colourless.” The vocabulary improves because the question separates two properties that the everyday adjective had bundled together.
Try the exchange with a partner using a permitted collection photograph. One person makes an observation; the other asks whether it establishes material, process, attribution or appearance. Then reverse roles. The activity should make you more curious about the object rather than afraid to describe it.
Practice: describe the object without inventing its manufacture
A. A coloured vessel allows objects behind it to be seen clearly. Choose transparent, colourless or opaque, and explain which property the answer identifies.
B. Distinguish a blowpipe from a punty. Which term names a hollow tube used for introducing air?
C. A label says mould-blown and engraved. Does it establish that the object was pressed, painted or made by a named artist?
D. Rewrite: “The sparkling object must contain lead and be from a famous Czech workshop.” Preserve one observation and request the missing evidence.
E. A prototype resembles a finished object. What additional information would establish that a production run was completed?
F. Write a 90-word caption using rim, body, process and attribution language. Use either a real documented object or a clearly labelled fictional one.
Answers and explanations
A. Transparent describes the clear passage of a view through the material. The object can be transparent while coloured, so colourless would answer a different question.
B. A blowpipe is hollow and is used in blowing. A punty supports the object during further work; it is not simply another name for the blowpipe.
C. No. It establishes the processes named by the label. It does not supply a different forming method, a painted surface or a maker attribution.
D. For example: “The surface produces bright reflections. Composition and workshop attribution require a reliable record.” Other accurate observations and questions are possible.
E. A production record or equivalent documented evidence is needed. The prototype alone establishes a development object, not completed manufacture or sales.
F. A strong caption locates visible features, preserves the source’s process names and keeps unknown or qualified information explicit. Additional impressive words are unnecessary if they add no useful distinction.
Make the vocabulary work in a new object description
Start with glass, mould, blowpipe, punty, annealing, engraving, transparent, translucent, rim and attribution. Retrieve them through a labelled sketch, then explain three contrasts: transparent versus translucent, blowing versus pressing, and visible appearance versus documented process.
On another day, use a different object type, perhaps a bead instead of a vase. Keep the relevant terms and replace the ones that no longer fit. Write for a visitor who has never seen the object, then for a classmate comparing technical records. The audience changes what needs explanation.
Parents can ask a learner to show the evidence behind one adjective. Teachers can remove the material field from a practice record and check whether learners leave it unknown. A later independent caption should become more precise about uncertainty as well as richer in vocabulary.
The same habits support museum work, design communication, manufacturing documentation, translation and product writing. Each field has its own standards and responsibilities. This guide offers a clear language starting point; practical glassworking and formal material claims require appropriate expertise and evidence.
Frequently asked questions
Is all Czech glass crystal?
No. Czech glassmaking includes varied materials, processes and object types. Use the specific record rather than turning a country label into a composition claim.
Does crystal always mean lead glass?
No. The trade term and applicable categories need context. Do not infer lead content from a name or sparkle; check the actual specification.
Is handmade glass always free-blown?
No. Hand production can use moulds, tools and teamwork. Free-blown names a more specific forming distinction.
Are engraving and etching interchangeable?
No. Engraving involves incising a surface through tools or related mechanical techniques; etching uses a chemical process. Check the named method.
Can I learn these words without visiting a workshop?
Yes. Authoritative collection records, permitted photographs and museum films support the central reading and writing tasks. You do not need to handle equipment or test an object.
