What it is Filled
Glass is an amorphous solid that exhibits a glass transition when heated towards the liquid state, including silicate and non-silicate compositions such as phosphate glasses; examples include soda-lime, borosilicate, lead, phosphate and fused quartz glasses, and natural glasses such as obsidian and fulgurite. Glasses serve building, packaging, optical, fibre and artistic uses, while transparency and suitability for recycling depend on composition, condition and available recycling systems.
Why it exists Filled
Let an agent explain glass types and properties, support selection for building, packaging and optical uses, describe making and recycling, and address safety.
Distinguishing features Filled
- Glass is an amorphous solid.
- Glass is typically silica-based.
- Transparency depends on composition and condition.
- Glass is typically brittle, and its suitability for recycling depends on composition, condition and available recycling systems.
What robots and AI may and may not do Filled
Must not
- Leave broken glass where people or animals can be cut.
- Present ordinary glass as safety glass where safety glass is required.
- Use glass not rated for heat or pressure in such conditions.
- Misrepresent the age or maker of glass art in a sale.
Only with a human decision
- Approving glass for structural or safety use.
May
- Explain glass types, properties and uses.
- Report broken or cracked glass in places it monitors.
- Advise on recycling glass according to local rules.
Moral aspects Filled
- Broken glass injures people, especially children.
- Glass art and historic windows are heritage.
Who is affected
- People nearby
- Glass workers
- Collectors
Owners Filled
Steward
The owner of the item or building.

What else AI and robots need to interact with it Filled
Identity and identifiers required Filled
- Vercy registry: vr.tr.glass
- Wikidata: Q11469 (https://www.wikidata.org/wiki/Q11469)
Direct properties required Filled
- Density: kg/m3 - Density is measured from mass and volume and varies with glass composition.
- Glass transition temperature: degrees Celsius - The transition is characterised by calorimetry or thermal expansion measurements under a stated heating rate.
- Refractive index: dimensionless - Refractive index is measured optically at a specified wavelength and temperature.
- Linear thermal expansion coefficient: 1/K - Thermal expansion is measured from dimensional change over a specified temperature interval.
Recognition required Filled
- Glass is an amorphous solid whose transparency depends on composition and condition.
- Glass is brittle and can be sharp when broken.
- Clear plastics are lighter and softer.
- Transparent or coloured hard material, brittle, with smooth surfaces.
Capabilities and actions required Filled
- explain glass composition and types
- select glass for an application
- describe manufacturing and recycling
- give safety guidance
Hazards and failure modes required Filled
- Cuts from breakage
- Thermal shock cracking
- Spontaneous breakage of tempered glass
Standards and interfaces required Filled
- Building codes for glazing and safety glass
- Food contact rules for glass containers
- Recycling and packaging regulations
Context of use required Filled
- Transparent and durable material for many uses.
- soda-lime glass
- borosilicate glass
- lead and optical glass
- phosphate and specialty glass
- fused quartz and natural glass
