Flashcards
What is glass?
What is glass?
Glass is a solid material made primarily from melted sand, or silicon dioxide, that cools and hardens into a transparent substance.
How is glass made?
How is glass made?
The process of creating glass involves heating sand to extremely high temperatures, over 3,000 degrees Fahrenheit, causing it to melt. This molten glass can then be shaped and molded into various products.
Common ingredients in glass?
Common ingredients in glass?
Soda ash is added to melt sand quicker, saving energy and production costs. Limestone strengthens the glass, resulting in a more durable product.

Study Notes
What is Glass?
- Glass is made from sand, specifically silicon dioxide, which has a crystalline structure
- Sand needs extremely high temperatures (over 3,000°F) to melt, unlike sugar (which melts at around 300°F)
- Molten sand, once cooled, can be shaped into various forms
- Common glass contains recycled glass, soda ash (to melt faster), and limestone (to strengthen)
How is Glass Made?
- The common glass type is called soda-lime-silica glass due to the added ingredients
- Glass is an amorphous solid, meaning it's solid but retains some liquid properties
- Unlike crystalline solids, amorphous solids lack a structured arrangement of atoms
- Molten glass can be poured onto liquid metal (like tin) for flat sheets (plate glass)
- It can be poured into molds for various shapes (drinking glasses, jars)
- Glass can be hand-blown into diverse ornate shapes
Different Types of Glass
- Artists can use frit (broken glass) to decorate or add texture. Colored frit is often employed
- Special glass types (e.g., oven-proof, crystal, bulletproof) are made with added components
- Colored/tinted glass is achieved by adding various metals (e.g., iron, chromium)
- Glass blowing creates intricate shapes using a long tube and molten glass
- Sugar imitates glass in appearance, but not in strength during breakage
