Any glass will take the heat of baking. The problem comes in the cooling down. Just doing it a little bit too quickly will cause it to crack. Any sudden change will do it. Even a cool breeze may be enough.
There is a possibility, depending on strength, size, if they will catch fire in the oven, etc.
Fire polisihing is used for the polishing of glass tube ends or other glass laboratory components; it is possible to use this method also for plastics.

To start a fire in a fire pit using fire glass, first ensure the fire pit is clean and has proper ventilation. Place a layer of fire glass in the bottom, followed by a base of kindling or fire starters. Light the kindling with a long-reach lighter or match, allowing the flames to spread to the fire glass. Once the fire is established, you can add more fire glass around the flames for a decorative effect.
To make fire using a magnifying glass, focus the sunlight through the magnifying glass onto a small pile of dry leaves, paper, or other flammable material. The concentrated sunlight will create enough heat to ignite the material and start a fire.
I'd have to say it's fire because if you burn(fire) sand(ground)then it turns to glass which is delicate. in other words fire turns sand into glass which is easy to break.(true fact)
No. There are other methods such as a panic bar.
glass that is capable of retaining its integrity in an opening after being exposed to fire.
Fire the clay like glass, not clay. The problem with melting glass on clay is the coefficient is different. Glass will craze, (crackle) on the clay. If you want the glass to stay on the clay use high fire clay and fire it to bisque first. The second firing with the glass on it should be fired on a schedule that is suitable for the glass. You can not simply fire the glass up to it's melting temperature then allow it to cool without controlling the cooling rate. You may want the rate to be 60ºF/hour to cool depending on the type of glass you are using.
no its a rare glass
Mix void and glass. Void+glass=light bulb
I will break the glass only if there is a fire emergency, as indicated in case of emergency procedures.
