All You Want to Know About Foam Glass

Contains 350 million inert air cells per cum.
Hence it floats in water and it can be cut easily like wood.
A light, opaque, black, cellular glass made by adding powdered carbon to crushed glass and firing the mixture.
Fire proof, rigid and an excellent heat insulator.
Good thermal and acoustic insulator.
Also known as Cellular Glass.
It is lightweight and has fine, watertight pores that make it an exceptional barrier against moisture, humidity and debris.

Thickness varying from 30mm to 150mm

Prepared in the form of rectangular blocks
Foamed glass is manufactured using a process that traps gas bubbles in the glass, creating an expanded material with a spongy consistency.

Using industrial glass crusher, first clean and crush recycled glass material.
Use enough glass to fill the glass furnace to capacity for time and cost efficiency.
Use glass that has a similar expansion coefficient for best results. The temperatures at which the glass melts and re-solidifies.
Mix crushed glass with powdered cullet that adds strength to the glass and with a carbon based material such as coal powder.
The carbon reacts with the glass to create carbon dioxide, which develop a foam consistency with a volume approximately 15 times that of the original crushed glass.
Place the crushed glass mixture on heat tolerant kiln forms with an anti sticking agent.
Load the kiln forms onto the roller conveyor to a high temperature tunnel furnace.
The glass should be heated to 1,000 to 1,300 degrees Celsius.
Slowly cool or anneal the foamed glass.
Gases allowing the glass to expand while heating and then stabilize during cooling.
The finished product will be pumice stone.
