Manufacture

From glass to cellular glass

To make cellular glass, the used glass must first be ground. The glass powder is then baked. This is achieved with 2% pure mineral "baking powder" in a furnace at approximately 950 degrees.

During this process, the mass of glass foams and eventually leaves the oven as cellular glass. During rapid cooling, the MISAPOR breaks up into gravel size pieces. The finished "MISAPOR stones" are made of 98% glass, 2% minerals and a large amount of trapped air. However, it is precisely this air that is ultimately responsible for the outstanding properties of the new material: thermal insulation and lightweight.
