Keraglas® is manufactured out of old glass. The production of keraglas® means that old materials are brought back into circulation for re-use. This preserves natural resources and combines ecological and economic interests.
Keraglas® is characterized by shape accuracy, a high level of pressure resistance, and is unobjectionable in terms of toxicity. Keraglas® has a slight gray-green or a cream-white tone, and is shaped like a perfect sphere.
