Verre; Glass

Glasses can be described as non-crystalline liquids used at temperatures where their very high viscosity makes them comparable to solids. Glass objects are shaped at high temperatures in liquid form before being cooled, enabling them to be used.

Ceramic; Céramique

Ceramics are polycrystalline objects composed of grains separated by grain boundaries, produced by ceramic technology. Ceramic technology consists in shaping a powdery material at room temperature and giving it its definitive properties during a high-temperature...
