Properties of fused silicaHeraeus
Manufactured glass is a material formed when a mixture of sand soda and lime is heated to a high temperature and stays in a molten liquid state. Glass can be made from pure silica but quartz glass (also referred as quartz) has a high glass transition point at around 1200°C which makes it difficult to form into panes or bottles.
