MELTING
The raw materials, which consist mainly of silica sand, limestone, kaolin, and dolomite, undergo precise weighing and thorough mixing to create a consistent ‘batch’ before being introduced into the furnace.
The manufacture of glass is carried out in a special furnace at about 1550°C/2822°F (E-Glass) using finely ground raw materials from carefully selected quarries. The glass leaves the furnace at a very high temperature and is used to feed bushings (blocks pierced with hundreds of holes) of platinum alloy. Most Vetrotex products are based on E-Glass continuous fibers, we also produce C-Glass staple fibers.
