How is safety glass made?
Thermal quenching is obtained by passing the glass in an oven at around 600°C followed by sudden and rapid cooling, whereas chemical tempering makes it possible to obtain similar effects with a different process.
(Dante Alighieri) Glass is made up of natural elements, the main one being quartz sand. Soda reduces the melting point of quartz sand. Limestone gives glass hardness, shine and solidity. But at Vetropack, the crucial role is played by recovered used glass.
Recipe for high quality, sustainably produced glass Glass is made from natural elements, the main one being quartz sand. Soda reduces the melting point of quartz sand. The oven heats the mixture to 1580 degrees Celsius. Used glass and primary raw materials melt.
Although the raw material used may vary, the general glass manufacturing process remains the same. Bring silica sand. Also called quartz sand, silica sand is the basic ingredient in the manufacture of glass. Glass that does not contain iron impurities is used to make transparent glass objects.
The basic component in the manufacture of glass is the sand or, more precisely, the silica (SiO 2) it contains. The problem is that silica has the annoying tendency to melt only at very high temperatures, above 1,700°C. So, to facilitate the process, we add fluxes such as soda, potash or lime.
