Pyrex® glass is a superior quality tempered borosilicate glass with excellent resistance to mechanical shocks.
Si fits perfectly at extreme temperatures, from -40 ° to + 300 °, and withstands thermal shocks up to 220 °.
All Pyrex® glass products can be used without fear from the oven to the freezer and viceversa.
Il Pyrex® glass consists from pure sand (80%), sodium carbonate (4%), alumina (2,5%) and boron (13%).
The mixture is melted in a furnace at a temperature of about 1.500 ° C, where it takes on the appearance of a transparent and very dazzling lava, which can only be observed through a protective screen.
Also in the oven, the material is “refined” to remove the CO2 bubbles it releases during melting.
