Coffee Pot-AD103
Details
Pyrolitic glass is glass used in ovens with pyrolitic function. This characteristics of this glass is that it is more resistant thermal shocks in comparison with normal glasses. At the moment borosilicate glass is used as pyrolitic glass.
Borosilicate glass is a type of glass of which the main ingredients for the formation of glass are silica and boron axide.
