During the tempering process, the vitrifiable or ceramic paint previously applied to the surface becomes part of the glass itself.
By vitrifiable paint we understand the fact that once the glass has been tempered the paint previously applied to the surface becomes part of the glass itself.
Becoming a single element with the glass itself, the ceramic paint is indelible and cannot be erased by mechanical “attacks” like marks, scratches etc…, and chemical “attacks” as the cleaning with particularly aggressive or acid detergents, nor does its colour change due to prolonged exposure to UV rays.
The printing lasts forever and cannot be removed.
