Enamelled glass is made with the use of ceramic paints whose thick coating is applied to the entire surface of glass and gives expected opacity. The glass is then subjected to tempering treatment during which the paint melts into the glass and creates a durable and indelible layer. This type of glass is most frequently used as so-called spandrel glass i.e. the elements used to cover building structures. They can be also used in the glass intended for furniture or in interior architecture.
