- Overlay Glass - Overlay glass is coloured glass that has been created by sandwiching two or more layers of different coloured glass together. The layers are fused together through a process of heating and melting in a glass furnace, and the resulting glass has a unique colour and depth that is not found in single-layered glasses.
The technique of overlaying glass has been used for centuries, and was particularly popular in the Venetian glass industry during the Renaissance. Different colours of glass were layered to create intricate designs, and then the layers were carved and etched to create intricate patterns and details.
