Professional gilding is a very specialised technique that takes many years to perfect.
The practice of gilding first appeared in ancient Egypt around 2500 BC, when based metals were pounded into very thin sheets and applied to various surfaces.
Gilding on glass, also known as Verre Eglomise, was developed in France in the late 1800s and is used to create a soft reflective finish on the reverse side of glass.
Reverse glass painting has three fundamental steps, line art, painting of internal areas, and background.
Cas works mostly on 6mm low iron clear toughened glass, which is heat resistant, and on other surfaces by request.
