acid etched glass
Acid etched glass is often confused with sandblasted glass as white acid looks similar, however, acid etched glass can offer many more finishes and degrees of transparency and diffusion of light.
Many pub windows and mirrors in Victorian times used a variety of these techniques in the same piece of glass. It can also take off the top coloured lay er of ‘flashed’ glass (see top, middle & bottom images) which reveals the clear base glass. A mask is used to stop the acid acting on the glass and therefore remains untouched.
This is one of the lost arts and few people are able to offer this technique today. It is also more expensive as it is much more specialised and uses very dangerous chemicals which are potentially lethal. Hydrofluoric Acid is the only acid which is corrosive to glass but unfortunately dissolves human tissue as well so strict safety precautions need to be adhered to.
