We have been playing around in our glass & finishing studio with chipped glass. Glue is applied to glass and a specific application of the right temperature causes the glue to contract and chip off pieces of the glass.
This creates a wonderful effect of an etched type glass in a feathered effect. It is lovely to use on its own for a finish application, but becomes something quite special once back-painted and/or gilded. The finished product is quite random in the way the glass in chipped, thus not one the same. However just certain areas can be chipped by applying the glue to those areas, to create a more controlled effect.
We are in the process of using this method as application to a dressing table and we cannot wait to see the result.
