how the glass artist http://www.heikebrachlow.com is shaping the transparent color.
“Colour in transparent glass is different to colour in most other materials: brighter, more changeable, and affected by the environment. This is due to the optical properties of glass: transmission, reflection and refraction of light. It is therefore not surprising that many glass artists explore colour within their work. However, artists generally buy their coloured and clear glass, and are therefore restricted to a finite range of hues available from manufacturers. Anybody working with solid glass of a certain size encounters another problem: most of the coloured glass available will appear very dark in large objects. For a glass artist to fully explore transparent colour and create a personal palette is difficult, because contrary to the field of ceramics, there are no established methods for colour testing and making.”
