Dichroic glass - created originally for aerospace industries, refers to the metallic coloured surfaces of my glass pendants and earrings. The colours are sourced from metallic oxides such as titanium, zirconium, aluminium, and silicon dioixde or quartz which are heat vapourised in a kiln chamber and vaccum fired onto the surface of the glass. It is from this metallic surface that Robyn etches her unique designs. The viewer will see both reflected and transmitted colours depending on the viewing angle. Dichroic glass can be encased with clear glass or left uncoated for textural effects, both produce remarkable effects and both are durable surfaces.
