|Trio was an unusual set, as it was created without using any colour. The only materials used were clear glass, silica sand, and charcoal. The design theme is based upon the number Three!
Spectre was the only weight that Caithness ever made where the large silvery bubble was actually injected into the glass using a Hypodermic needle! I wanted the emerald green design form to remain absolutely flat, and this was the only way to obtain this effect.
