Caithness Glass is based in Scotland, production began in the 1960s but very few paperweights were produced until the 1970s. I first encountered Caithness paperweights during shopping sprees with my Mother during the early 1970s and have been fascinated by them ever since. Most of the weights available at that time had a modern Space theme and these abstract shapes and bubbles were unlike anything I had ever seen before. Clearly many others agree and the popularity of Caithnees glass paperweights has grown so that they are one of the largest paperweight producers in the world.
