Caithness Paperweight Gift Box Hand made in Scotland The Caithness Glass Party Poppers Green paperweight is full of fun with streams of green colours bursting as though exploding. The paperweight is created using glass powder colours which are indented in the glass form and then blown up, a bit like a normal balloon, but using compressed air. Since 1963 and now under the stewardship of Dartington crystal, the team of skilled Caithness glass designers and craftsmen continue to explore and push the boundaries of glass making whilst embracing modern developments in technology to produce high quality paperweights that are recognised the world over as the market leader.
