I know of three articles about these "frit flower in pot" weights:
- Paperweight Collectors Circle Newsletter 88, August 2005
Part of an article by Terry Johnson on three Ysart items. Two of these "frit flower" weights were discussed and illustrated.
- Paperweight Collectors Circle Newsletter 112, August 2013
Article by John Simmonds, illustrating one example of these type of weights. The article was a "shortened version" of the author's full article for the 2013 PCA Bulletin (referred to by Nick above)
- Annual Bulletin of the Paperweight Collectors Association Inc., 2013
Article by John Simmonds. This article illustrated ten of these weights, all of very similar shape and design.
During discussions among collectors following Terry Johnson's acquisition of two examples, I added information that I recalled a photograph of Salvador Ysart shown at a meeting of the Northern Paperweight Society. The photo included a "frit flower" weight of the same type and style.
In addition to the evidence of the shape, design, main glass colour (tint) and UV results, the colours of the frit in the known examples tie up very well to those used in Monart wares.
