Hi all
The paperweight is commonly known as stain glass the method although well known prior to, was actually patented back in 1857 by Benjamin Richardson and thereafter everyone seemed to jump on the bandwagon. Boulton and Mill sold it under the name “Nacre de Perle”, Stevens and Williams called it “Verre de Soie, and with Walsh Walsh it was called “Broche”. Richardson’s then went patriotically Scottish and Used “Tartan”. The name Satin glass seems to emanate from America where it is also known as “Plush” or “Pearl Satin”
Hope this helps a little ,regards Tim.
