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 â€śNacre de Perleâ€ť, Stevens and Williams called it â€śVerre de Soie, and with Walsh Walsh it was called â€śBrocheâ€ť. Richardsonâ€™s then went patriotically Scottish and Used â€śTartanâ€ť. The name Satin glass seems to emanate from America where it is also known as â€śPlushâ€ť or â€śPearl Satinâ€ť
Hope this helps a little ,regards Tim.
