I inherited some lovely glass dessert plates from my mother that I would like more information on. I have searched the web and have found little information. The plates are a celadon green, 7" in diameter. The S & W fleur-de-lys logo is on the bottom with the work "England" underneath, acid-etched into the plate bottom. The plates are fairly transparent, appear to be hand-made in that each plate is slightly different in thickness and concavity. One plate has the numbers 2256 hand-scratched into the bottom.
Are these jade glass, vaseline glass, alabaster glass, uranium glass? Are they rare? I thought they must be since there is so little information about S & W plates.
I have posted two photos to the Glass Gallery.
Any information would be appreciated.
