WG stone may be Cornish stone.
A company I used to work for processed this and labelled it WG Stone as =
an abbreviation for Wet Ground Stone.
In apperance it was lump of approx. thumb size, damp at around 10% =
moisture and a very pale green/blue colour. (The lalter is from a =
vegetable identification stain and not as has been suggested from =
fluorine. Without the stain, which burns out, it would be white.)
If you email me a scan/photograph of the label I can confirm or =
otherwise.
Also, and whilst not definitive, fire a small amount to 1300oC. If it's =
a flux glass will be formed though if it's a refractory material, say =
kaolin or quartz, it'll still be friable.
Regards,
Andrew
