Alisa and Claus Clausen on fri 22 sep 00
Receipe source is Clayart Archives, Paul Lewing.
Tested on light grey mid range stoneware fired to 1220c oxidation.
27 Custer spar
9 Frit 3134
8 Gertely Borate
Subs. were local frit and spar.
Clear, stable, shiny gloss. No noticeable differences where double =
dipped. Some crystals where especially thick under rim.
Same receipe tested with 8 colemanite for Gerstley Borate.
No discernable difference, expect colemantite version had a very small =
bluish pool in test bowl center.
I think this sub. works.
