21 Whiting

Subs. were local frit and spar.

Clear, stable, shiny gloss. No noticeable differences where double =

Nice.

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.
Best regards,
Alisa in Denmark
