Bomma was intended to be very close to SP87 as a glass and SP87 is well known for devitrifying as a casting glass. SP has barium in it which doesn't bode well for being a weaker glass structurally. It does brighten soda glasses.
I'd like to hear more about it going south.
Where are we going and why am I in this basket?
