Helen Stone asks if how the frits GF111 compares to 3134:
According to Tony Hansens "Insight" software the are for practical purposes
identical.
GF111/3134
CaO .683/.683
Na2O .317/.317
B2O3 .640/.633
SiO2 1.475/1.475
There also is percentage by weight data given for GF146 in John Conrads
"Advanced Ceramic Manual" on pg 239:
K2O 1.00
Na2O 16.40
CaO .30
ZnO 4.20
AL2O3 23.90
B2O3 54.20
With a note "Grind wheel abrasive bond frit".
Hope this helps

Looks like Fusion frit F12 is a ringer too but with a little alumina
