If this formula is not unified correctly please contact us.
COLE - Co-efficient of Linear Expansion 3.7 x 10-6
MLRG - Frit Melting Range (C) 1350C

Suggested recipe cone 03 gas firing:
Frit 93%
Ball Clay 7
Black Glaze Stain 5
CMC 0.2

It appears the melting temperature of 1350C is overstated, it obviously melts earlier.
