DENS - Density (Specific Gravity) 6.6-6.8
COLE - Co-efficient of Linear Expansion 9.3 x 10-6 (50-450C)
MLRG - Frit Melting Range (C) 700-784C

This is a standard frit formula of 1 molar part of PbO and .66 of SiO2. The powder is light yellow. Some people consider a lead monosilicate to be 1PbO - 1SiO2. Frits of both chemistries are available and they both claim to be lead monosilicate.
