Enter the formula and formula weight directly into the Insight MDT dialog (since it records materials as formulas).
Enter the analysis into an Insight recipe and enter the LOI using Override Calculated LOI (in the Calc menu). It will calculate the formula.

This borosilicate frit is high in calcium which means it will affect browns and iron oxide colors. This frit has a chemistry similar to an alumina addition to Frit 3134.

It is intended for use in partially fritted glazes for wall tile and pottery, in lead bisilicate dinnerware glazes in the cone 3-5 range.

Pictures
Frit balls fired at 1700F. Frit 3124 and 3195 are base glazes, Frit 3110 and 3249 modify expansion and 3134 is similar to 3124 but without any Al2O3. Gerstley Borate is a raw source of boron, it has a very high LOI.

This chart compares the gassing behavior of 6 materials (5 of which are very common in ceramic glazes) as they are fired from 500-1700F. It is a reminder that some late gassers overlap early melters.
