This is the product of a series of tests to lower the thermal expansion of G2926B. Separate trials of substituting ZnO, SrO, Li2O for KNaO were tried (in each of these the brilliant surface was being marred by an orange peel like surface. This version is a hybrid approach, adding some Li2O to the SrO version (G2926I). It showed promise but needed better melt flow. After talking with tech support at Fusion Frits I decided to use their Frit 524 to source the SrO and get the Li2O from Spodumene.
The calculated expansion is dramatically lower, 5.6 vs. 6.4. This should thus be much more resistant to crazing. Of course, there are going to be some new issues. Spodumene introduces bubbles into the slurry in the bucket (washing it before use could solve this). Color response might also be different.
