soda ash feldspar
Using Wood Ash in Glazes
Use a finer sieve to reduce the ash to a powder. 4 Rinse the sieved ash, pour off the water, then repeat 3–4 times. Let the ash settle from the water for a few days. 5. Drying the Ash. After washing is complete, siphon off the water and dry out the remaining sludge in bisque-fired bowls or plaster drying bowls.

Thermal Analysis of Reactions in Soda–Lime Silicate Glass
Two-component mixtures were prepared by choosing pairs in the same ratio as in a commercial container glass batch composition (sand-soda ash-calcite-dolomite-feldspar). The presence of silica in the silica-calcite system decreased the termination temperature of the decomposition of calcite, but did not alter the onset of decomposition.
