The G1916Q recipe uses common Ferro frits and fits most low fire bodies (except this with high talc). It is easier to tune its recipe to adjust thermal expansion adjustable than others we have published in the past. And it melts well down to cone 06. And we have a strategy to reduce clouding and micro-bubbling. These five test tiles were fired using the 04DSDH schedule (drop-and-hold) firing schedule. Results are flawless. All exited from the kiln without crazing. The L215, L213, L210 and L212 samples subsequently survived a 300F/Icewater test without crazing, but the Buffstone did not (it needs a higher thermal expansion glaze adjustment). The L213 would not likely survive a cold-to-hot test without shivering (it needs a lower thermal expansion adjustment).
G1916Q - Low Fire Highly-Expansion-Adjustable Transparent
An expansion-adjustable cone 04-02 transparent glaze made using three common Ferro frits (low and high expansion), it produces an easy-to-use slurry.
Clouding in Transparent Glazes
There a many factors to deal with in your ceramic process to achieve transparent glazes that actually fire to a crystal-clear glass
