This is important because I am searching for a balance between the degree of insight-live.com/glossary/112">melt fluidity of my original crazing glaze but having a thermal expansion to fit my porcelain (this is G3806E and F). With each adjustment to the chemistry to drop the thermal expansion I do a firing to compare the melt fluidity with the previous iteration. On the right I have too much boron, it’s melting more than I want. And bubbling.
