Can there be too much boron in a glaze?

For Flux Sake

About

This week's show starts with a discussion of a recent viral ceramic video and the merits of a potter dipping pots in water immediately after glazing. The gang also answer listener questions about the amount of boron glazes, melting in cone 6 mattes, and a safety concern from drinking out of a crazed mug.
