But it can be intimidating to delve into glaze chemistry. It is extremely complex, and includes the word ‘chemistry’ in its name, which to some (me included) is an immediate red flag. So in today’s post, Greg Daly gives five excellent tips for getting the most out of glaze testing. Read on, and then get out there and test!
