Dear Ben Shelton,
I would suggest that a "Preferred angle of 45 degrees" might be =
considered "Good" but shallower slopes will exhibit less movement of the =
wave front. Whatever angle you choose to use, standardise on that value =
if you intend comparing all of your glazes. But may also pay to design a =

You should find information in early industrial ceramic literature. =
