I have two glaze recipes from the same source. One calls for EP Kaolin. And the other just states Kaolin. Are they interchangeable or should i likely buy EPK and another general purpose Kaolin?

For a glaze recipe they are interchangeable will not make much difference. Hope this helps.

You say the chemical makeup of this kaolin is 36% Al2O3 and 48% SiO2. What makes up the other 16%?

Hi, trace elements such as Iron, Sodium, Calcium, Magnesium and a loss on ignition of around 11.5%
Hope this helps
