The secret to cool bodies and glazes is alot of testing. But how will you be able to learn from that testing without a good place to store the recipes? Document the successes and failures? Do it in your account at

Nepheline Syenite10.09.8%
Ball Clay60.058.8%


This is the product of a series of tests where the percentage of feldspar was progressively reduced (from 25% originally) to reduce the firing shrinkage (it is important that engobes shrink the same as the body they are on or they will flake or crack off during firing or later during ware use or exposure to the elements). Amazingly only 10% nepheline syenite is needed.

This engobe is very plastic so it sticks well to leather hard clay.

The zircopax makes this fire quite white. If you want black, switch it to 10% Mason 6600. Be careful with other stains, some of them will flux and increase the fired shrinkage.

To mix this follow the instructions on using an engobe at the Digitalfire Reference Library.
