Brush-on commercial pottery glazes are perfect? Not quite!

Brushing glazes are great sometimes. But they would be even greater if the recipe was available. Then it would be possible to make it if they decide to discontinue the product. Or if your retailer does not have it. Or to make a dipping glaze version for all the times when that is the better way to apply. The glaze manufacturer did not consider glaze fit with your clay body, if they work well together it is by accident. But if you have transparent and matte base recipes that that work on your clay body then adding stains, variegators and opacifiers is easy. And making a brushing glaze version of any of them. Don't have base recipes??? Let's get started developing them with an account at insight-live.com (and the know-how you will find there)!

Common dipping glazes converted to jars of high SG brushing

These are cone 6 Alberta Slip recipes that have been brushed onto the outsides of mugs (three coats gave very thick coverage). Recipes are GA6-C Rutile Blue on the outside of the left mug, GA6-F Alberta Slip Oatmeal on the outside of the center mug and GA6-F Oatmeal over G2926B black on the outside of the right mug). These one-pint jars were made using 500g of powder, 280g of water and 75g of Laguna CMC gum solution (equivalent of adding 1% powdered CMC). Because no Veegum is being used this blender mixes to a slurry of high 1.6 specific gravity (for thicker coverage per coat than commercial glazes having much more water). This approach is good for recipes high in Alberta Slip. The gum removes the need for roasting part of it, reduces the water needed and the plasticity of the Alberta Slip helps suspend the slurry.
