Glaze Suspension & Binder Products I use.
Crystalline glaze recipes have little to no clay content, so there are problems in terms of settling when stored even for short periods. Cracks that form in the raw dried state can result in non-adhesion and crawling when these glazes are fired. Using binders and suspension agents as additions to the glaze base will help with most of these issues.
I premix my binder/suspender in water so that it is in solution and available when I need it. Refer to the post on: Adding Water, Suspenders, & Binders to a Glaze for more on this process.
I usually prefer combinations of CMC, V-Gum T, and MAGMA as my binder/suspender.
V-gum CER is also a good product, but when using CMC and V-gum T together, I prefer a different ratio.
David Pier designed MAGMA, and I was lucky to get a sample before it officially hit the shelves… it took very little to have an effect, and I liked it right away.
Another friend, John Tilton has recommended calcium nitrate. He uses it to aid in brushing and thinks that within certain conditions, it might aid in spraying as well. Personally, I like a thinner rather than a thicker consistency when spraying, so it would require further testing.
