Best Kiln Wash to Protect Shelves from Glaze Drips
As an Amazon Associate I earn from qualifying purchases.
One runny glaze can bond a pot to a bare shelf permanently, and chiseling it off usually takes a chunk of shelf with it. Kiln wash is the cheap insurance layer that stops this: a refractory coating that lets fired glaze drips pop off with a light scrape. Not all washes behave the same, though. Some flake into glaze surfaces below, some crawl off the shelf during application, and some fail at cone 10. Here we compare pre-mixed washes against powder formulas you mix yourself, look at alumina-based recipes for high fire, and walk through application technique, from surface prep and coat count to when a shelf needs stripping and recoating.
