Shaner's Clear Glynnis Lessing

Instructions

Originally, this recipe came from Lillstreet Studios in Chicago, Illinois. This is a nice, easy to work with glaze that can be thinned, doesn’t show minor flaws like drips, and travels well unfired as it has a hard (not powdery, flaky) dried surface.

Fits cone-10 porcelain, B-clay, and stoneware. It can be fired in either oxidation or reduction but with reduction, it takes on a slight blue cast, which I really like. This glaze tends to absorb iron, so it can eradicate an image or pattern if you put it over a red iron–based slip or oxide.

This glaze mixes very nicely if slaked overnight. I apply the glaze by dipping my pots. I rinse each piece in water—not soaking it—and immediately dip it in the glaze. This gives me a very thin, even coat. I use a green scrubby lightly to remove drips after the glaze has dried. If I have a huge piece, I use a mouth-blowing sprayer. This glaze works very well using that method too. I also can apply it by brush to fix flaws. Please note, if you apply this too thickly, microbubbles will make it appear milky.
