I have used this kiln wash for the last 10 years. IT IS AWESOME. It doesn't flake off the shelves and glaze drips clean easily off of it. It is the only kiln wash I would use in a school or home studio setting. I hate the flaky kiln wash from Amaco or the home made kiln wash recipes - neither of those is as good as Lee's Kiln Wash from Axner Pottery .com
