Glaze materials are expensive and many times we test glazes that has potential, but is not necessary what we wanted, or it may take many more tests to get what we want. I am one of those potters that do not easily trash anything. So I am always making plans to utilize what I tested and many times I found hidden treasures where I least expected it. In this video I show you how I use glaze tests from the Glazing made easy e-course that either have some potential or did not work at all.
You can also create new and fresh glazes from old glazes. Just make sure that you test it properly and that the end result fit your clay body. Remember to take notes. And remember, there comes a time when tests of tests should be trashed.
