Here is a quick video to show you how we handle the "finishing" of the clay faces. Years ago I went to a conference....and a professional clay artist gave us "permission" not to feel bad about not glazing in our elementary art rooms. He said there are other options that are more time & cost effective. The reality that when we do a clay project there will be over a hundred of that project makes glazing a bit daunting. This is just one way we finish our pieces in my art room. The kids love it & it looks great.
