thanks guys i checked out all the web sights i could and decided on this interoperation of the form along with a few mods along the way. glad you like it.
the glaze is going to be a combo of iron, copper and a touch of zinc white. i have a blue but have not figured it in yet.
I want to add some talc to the zinc glaze and see if I get some crawl but that is an experiment for the future.
