I've used several brands of dry glazes. Coyote so far has been my favorite. On the down side, they are expensive. If you are interested in mixing your own I would highly recommend buying a copy of "Mastering Cone 6 Glazes." It has several good base glazes that can be easily altered. Also, Pottery Making Illustrated recently ran a piece on setting up a glaze studio. I found it very informative. If your sharing a studio with others the initial investment might be a reasonable choice. A good source for buckets is your local pizza dive. I talked to the manager and they saved buckets for me, FREE!
My first pottery instuctor told us in our first class, "if you don't like working in a kitchen, you won't like working in a studio." I think she hit the nail on the head. It's exact measuring, cleaning up and using your noodle to find new uses for items you have or can make use of.
