IT's taken me awhile. I started there three years ago and that was the first thing i tried to do and boy howdy did i find i needed to learn alot but then again i am using high fire clay and gas kiln because that is what is available not necessarily what is easiest to use. STilll learning, with miles and miles to go. When you do if there is any questions i could help with i would be more then happy to share what i have learned along the way.
