This past week I got back to work on this project by creating 4 test glazes and firing them. The four glazes and the receipes follow. Each pot was dipped so that a part of the pot has one coat of glaze, another 2 coats and another 3 coats.
#1 & #2 - Vera's Emerald Gloss Green for dark clay bodies - Modified by Ron Roy
I tested this recipe last January by adjusting the copper carbonate and couldn't get the green I was looking far and actually all I got was blue so I thought I would try ajusting the rutile to see what would happen.

How will you put the logo on the pot? A stamp? A decal? I have been asked to do a similar (much smaller scale) project for my local radio station, and have been playing with ideas.

I am using a stamp that I had made at a local business that one of our guild members owns.
