I recently tested decals on my current lineup of glazes. The decals came from decalpaper.com. The test tiles were made from Amaco’s Warm Brown Stoneware, bisque fired and then each dipped in one of my current glazes. After glaze firing each tile to ^6 I applied one of the water slide decals and put the tiles through another bisque fire. The images show the tiles just after I applied the decals and then after the decals were fired on.
I learned a little bit about ceramic decals in the surface class I took this past summer at the Goshen Clay Artist’s Guild. During the class I spent most of my time working with the crystalline glazes and never got a chance to try the decals.
