Three firings
Here’s how the Clay Tools tile for the Artist’s Tool Belt mural looked aftert each firing. The first is just the screened outlines, the second is with the shades of grey filled in, and the third is with the colors added. I spent just inordinate amounts of time drawing and redrawing and redesigning this piece, but when it came time to actually put some china paint on the tiles, it went pretty fast. Of course the screening step took very little time, maybe half and hour for all 10 or 12 of each image, including setup and cleanup. And filling in all the greys and colors took about 15 minutes for each firing of each tile.
