The butterfly is an older tile made a few years ago ;it is fired several times and the colors and reliefpaste is applied in layers and seperate firings.Rob
I poured some casting clay in a mold, and in the wet clay I lay the leatherhard image of a boat(and a smoke trail).On the wet clay surrounding the boat I put some ceramic glaze glue.Then I added with the slipapplicator liquid clay to the surface;And very strange textures appeared which looks a bit like crystals.
