For Image Transfers, use a laser printer that has iron oxide in the toner (we have a Canon MF3200 series laser printer). We print on waterslide decal paper purchased from BelDecal.com; apply the decals to a finished cone 6 piece, then refire to 04. Test glaze combinations and firing times. More info can be found in the Paul Wandless Image Transfer on Clay (Lark ceramics book) Most glazes we use are mixed from recipes in our studio. For cone 6 glazes we sometimes use Mid-South Ceramics Opulance glazes, http://www.opulenceglaze.com/. We use Highwater Clay’s Raku clay, http://www.highwaterclays.com/.
