The pigments can be fired at very high temperatures of 1100ºc - 1300ºc to ensure they sink into the glaze, improving durability and resistance. Ideal for the more demanding hotelware market.
These are whiteware mugs (Plainsman M370) with tissue transfer designs that were applied at the leather hard stage. The pieces were then dried, bisque firing, clear glazed and then fired to cone 6. Tissue transfers are sold online in a wide range of designs (in full color also). They can also be made at home by silk screening the appropriate type of ink onto the tissue paper (you can make your own ink using ceramic pigments). These overglaze transparent recipes are G2934 matte (left) and G2926B glossy (right). The matte glaze softens the edges of the design. The pig is a good demonstration of how crisp the edges of lines can be (once the application techniques are mastered). This method of decorating is far less expensive than decals. And does not require an extra firing. While the ink is somewhat powdery, it can be stabilized with spray starch if pieces need to be transported for firing.
Not to be ignored are the two transparent glazes. Control of thickness is important. Too thick and they will go cloudy. Too think and they won't fire smooth. For use as a dipping glaze the slurry should be thixotropic. Using them as a brushing glaze, while taking longer to apply, does enable tighter control of thickness.

Ceramic Decals
This process of printing a design (using ceramic inks) onto film-coated paper to create a waterslide transfer. On wetting, the film decal can slide off the backing on to the glazed ware. |
