Paint each bisque tile with three medium coats of a majolica white glaze. Glaze the top and edges of each tile, leaving the back unglazed. Allow the glaze to dry between each coat. The three coats are necessary to ensure complete glaze coverage. When the third coat is dry, smooth out any brush marks using your fingertip.
Draw or transfer your majolica tile design to the white glazed tiles using clay carbon transfer paper. Drawing through the paper leaves a visible line on the unfired white glaze.
Paint your designs on the tiles using colored decorating glazes. Glaze manufacturers offer these glazes in a wide range of colors. A single coat of colored glaze on top of the majolica glaze produces a translucent shade. Two or three coats result in more solid coloration. Where two colors meet, the colors blend together during the firing process.
Fire the tiles in a ceramic kiln at medium speed to "Cone 05" -- 1870 degrees Fahrenheit. The firing process takes about eight hours, with another 24 hours for the kiln to cool down.
