The obvara firing process, which originated in Eastern Europe around the 12th Century, involves scalding the finish on the pottery to seal the porous surface. Similar to the raku pottery process, a bisqued pot is heated, in this case to 1650°F (899°C) and removed from the heat.
What is the Mishima technique?
Mishima is a technique of inlaying slip, underglaze, or even clay into a contrasting clay body, the main clay body of the pottery piece. This technique allows for extremely fine, intricate design work with hard, sharp edges that can be difficult to reliably replicate in any other way.
Can you underglaze leather hard clay?
The beauty of underglaze is it can be used on either greenware or bisque-fired clay. The image below shows underglaze applied to leather-hard pieces that are ready to be bisque-fired. One of the advantages of using underglazes is you can mix the colors to create a painterly effect.

What is the difference between underglaze and overglaze?
What is the important difference between overglaze and underglaze is when the paint is apllied. In the case of overglaze, you burn the glazing on the porcelain and then paint it. While when using underglaze the paint is applied on the unglazed porcelain and then the glaze is applied over the paint. Thus underglaze.
What’s the difference between sgraffito and Mishima?
What is Mishima? Mishima on the other hand, is essentially the opposite of sgraffito, as you inlay the slip or underglaze, or fill in the color, rather than scratch the top layer away to reveal it. You can add additional colors to the piece to finish the design before firing.
