Process of making a shape from clay. There are roughly two types: potter's wheel molding and casting molding.

The molded and dried substrate is baked at a low temperature of approximately 900°C. This prevents the shrinkage rate from becoming large and cracking during the main firing, and makes it easier to paint. 

Paint the surface with paint material that turns indigo when baked.

Apply "glaze". Since "glaze" is a whitish liquid, the sketch disappears once, but when it is baked, it becomes transparent glass, so the surface becomes glossy and the pattern emerges. In addition, it does not allow water to pass through and is less likely to get dirty.

It is baked at a high temperature of about 1300°C using fuel such as firewood and gas.

This is the work of applying paints other than indigo, such as red, green, yellow, and gold, to the finished product.

In order to fix the paint applied with overpainting, it is baked at a low temperature of 700°C to 800°C.

The finished work shrinks about 15% compared to the base material immediately after molding.
