Forming

We create a form out of potter's clay.
Forming method differs depending on the size and shape, could be by a gypsum mold when it is big.
Arita Porcelain Lab is one of the rare kiln equiped to fire big ware. After forming, pieces are let dry.

Bisque-firing

In order to prevent breakage and facilitate underglazing,
dried ware is fired at a relatively​ ​
low temperature of approximately 900˚C.

Underglazing (outline)

Patterns are first outlined.
"Gosu" colour that turns blue after firing is used for outlines.
Bisque-ware is very absorbent, this process to draw outlines with a brush requires skilled technique.

Underglazing (filling the patterns)

Paint is applied inside the outlined patterns.
Dami Fude is a thick brush but the tip is extremely thin, unique to Arita porcelain production for underglaze painting.
This technique of expressing the shades of colors with Dami Fude is one of the skills that requires long training.

Glazing

The bisque-ware is then dipped in our original glaze to coat the surface with a clear vitreous liquid. The ware becomes glossy, waterproof and stain-resistant.
The underglaze disappears when coated with glaze, but the patterns can be seen again after firing.

Glaze-firing (Honyaki)

The ware is then fired at a high temperature of approximately 1300˚C

Overglazing

Colors other than blue, such as red, green, yellow or gold are
painted to decorate the porcelain.

Firing after Overglazing

The ware are fired at a temperature of 720-800˚C lower than Honyaki to make the color durable, and it's finished.
