Karatsu pottery
The uniqueness of Karatsu ware—or Karatsu Yaki—lies in its glaze and clay. The glaze most commonly used in Karatsu ware is the soil ash glaze. It comes from wood ash and is the most widespread basic glaze of Karatsu ware. The second most commonly used glaze—the straw ash glaze—uses the cloudy characteristic of straw ash to bake the Karatsu ware and give it a cloudy tint. Other glazes such as iron glaze, ash glaze etc., are also used.
While there are many types of clay used to make Karatsu ware, the most commonly used is one known as Suname in Japanese—”Suna” means sand and “me” means appearance—due to the characteristic roughness of this clay. The second most commonly-used clay is called fine Suname; it is strongly adhesive. Fine Suname clay has parts that are highly rich in iron and other parts that are not. The former turns blackish brown after the firing process. As the latter becomes near-white upon firing, motifs brushed onto this part of the clay develop a vivid color.

Words where two kinds of glazes are applied over the ware—cloudy straw glaze and amber glaze (a kind of iron glaze)—whilst allowing the second layer to run over the first are known as Chosen Karatsu. The cloudy straw glaze and amber glaze weave into each other and giving rise to a exquisite flowing pattern, making works with the Chosen Karatsu style aesthetic as a decorative pieces.
