Black, green, red, and silver oil spots burst onto the surface of this tea bowl. Imagine enchanting green tea heating the bowl from within. The elements of random and haphazard collide uniformly into beautiful designs. Most of the pieces we see contain a dark charcoal backdrop. This is the signature marking of quick artisans. Furutani rapidly cools the bowl, which allows for the formation of surface crystals. While this aesthetic may look easy because of the random appearance, it is pretty challenging to produce.
