What you need to know about Shigaraki ware - Large-scale production
After the war, demand for Shigaraki ware braziers increased, and production peaked around 1955, with braziers being shipped all over the country. At one time, it is said that about 90% of the braziers in the country were made here in Shigaraki.
There are many distinctive glazes, such as the ultramarine sea cucumber glaze and the flowing glaze called tortoiseshell glaze. Various decorative techniques are also used, such as those depicting landscape paintings and a technique called itchin, which involves piling up mud to create pictures.

What's even more surprising is that these braziers were fired in large quantities in climbing kilns fueled by firewood. These braziers are the result of the pinnacle of technology at the time, from molding to firing.
This tradition of braziers continues as a tradition of large-scale production in Shigaraki, leading to planters, flower pots, and now ceramic bathtubs.
