This product has a double structure by laminating the inner cup and the outer cup. Normally, double-layered pottery is fired by making a hole in the bottom of the body to prevent it from bursting due to the expansion of air during firing, and then closing the hole. However, with this method, the traces of the closed holes remain and it is not beautiful.
However, in 2013, we made it possible to fire in a completely sealed state by developing technology through many trials and errors in this kiln. As a result, I was able to make a beautiful cup with no trace of closing the hole.
