Earth walls are divided into three categories according to the production methods, that is, kneading with much glue, kneading with little glue and kneading with water. The method of kneading with much glue is widely used for the walls of guest rooms in Kanazawa. The wall of Cobalt Blue Room in Sei-son-kaku Villa is a famous example. The wall is made of earth color, sand and natural glue and it is used as a sample of the kind in sample books. You can see the tradition of multi-layered earth walls kneaded with glue. This example well expresses our playful spirit. Why don't you join our world of plaster art?
