In the seven hot springs bathing pools, the bathrooms, restrooms and other space in Kazan Hotel, there were more than 10 types of ceramic tiles that were used. The colors of these tiles were chosen to be in calm tones such as grey green, brown, light brown, blue and various overglazed tiles; for example, thirteen-striped tiles, relief tiles and patterned tiles. Currently, in the bathing pool and other spots, our guests can still see and appreciate these decorative tiles which were really popular in the Showa period (1926-1989 A.D.). In the Japanese domination period, especially the Taisho (1912-1926 A.D.) and the Showa periods before the War, general people could not afford ceramic tiles to decorate their houses. Only the bathrooms, restrooms and entrance space of few large residences, or Western-styled reformed dwellings or other public buildings might use the material of ceramic tiles to decorate some parts of the structures. Guizikeng in Beitou was the only mining area for white ceramic clay in Taiwan (the mining is prohibited now). The fired ceramic products made of the ceramic clay from this area are generally called "Beitou-yaki."
