There are some materials for coasters in Japan, such as metals (Tin, copper, iron) wood (lacquer) , porcelain…etc
Tin will have good color change as it is aged. Tin coasters goes with white porcelain cups very well. Elegant and noble. Tin coasters are often used for senchado tea ceremony.
Front side of cup & front side of coaster should face to guest.
