It was not until the middle of the Meiji period (1868-1912) that lime glaze began to be used in Japan, replacing the wooden ash glaze native to the Orient. At first, some people made the mistake of using baked lime. Lime glaze is actually a limestone glaze, and the use of calcium calcium as a solvent is not much different from that of wood-ash glaze, but since lime is more pure, a smaller amount is needed than wood ash. The dosage of lime plaster should be four-tenths of that of chisel plaster. Lime glazes were used because they were inexpensive, but they were not suitable for making stained wares and were inconvenient for firing lime, so talc (lime stone) glazes were used in later years.
