The Ceramic Color Database; a database of ceramic glaze has been constructed by organizing the data of more than 300,000 glaze test pieces. The large amount of glaze test pieces was created in the course of more than 80 years of ceramics research. The test pieces are valuable source materials in a sense that research processes and results are preserved in a visible manner. To further promote their use, the systematic organization of the vast amount of the test pieces and construction of the database was started in 1995. The open database on the internet was also constructed using the data from the original database. These databases provide fundamental information of ceramic glaze to the manufacturers and researchers of ceramics. The work of preparing the glaze test piece and improving its recipe is repeated many times on the development of new glaze. The information provided by the glaze database shortens the time required for the testing. The database has been frequently used by many kinds of users, especially after the database was opened on the internet. It was recognized that the database was useful in new R&D on ceramics. The database has been also used in the field of high school education. The database includes the data items such as glaze name, firing temperature, firing atmosphere, color, chemical composition, recipe, physical state, and other related information, as well as images of the glaze pieces. During the construction of the database, we faced many problems, and have received many requests from users. The database has been revised and improved corresponding to such issues. The use of the database, however, largely expanded as the open database was publicized on the Internet. The database has also been used in fields other than ceramics and in unexpected way. The recent communication speed and memory capacity of the Internet and usual computer are very different from those of 20 years ago when the open database was designed. The large reconstruction of the database is planed and now in progress. The database will provide larger amount of data. It will also possess new search function based on the recent developments in computer technology.
