A lot of test pieces are usually produced in glaze studies. Data base is useful for an efficient utilization of them. Construction of two data base systems was attempted for several hundred thousand glaze test pieces accumulated during many years of ceramic studies at the National Industrial Research Institute of Nagoya. One system was for filing of glaze test pieces data as a library catalogue, while the other was opened to the public on Internet WWW. The data items of the systems were reference number, glaze name, firing temperature, firing type, color, surface conditions, Seger formula, coloring element, picture of test pieces, and so on. Construction of data items, evaluation method of color, classification of glaze, and treatment of pictures were discussed in both the systems.
