Outline of Final Research Achievements	It became clear by the drop test and freezing-thawing test using test pieces, that the unglazed bisque burning at specific temperature and coating lacquer was stronger than normal ceramics, and it can be return to earth easily unlike ceramics. I appealed for practical use of unglazing lacquerware for global environment maintenance by holding the trial product exhibition using this method.
