In the year 2016, Arita-ware was celebrated its 400th anniversary. This work was one of the projects of"Saga Prefectural Project to Commemorate the 400th Anniversary of the Founding of Arita Ceramics".
Two purposes of this project were to develop the high strengthened porcelain and high precision porcelain.
As the result, the flexural strength of the newly developed strengthened porcelain reached 350 MPa, andwe were success to develop the no-shrinkage no-firing deformation porous ceramics.

Improvement in slip casting process for porcelain
Nobuaki KAMOCHI, Kana YAMASAKI
Saga Ceramics Research Laboratory
Slip casting is one of the main forming methods to make complex shaped porcelains in Hizen area.
However, depending on the shapes, a sink mark is generated on a thick part and a crack is generated in athin part. In this research, the influence of slip conditions to precision of products was evaluated. As aresult, the sink mark was effectively prevented even 20mm over thickness products and the cracks were
not occurred even in the thin products by effect of addition of a flocculant. 㻌㻌⭯ᆺ䛾ᨵⰋ䛰䛡䛷䛿ᑐᛂᅔ㞴䛺ᙧ≧䛾ᅽຊ㗪㎸䜏ᡂᙧ㻝㻚㻌 䛿䛨䜑䛻㻌㗪㎸䜏ᡂᙧ䛿⫧๓ᆅ༊䛻䛚䛡䜛☢ჾ䛾㔞⏘䛻䛚䛔䛶䜔䚸ᚑ᮶䛾᤼Ἶ㗪㎸䜏䛷䛿ᆺෆ䛷๭䜜䛶䛧䜎䛖䜘䛖䛺」

Evaluation of the property and the practicality of porcelain clay from acid-treated Amakusa
porcelain stone
Yuzo SHIWA, Makoto TERASAKI
Saga Ceramics Research Laboratory
The white porcelain is a synonym for Arita ware. In recent years, securing of raw materials for white
porcelain has been a problem due to depletion of high-grade Amakusa porcelain stone and reduction ofmining staff. It is necessary to use more acid-treated porcelain stone which lowed iron content byhydrochloric acid treatment of low grade porcelain stone to continue production of white porcelain. In
this project, we evaluated the practicality of porcelain clay produced from acid-treated porcelain stone inorder to disseminate acid-treated stone to the ceramic industry in Arita area. This year, we preparedspecial-grade test clay for wheel throwing only with acid-treated porcelain stone, then it turned out that
there was no problem in using acid-treated clay with the cooperation of porcelain artists and others in
Arita.㻌
