Enviromenetal measures and their technologies on the production process of tableware (bone china) are shown.
1) Muddy sludge, which is recovered from low materials treatment process and shape making process, is recycled as low materials.
2) Water from glazing process contain lead compounds and suspended solid. This water is treated on the special lead deposit process.
3) Tableware is glazed by lead free glazing fritt, which is invented for bone china. The contents of components in this fritt are 61-66 mol%, Al2O3 8-10 mol%, MgO 0.1-2 mol%, Li2O 2-5 mol%, K201-4 mol%, Na20 2-6 mol%, B203 10-15 mol% and R20/R0=2-3.5 mol%.
