Abstract

The invention discloses a preparation method of white jade glass tableware, which comprises the following steps: preparing 64-66 parts of quartz sand, 7-9 parts of glass cullet, 15-21 parts of borax pentahydrate, 10-14 parts of sodium carbonate, 8-12 parts of ammonium dihydrogen phosphate, 6-9 parts of calcium carbonate, 2-4 parts of potassium carbonate, 1-3 parts of zinc oxide, 1-3 parts of aluminum oxide powder, 1.5-2.5 parts of barium carbonate and 0.06 part of cerium oxide; and evenly mixing the raw materials, melting in a melting furnace, forming, polishing, annealing and tempering. The whole production process can not generate fluorides, and thus, can not pollute the environment; and the prepared white jade glass tableware does not have toxicity, smell or qualitative change, and satisfies the national sanitary standard.

Description

technical field [0001] The invention relates to the field of glass tableware preparation, in particular to a method for preparing white jade crystal porcelain glass tableware. Background technique [0002] Traditional tableware is mainly made of ceramics, which have been used in daily life for thousands of years, but the waste products and fragments generated during the production process of ceramic tableware cannot be reused, and the durability of ceramic tableware The rapid change performance of cold and heat is poor, and the microwave transmittance is low, so it is not suitable for microwave heating. In addition, the brightly colored decorative glaze on ceramic tableware will precipitate heavy metals in contact with food for a long time, which will cause harm to the human body. When ceramics encounter acidic substances, their own Some toxic substances such as heavy metals will also be precipitated. [0003] In recent decades, tableware made of transparent tempered glass ...
