Abstract

The invention discloses a corrosion-resistant glaze material for a pottery pot. The corrosion-resistant glaze is prepared from the following raw materials in parts by weight: 20 to 50 parts of kaolin, 5 to 20 parts of limestone, 7 to 21 parts of potassium feldspar, 8 to 24 parts of lepidolite, 1 to 5 parts of zirconium oxide, 2.6 to 3.4 parts of zinc oxide, 1.3 to 2.7 parts of tin oxide, 10 to 20 parts of terpene resin and 15 to 30 parts of 1-hydroxyethylidene-1, 1-diphosphonate. The invention further discloses a glazing method of the corrosion-resistant glaze for the pottery pot, the process is simple, and raw materials are easy to obtain. The pottery pot glaze prepared by the method has the characteristic of excellent corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of production and processing of pottery pots, in particular to a corrosion-resistant glaze for pottery pots and a glaze application method thereof. Background technique [0002] Ceramics is a general term for pottery and porcelain, and pottery and porcelain have different textures and properties. Pottery is made of clay with high viscosity and strong plasticity as the main raw material. It is opaque, has fine pores and weak water absorption, and the sound of hitting is muddy. Porcelain is made of clay, feldspar and quartz, translucent, non-absorbent, anti-corrosion, hard and compact, and crisp when knocked. [0003] Glaze is a kind of silicate. The glaze applied on ceramics is generally made of quartz, feldspar, and clay. After grinding and adding water, it is coated on the surface of the green body and melted by roasting at a certain temperature. The temperature drops When, a glassy thin layer on the cera...
