Abstract

A glazing technology for purple-sand tea sets relates to the technical field of purple sand and comprises the following technological steps: 1) preparing a green body, specifically taking purple sand at Huainan area of Anhui province of China as a main material to prepare the green body; 2) taking out the green body, baking to dry at a room-temperature environment, so as to prevent deformation of the green body; 3) sintering the green body, specifically for first sintering in a kiln, employing reduction flame for sintering, heating to 950-1050 DEG C, and sintering for 16-18 h, so as to mainly eliminate humidity and remove alkali in the green body; 4) keeping warm for 10-20 min, naturally cooling and discharging from the kiln; 5) uniformly glazing the surface of the green body; and 6) sintering the glazed green body, specifically for secondary sintering in a kiln, employing reduction flame for sintering, sintering at 130 DEG C for 20 h, keeping warm for 10-20 min, and naturally cooling and discharging out of the kiln. The technology is simple, and by adding compositions such as shells, bluestone and the like, the sintered tea set has spots on the surface and has beautiful color.

Description

technical field [0001] The invention relates to the technical field of purple sand, in particular to a glaze and a glazing process for a purple sand tea set. Background technique [0002] Zisha products, also known as Zisha ware and Zisha pottery, are ceramic products made of special clay, which can be made into various ceramic products commonly used in daily life. Zisha tea set is a kind of pottery tea set. It is dense and hard, with natural mud color. Most of them are purple sand, and there are also red sand and white sand. The fire temperature of finished pottery is 1100-1200 ℃, without water absorption, and the sound is rough and rhyme is long. It is cold-resistant and heat-resistant, making tea without the taste of cooked soup, and can keep the fragrance, and the heat transfer is slow, so it is not easy to scald your hands, and it will not burst when you use it to stew tea. Therefore, there was a saying in history that "a pot weighs no more than two, and the price wei...
