Novel process for manufacturing dark-red enameled teapot

Abstract

The invention belongs to the field of manufacturing of porcelain, and relates to a novel process for manufacturing a dark-red enameled teapot. The process comprises the following steps of: manufacturing a teapot blank, manufacturing an accessory blank, installing the teapot blank and sintering the teapot, wherein before the teapot blank is sintered, the teapot is put into a drying room to be dried at the indoor temperature of 50 DEG C for 3 to 4 hours; in the step of sintering the teapot, the teapot blank is conveyed to a kiln to be heated to the temperature of between 100 and 120 DEG C; after the constant temperature is kept for 1 to 1.5 hours, the teapot blank is heated gradually, and the highest temperature is controlled to be between 1,170 and 1,200 DEG C; and the temperature is reduced gradually and is kept for 1 hour when reduced to 100 DEG C, and the teapot is taken out when the temperature is reduced to be between 55 and 45 DEG C. By improving the conventional process for manufacturing the dark-red enameled teapot, the dark-red enameled teapot is more practical and attractive, and the phenomenon of low yield of the dark-red enameled teapot due to poor mastering of mud properties or moisture and temperature is avoided simultaneously.

Description

technical field [0001] The invention belongs to the field of porcelain production, and relates to a novel production process of a purple sand teapot. Background technique [0002] After the mid-Ming Dynasty, teapots became more and more popular in China, and Yixing Zisha teapots have become the preferred choice for tea drinking because of their practical advantages of "neither taking away the fragrance nor the smell of cooked soup" (Wen Zhenheng's "Changwuzhi"). main utensils.

Since the Ming Dynasty, purple clay teapots have been the object of pursuit. [0003] "Work" is the soul of the value of Zisha teapot. There are tens of hundreds of processes to make a pot. Only through the careful production of var...
