preparation example Construction

[0029] A kind of preparation technology of gray spot tianmu oil drop glaze, comprises the following steps:

[0030] Step 1. After mixing the carcass raw materials evenly according to a certain ratio, stir them with water at a mass ratio of 1:1 to obtain a mixture; grind the mixture into a slurry with a ball mill, and finely grind it for 20-60 minutes to reach a fineness of 250-300 After mixing and beating the mud for 6-20 hours, the resulting whipped mud is molded into a plain tire, and the plain tire is put into a kiln for 4-5 hours at 860-950°C for 4-5 hours, and then cooled to room temperature with the furnace ,spare;

[0031] Step 2: Mix the Tianmu glaze raw materials according to a certain ratio and put them into the ball mill, add water with the same total weight as the Tianmu glaze raw materials, start the wet grinding for 40-80 minutes, and the fineness of the wet-milled Tianmu glaze slurry is 300-400 mesh, statically Place it for 24 hours, use a moisture meter to det...

Abstract

Provided is a preparation process of greyness temmoku oil-spot glaze porcelain. The preparation process comprises the following steps of 1, body firing, 2, glaze preparation, 3, glazing and 4, firing. The glaze is composed of black powder soil and ferrotitanium ore, the black powder soil accounts for 65-75 parts of the total weight of temmoku glaze raw materials, and the ferrotitanium ore accounts for 25-35 parts of the total weight of the temmoku glaze raw materials. The preparation process of the greyness temmoku oil-spot glaze porcelain comprises the steps that the ferrotitanium ore is included in the glaze materials, and comprises the main components of pseudobrookite, Ti is adopted as color development reagent of temmoku glaze greyness, bubbles in a glaze layer float upwards to break through a glaze face, grey corrosion is left on the glaze face, and due to the fact that iron elements are black in the firing process, the glazing color is shown as black-background grain with the grey corrosion. Due to the fact that a large amount of the black powder soil is added to the glaze materials, the glaze material formula of greyness temmoku oil-spot glaze fired in ancient times is restored to the maximum extent, and the fired glaze is plain and dignified in color, and is of great momentum.

Description

technical field [0001] The invention relates to the field of ceramic manufacturing, in particular to a preparation process for gray-spotted Tianmu oil-drop glazed porcelain. Background technique [0002] Tianmu glaze is the name of the black cup fired in Jian kiln in Japan. Jian kiln is represented by Jianyang, Fujian Province today. The kiln site is located in Shuiji Town, Jianyang, and is famous for producing black porcelain. It was created in the Tang Dynasty, became the most popular in the Song Dynasty, especially the Southern Song Dynasty, and ended in the Qing Dynasty. [0003] Among the varieties of ceramic art glazes in our country, "Tianmu glaze" originated from the Song Dynasty, and it first referred to the tea cups of Jian Kiln in Fujian and Jizhou Kiln in Jiangxi. Oil drop, iron embroidery, Yaobian, etc. The firing technique of Tianmu glaze is called "divine skill". The magical skill "divine" is applying a glaze color. Once fired, it will present colorful, unp...
