Jianzhan reducing rod and its preparation method and Jianzhan firing method

Abstract

The invention discloses a Jianzhan porcelain reduction bar as well as a preparation method and a Jianzhan porcelain firing method thereof. The Jianzhan porcelain reduction bar is prepared from the following components in parts by weight: 38-42 parts of rosin, 7-13 parts of abietic acid, 8-12 parts of oil of turpentine, 17-23 parts of pine wood flour, 4-6 parts of wild loquat root powder, 4-6 partsof red-stone sticky powder, 5-7 parts of elm bark powder, 4-7 parts of corn starch, 8-13 parts of charcoal dust and 18-22 parts of water. The Jianzhan porcelain reduction bar disclosed by the invention is stable in component and excellent in combustibility. A certain amount of Jianzhan porcelain reduction bar is added in a Jianzhan porcelain firing process according to needs, combustion conditions and a reducing atmosphere in a kiln can be accurately controlled, the quality stability of the finished Jianzhan porcelain is greatly improved, and hare's fur or oil drop Jianzhan porcelain with beautiful stripes can be conveniently fired.

Description

technical field [0001] The invention relates to a firing process of porcelain, in particular to a firing method of Jianzhan. Background technique [0002] China is the hometown of porcelain, and porcelain is an important creation of the Chinese working people. Jianzhan is a typical representative of black-glazed porcelain. Black-glazed porcelain has been fired very early in my country. It can be traced back to the Eastern Han Dynasty, and Jianzhan reached its peak in the Song Dynasty. Jianzhan is produced in Shuiji Town, Jianyang District, Nanping City, Fujian Province. Jianzhan occupies a place in Chinese porcelain because of its simple shape, unpredictable and colorful glaze color, which fully displays the magic and depth of black porcelain. [0003] There are many processes in the manufacture of Jianzhan, mainly including body and glaze preparation, casting, trimming, biscuit firing, glazing and roasting. Among them, the most important step is roasting. The quality of t...

Problems solved by technology

Since pine wood is mined naturally, its components are unstable, and the content of pine wood, turpentine and other components is uncertain. The same weight of pine wood cannot guarantee that its components are consistent, or even have a large difference.

In this way, when the pine wood is put into the kiln, under the same furnace temperature, the combustion conditions are different, which is likely to cause fluctuations in the reducing atmosphere and affect the stability of the quality of the finished product.
