Colored glaze raindrop glaze ceramic firing technology

Abstract

The invention relates to a colored glaze raindrop glaze ceramic firing technology. The colored glaze raindrop glaze ceramic firing technology comprises the following steps that step one, blanking is carried out, and a molded blank piece as required is prepared through slip casting, throwing or mechanical molding; step two, biscuit firing is carried out, after inner glaze is applied to the blank piece, the blank not applied with outer glaze is sintered, so that the blank piece is sintered and the water absorption is less than 1%; step three, glazing is carried out, and once or more than once glazing is carried out on the blank piece; and step four, high-temperature firing is carried out, and high-temperature firing is carried out under 1250-1300 DEG C. The colored glaze raindrop glaze ceramic firing technology has the advantages that liquefied gas, natural gas and dynamic electricity are adopted as fuel, firing can be completed by about ten hours, and the problems that raw coal firing for ancient law production is long in time consumption and serious in coal resource waste and environment pollution are solved; and the biscuit firing is that sintering is carried out on the blank piece not applied with the outer glaze, so that the blank piece is sintered and the water absorption is less than 1%.

Description

technical field [0001] The invention belongs to the field of firing ceramics, in particular to a firing process of colored glaze raindrop glaze ceramics. Background technique [0002] The development history of ceramics is an important part of the history of Chinese civilization. As one of the four ancient civilizations, China has made outstanding contributions to the progress and development of human society. Among them, the invention and development of ceramics has unique significance. Different dynasties and dynasties in Chinese history have different artistic styles and different technical characteristics. [0003] In the firing process of ceramics, the finished ceramics obtained by different methods are also different. Ceramics are generally fired from pottery blanks. Traditional and contemporary ceramic firing processes, ancient methods of production are fired with raw coal, and the firing process requires About 80 hours, it takes a long time and is not environmentall...

AI Technical Summary

Problems solved by technology

[0003] In the firing process of ceramics, the finished ceramics obtained by different methods are also different. Ceramics are generally fired from pottery blanks. Traditional and contemporary ceramic firing processes, ancient methods of production are fired with raw coal, and the firing process requires About 80 hours, time-consuming, not environmentally friendly, resulting in waste of raw materials, therefore, it is necessary to study a color glaze raindrop glaze ceramic firing process with a short firing time
