AI Technical Summary

Benefits of technology

This new method described in this patented describes different ways to create special types of glass called “cerams” or“porels”. By mixing these ingredients together, they help control how many holes occur when burning them into an oven before curving down. They have improved properties like resistance against heat shocks and durability over long periods of use compared to existing methods. Additionally, their presence improves visual appeal because there're fewer colors visible through the colored crystal structure formed within the glass itself. Overall, this technology allows for better quality ceramia production while maintaining desired characteristics.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving the quality of jewelry made through traditional methods like burning or melting gold powder onto stone surfaces. While these techniques have been developed more recently than before, they still leave behind some imperfections called "irregularities," including irregularity in appearance caused by variations in depth between different layers within the final product resulting in unevenly colored appearances when viewed under varying light sources (such as sunlight).

Abstract

The invention discloses light blue jun porcelain and a firing method thereof. The light blue jun porcelain is sintered from a green body and a glaze on the green body surface, wherein the glaze comprises melilite, quartzite, muscovite, potassium feldspar, asbolite, zinc, tin dioxide, iron oxide, magnesium oxide, titanium dioxide, sodium hydroxide, zirconium silicate, potassium oxalate and spodumene; the sintering raw materials of the green body comprise a main material, a pore forming agent and filler; the pore forming agent comprises fine silicon carbide powder, sodium chloride and soda lime; the filler comprises fine kyanite powder, activated alumina micropowder and bone meal. Silicon carbide, sodium chloride and soda lime are mixed with the main material and serve as the pore forming agent, so that sintered porcelain green body can contain a plurality of open pores, the pores are shrunk obviously by adding the kyanite powder with volume expansion at a high temperature, small pores are formed in the porcelain and on the porcelain surface, combination with the glaze is facilitated, flow lines occur more easily in a sintering process, and the generation probability of the porcelain with the flow lines is increased.
