Embodiment 1

[0026] A firing process of high-temperature glaze gold in this embodiment, the steps of the process include: batching, ball milling, iron removal, squeezing mud, refining mud, aging, billet forming, drying, trimming, glaze, plain Firing, polishing cleaning, gold printing, glaze firing. The glaze firing temperature is 1050°C, and the temperature control program for glaze firing is:

[0027] From room temperature to 670°C, the heating rate is 433°C / h;

[0028] 670°C—790°C, the heating rate is 120°C / h;

[0029] 790°C—1050°C, the heating rate is 140°C / h;

[0030] After holding at 1050°C for 10 minutes, the temperature was rapidly lowered to room temperature at a cooling rate of 190°C / min.

[0031] Both glaze firing and biscuit firing are fired in electric kilns.

[0032] Rapid cooling during glaze firing is achieved by adjusting the size of the cooling holes or the opening of the kiln door and the use of the chimney alone or in combination. The chimney has a height of 16m and...

Abstract

The invention relates to a firing process of gold in high-temperature glaze, the glaze firing temperature is 1000-1050 DEG C, a rapid cooling mode is adopted during glaze firing, and the cooling rateis 180-200 DEG C / min. The firing process comprises the following steps: blank preparation, glazing, biscuiting, gold tracing and / or gold printing, and glaze firing. Electric kiln firing is adopted. The purpose of rapid cooling is achieved by adjusting the heat dissipation holes, the kiln door and the chimney. By adopting the high-temperature in-glaze gold firing process disclosed by the invention,the firing rate reaches 100% from less than 50%. The glossiness and the vividness of the glaze surface are improved.

Description

technical field [0001] The invention relates to the field of firing ceramics, in particular to a firing process of high-temperature gold in glaze. Background technique [0002] The high-temperature gold-in-glaze technology is to soften the surface glaze surface through high temperature, so that the gold surface is immersed in the glaze, forming a high-temperature gold-in-glaze effect. The formed gold surface is not only bright and smooth, durable and wear-resistant, but also more resistant to corrosion and oxidation. High-temperature gold-in-glaze technology, porcelain and people's daily companionship, will last forever. However, there are many defects and deficiencies in the firing process of the existing high-temperature glaze gold, and the firing rate is much less than 50%, and the gloss and vividness of the glaze are also not good enough, and flow glaze often occurs in the firing process. question. Contents of the invention [0003] In order to solve the above-menti...
