Problems solved by technology

[0005] Chinese patent CN109808394A discloses a production process of high and low temperature enamel metal ornaments. The disclosure date is May 28, 2019, because the color of high temperature enamel will have different rendering effects on different metal tires, such as blue-green on 9K yellow The expressive power is better, but the expressive power of red and yellow is slightly worse. This process uses the color of low-temperature enamel to make up for the color defects of high-temperature enamel on different metals, and solves the problem of poor color expressiveness of existing enamel products. Through high-temperature and low-temperature glazes Color separation is carried out separately to obtain enamel metal ornaments with stronger color expression and richer colors, but the process operation is complicated, and it is not given that direct burning at high temperature on K gold will not cause enamel to be affected by the background color of K gold. The solution to the chromatic aberration of the glaze

Embodiment 1

[0036] Such as figure 1 As shown, according to the embodiment of the present invention, the process of burning out the enamel color not affected by the background color of K gold on K gold includes the following steps:

[0037] S1 uses a K gold sheet with a diameter of 2 cm and a thickness of 0.8 mm as the base tire. First, use a colorless transparent glaze (a glaze specially used for gold bases, which is available in the market) to make a uniform base. After sintering in an electric furnace at 815 degrees Celsius for 50 seconds, check whether the entire metal surface of the gold piece is completely covered by the glaze. If there is exposed metal, you need to repair the glaze again and sinter the glaze again at the same temperature and for the same time. Check again after the gold piece is cooled to ensure that the metal surface of the gold piece is completely covered by the glaze, dip a little water with a brush to coat the surface of the glaze, and then paste a layer of 0.02...

Abstract

The invention discloses a process for firing an enamel color unaffected by a K gold ground color on K gold. The process comprises the following steps of conducting bottoming by using colorless transparent glaze, and pasting a layer of silver foil after sintering; conducting sintering again after the silver foil is pasted, so that the silver foil can be tightly attached to the surface of the K gold; checking the fitting degree of the glaze and the silver foil to ensure that the silver foil is sintered again under the conditions of no bulge and no dislocation; and checking the fitting degree of the glaze and the silver foil again, and dispensing enamel glaze after it is confirmed that the glaze and the silver foil are completely fitted. According to the process for firing the enamel color unaffected by the K gold ground color on the K gold, pure-color enamel, various light-color enamel and all design schemes needing to be transited from transparent white to colored enamel are successfully fired in a local silver foil applying manner; and by adopting the process, the pure blue enamel can be fired, so that the problem that the blue enamel is greenish is solved, the technical problem that the enamel is used as high-grade jewelry is solved to a great extent, and the expression form of the enamel is enriched.

Description

technical field [0001] The invention relates to the technical field of high-temperature enamel, in particular to a process for firing enamel colors on K gold that are not affected by the background color of K gold. Background technique [0002] Adding the word gold before jewelry is often labeled as middle-aged and elderly people. Gold jewelry looks earthy and tacky. The only words associated with young people may be gifting elders, sending relatives and friends.
