Abstract

The invention discloses a silver alloy and a method for preparing high-temperature transparent enamel decorating silver jewelry by using the silver alloy. The silver alloy comprises, by weight, 93%-95% of silver, and a little of copper, zinc, palladium, silicon and scandium. The method for preparing the high-temperature transparent enamel decorating silver jewelry comprises the steps that firstly, the silver alloy is made into a matrix base which is in a specific shape, the edge of the portion, fired with enamel, on the surface of the matrix base is provided with a flange, the corresponding portion on the surface of the matrix base is filled with a glaze, firing is carried out for 70s to 100s at the temperature ranging from 790 DEG C to 810 DEG C, the matrix base is taken out and cooled, and the high-temperature transparent enamel decorating silver jewelry can be obtained. According to the silver alloy and the technology method for preparing the high-temperature transparent enamel on the matrix base of the silver alloy, a fired enamel surface is high in transparency, good in glossiness and is firmly combined with the matrix base, after high-temperature firing is carried out for multiple times, the phenomenon of the surface chaps and folds cannot happen, and the requirement of inlay jewelry is met.

Description

Technical field [0001] The present invention is a method of jewelry and metal technology, which involves a method of silver alloy and it is used to prepare high -temperature transparent enamel inlaid silver jewelry. Background technique [0002] Enamel, also known as Frang, Fulang, and Fa Blue. It is mixed with mineral silicon, lead Dan, borax, long stone, quartz and other raw materials according to the appropriate proportion.After being made into a powder -like color material, according to the different practices of its enamel process, fill or draw on the body that is used as a tire as a metal, and it becomes enamel products after baking.High -temperature transparent enamel: enamel burned with high temperature melting transparent glaze.In the traditional cloisonne process, the enamel products burned with sterling silver can get better colors and transparency, especially the burning effect of blue glaze.Important method.However, because the texture of the sterling silver is soft ...
