Abstract

The invention discloses a precious metal snowflake pattern manufacturing method. The method comprises the following steps of heating precious metal at high temperature for multiple times, and rolling so as to manufacture the precious metal into the required specification, and then carrying out acid pickling and electrolysis on the precious metal, thereby forming the precious metal with snowflake patterns. Crystal lattices of the precious metal can be cracked and recombined for multiple times by the method, and the recombination of the crystal lattices is relatively regular, so that the sizes of the crystal lattices are basically consistent, thereby improving the display effect of the snowflake patterns.

Description

technical field [0001] The invention relates to a method for manufacturing snow patterns, in particular to a method for manufacturing snow patterns of precious metals. Background technique [0002] Precious metal materials such as gold and silver are often used to make ornaments, but pure gold and silver jewelry will inevitably look tacky, so special processing is usually carried out. Among them, making snow patterns on the surface of gold and silver materials is a more common method; However, the existing snow pattern processing methods usually use one-time heating for heating. During the heating process, the crystal lattice of the precious metal will be broken and reorganized. However, due to various uncontrollability in the heating process, after reorganization The lattice size will be inconsistent, and the inconsistency of the lattice size will seriously affect the display effect of the snow pattern. Contents of the invention [0003] In order to overcome the deficien...
