Welding flux used in filigree golden blank cloisonn product and manufacturing method for cloisonn product

Abstract

The invention relates to a welding flux used in a filigree golden blank cloisonn product and a manufacturing method for the cloisonn product. The method comprises the following steps of making a blank, inlaying a wire, installing the wire, soldering, pickling, painting blue, polishing blue, painting bright white glaze, polishing blue again, polishing, plating gold and the like. The soldering medicine powder comprises the following ingredients of 55-60% of gold, 6-8% of sliver, 27-32% of red metal, 4-7% of cadmium and arsenic trioxide which accounts 22-26wt% of above ingredients. During pickling, the soldered gold blank is pickled for three times and pickled for 10-12 minutes each time; and after blue painting, the sintering temperature is 790-820DEG C. The welding flux used for soldering has the advantages of good liquidity, firmness in welding and easiness in welding. The obtained cloisonn filigree has the advantages of preciseness in positioning, abrasion resistance, high hardness and no colour fading. The white glaze varnishing technology and two-time blue polishing are adopted, so that the obtained artware has the advantages of better color and high collection value, is always new and is free from rusting, and the high-level artistic enjoyment of people can be satisfied.
