Filigree enamel silverware and manufacturing method thereof

Abstract

The invention relates to the technical field of silverware manufacturing processes, in particular to filigree enamel silverware and a manufacturing method thereof. The manufacturing method for the silverware comprises the following steps in sequence: preparing a blank, whisking, filigreeing, welding, dispensing a blue pigment, and grinding the blue pigment; the step of dispensing the blue pigment comprises the following processes: filling a pattern which is formed by silver wires on the surface of a silver blank which is welded in the step (4) with glazes, then performing high-temperature sintering, namely, sintering a low-temperature glaze for 3 to 6 minutes at the temperature of 710 to 790 DEG C, sintering a high-temperature glaze for 2 to 5 minutes at the temperature of 780 to 830 DEG C, and repeating the processes of filling the glazes and sintering for 3 to 4 times. The filigree enamel silverware provided by the invention is attractive in appearance and colour, long in storage time and wide in spreading degree; colours are rich and are not single. The manufacturing method for the filigree enamel silverware provided by the invention is easy and quick to operate, and is suitable for industrial popularization.

Description

technical field [0001] The invention relates to the technical field of silverware manufacturing technology, in particular to a cloisonné enamel silverware and a manufacturing method thereof. Background technique [0002] The disadvantage of traditional silver jewelry is that the color is incomplete, and the color appears as a single color. Silver jewelry is mostly silvery white with a slight yellowish tint, showing a soft metallic luster. Because it is easy to oxidize, the color will turn into a dark yellow-white after a long time. Silver is a relatively active precious metal, which can easily react with sulfur or hydrogen sulfide in the air to form black silver sulfide. This is why silver jewelry will turn black after use. The silver jewelry that has been used for a long time is rarely rubbed on the surface, so the blackening and blackening phenomenon is more serious after being placed. Silver jewelry needs to be cleaned after being worn for a long time, which is labor-...

AI Technical Summary

Problems solved by technology

Although these methods have eliminated the appearance of green rust spots to a certain extent, there are still many deficiencies, mainly as follows: 1. Compared with the display, the tin hanging treatment on the inner wall can delay the appearance of green rust spots to a certain extent, but General daily necessities need to be used frequently and need to be washed and wiped. With the increase of the number of times of use and wiping, the tin layer on the inner wall of the cloisonné vessel is easy to wear and fall off, exposing the copper carcass and producing rust spots, which is not beautiful. It is not safe; 2. The tinning treatment on the inner wall of cloisonne products must be carried out after glaze filling and roasting, otherwise the tin will melt and fly during the roasting process, and tinning after roasting cannot guarantee the narrow space of the inner wall of the appliance, such as the inner wall of the spout 1. The bottom corner of the inner wall of the copper tire is completely hung with tin; 3. When the inner wall of the copper tire of the cloisonne products used as daily necessities, such as tea sets or tableware, is glazed, it is not only too ugly from the perspective of technology, but also makes art invisible. The value is greatly reduced, which affects its market price. The key is that the glaze hanging treatment cannot guarantee the complete glaze hanging on the inner wall-because the glaze hanging system is operated with the furnace door open, the roasting residence time is short or the rotation speed of the vessel is uneven. , the rim of the vessel, the neck of the inner wall of the vessel or the bottom foot of the vessel, and other parts with a diameter smaller than the waist of the vessel will have copper exposure, which is very dangerous

Due to the above reasons, the market for cloisonne products in the field of living utensils and handicrafts has not been opened for a long time.
