The present invention relates to the technical field of silver product processing, in particular to a method for boiling silver products, the method also includes boiling the silverware after firing. Cook in the mixed solution of acid and water for 3-7min, then polish the silverware. The mass ratio of acid and water in the mixed solution of acid and water is 1.5-5:1. In particular, it is emphasized that during the cooking process, the temperature and time should be strictly controlled, and then polished with a brush. The silver products obtained in this way can better restore the true color of silver, beautiful and generous, and have good collection value. Silver products do not have any chemical residues, are healthy and environmentally friendly, are more beneficial to human health, and have better health value. At the same time, the application also emphasizes that the whitening process should be repeated 3-5 times, so that the silverware obtained in this way has a better color and luster effect. it is good.

The invention relates to the technical field of silver product machining, in particular to a method for polishing a silver product. The method comprises a silver material forming step and a burning step and further comprises glossing and manual polishing of the silver product obtained after burning. According to glossing, the surface of the burnt silver product is polished to be bright, and then manual polishing is adopted to polish the silver product until the effect that the surface of the silver product is free of crack marks, and a mirror surface is formed on the surface of the silver product is achieved. A new silver product surface treatment technology is provided, and through double steps of glossing and manual polishing, the obtained silver product better restores the silver color, and the silver product is attractive and elegant and has the good collection value. The silver product obtained through the method is free of any chemical residue, healthy, environmentally friendly and more beneficial to body health and has the better health benefits.

The invention relates to a decoration panel inlaid with northern red agate. An acrylic board in a certain specification is manufactured, a bottom color is designed and manufactured on the acrylic board, and then northern red agate blocks in different sizes are manufactured by selecting northern red agate in various colors; according to the designed and manufactured bottom color, the needed arrangement way and patterns of the northern red agate blocks are designed; and afterwards, the polished northern red agate blocks are pasted on the decoration panel. According to the decoration panel, the bottom color serves as a bottom surface, and different patterns are arranged and designed by virtue of the natural texture and colors of the northern red agate blocks.

The invention discloses a machining technology for a retro silver cup. The machining technology comprises the following steps of silver ingot stripping and slicing, melting, mold reversing, tempering,plate pressing, discharging, stretching, molding, annealing, pattern pressing, cleaning, retro treating and packaging. According to the machining technology for the retro silver cup, the machining technology is a novel technology researched and developed on the basis of combination of a traditional technology and a modern technology, and compared with the traditional technology, the aspects suchas patterns, lines and modeling are all greatly improved, the technology is suitable for large-scale production, the machining speed is high, the embossment effect is better highlighted, and the silver cup has the retro color and is fashionable, beautiful and exquisite in workmanship. Through the pattern pressing process and the retro treating process, the silver cup is more attractive in appearance and pure in color, the fashion sense is increased, and the good collection value is achieved; and the retro silver cup treated through the method is high in hardness and not prone to being deformed, has no chemical residue, and accords with the health maintenance concept of modern people.

The invention discloses a ceramic underglaze color material, which is composed of the following raw materials: polyacrylic acid resin, hydroxypropyl methylcellulose, N-ethyl urethane, oleic acid, Tween-80, isocyanate and succinic acid Sodium ester sulfonate, silicon dioxide, titanium dioxide, and deionized water. The underglaze color material is easy to load on the green body, has strong adhesion, uniform material color, and can quickly form a film with good peelability, which greatly reduces Difficulty in drawing, the development and use of this kind of underglaze color material solves the problems of uneven material color, inconsistent color tone, time-consuming carving and difficulties in industrial production when preparing art porcelain or porcelain board signboards and other porcelain works. It not only makes the picture of the fired porcelain fine and uniform, and has great artistic appreciation value, but also changes the traditional production method of porcelain, greatly simplifies the production process, and realizes the industrial production of works such as art porcelain and porcelain board signboards, filling the The gap in domestic technology has been filled.
