[0004] CN1084834A discloses a method for making Venus glass from gold ore tailings, using gold ore tailings as the main raw material, common cheap raw materials used in the glass industry, and a small amount of additives for forming Venus bases after fully mixing, melting, molding, and annealing Made by using gold mine tailings, the cost is greatly reduced, but the particle size of the formed Venus particles is small, which cannot achieve a good decorative effect
CN1100388A discloses a method for preparing a copper-venus glass mosaic. In the base glass liquid, copper-venus glass particles are uniformly put into the base glass, and then shaped after being pressed. few
CN2139579Y discloses a preparation method of composite colored Venus decorative glass, which is characterized in that high-reflectance glitter is added to the adhesive liquid, and then coated on the glass plate to form shining bright spots on the glass plate, which has excellent Decorative effect, but it only contains gold stars on the surface, it is not wear-resistant, and the use environment is limited by temperature

Abstract

Provided is a preparing method for red copper star scintillation glass. The method comprises the steps of mixing sodium carbonate, cuprous oxide, quartz sand, potash, Pb3O4, borax, sodium nitrate, iron powder, stannous oxide, aluminite powder and fluorite, and conducting high sintering to obtain the red copper star scintillation glass. According to the preparation method, the method of mixed use of multistage reductant is adopted, the defects of over-thick surface oxide layer of a sample are avoided, uneven golden stars on the fracture surface of the sample, low product use ratio and low production efficiency in the traditional preparing method are avoid; meanwhile, the method adopts the crystallization technology of step-by-step cooling, and thoroughly overcomes the defects of big color difference and uneven grain growth during crystallization after temperature reduction and increase of the traditional golden star glass; the method adopts the way of adding copper star source several times, sufficiently ensures the formation of a triangular copper simple substance in the sample, and is good in star appearance effect; the coloring method is conductive to mass production, short in preparing technology time, high in benefit, good in sample star appearance effect and even in color.

Description

technical field [0001] The invention relates to a preparation method of scintillation glass, in particular to a preparation method of red copper star scintillation glass. Background technique [0002] Copper-Venus glass is opaque brown, yellowish-brown, purple-brown as a whole, with evenly distributed triangular or hexagonal metallic copper flake crystals with a size of 0.5-1 mm, or granular crystals smaller than 130 μm, reflecting bright golden yellow. It looks rich and luxurious, similar to aventurine. Copper Venus glass can be carved into landscapes, figures, flowers and other artworks and decorations like jade, and can also be fused in various colored glasses, and formed into different artworks and handicrafts through nesting, just like gold inlaid in it. After irradiation, it produces a dazzling golden luster, giving people a special aesthetic feeling. Copper-Venus glass is also the main material for preparing architectural decorative panels, mosaics and Venus glazes ...
