Abstract

The invention relates to a chrome-containing glass component. The glass component comprises the following ingredients in percentage by weight: 70.5-71.8% of SiO2, 7.4-8.0% of CaO, 4.0-4.6% of MgO, 0.1-0.14% of Fe2O3, 0.8-1.0% of Al2O3, 4.6-5.0% of Li2O, 0.07-0.08% of K2O, 9.9-9.94% of Na2O, 0.43-0.47% of PbO and 0.10-0.35% of Cr2O. The chrome-containing glass component comprises the following raw materials, namely, silica sand, dolomite, limestone, albite, lithium carbonate, sodium nitrate, lead nitrate and potassium dichromate. The chrome-containing glass component which is prepared according to the formula is bright and sparkling in appearance, and is particularly applicable to manufacturing of jadeite imitations.

Description

technical field [0001] The invention relates to a glass formulation, in particular to a chrome-containing glass composition. Background technique [0002] Glass is an inexpensive man-made gemstone that can be used to imitate natural gemstones such as chalcedony, quartz, beryl (emerald and aquamarine), emerald, nephrite, and topaz, among others. The glass used for imitation gemstones in gemology is composed of silicon oxide (a component of quartz) and a small amount of alkali metal elements such as calcium, sodium, potassium or oxides of lead, boron, aluminum, and barium. There are two main types of glass used as gem imitations: crown glass and flint glass. The most commonly used components of crown glass are silicon, soda and lime, which are the same materials used to make bottles and optical glass; in addition to silicon and soda, flint glass uses lead oxide instead of lime in crown glass, so it is also called lead Glass. Because the presence of lead increases both the ...
