Some Basic Knowledge about Cosmetic Glass Materials

Glass containers processed based on glass are widely used in the field of cosmetics and daily cosmetics. They are popular with users because of their high transparency, good feel, and other characteristics. However, there are several kinds of glass materials, and the choice of materials is often linked to the product grade. For example, in the fragrance market, the main material of perfume bottles is crystal white glass, while the more common cosmetics glass in the market is high white.

Material category

Glass is divided into ordinary white material, high white material, ultra white material, and crystal white material. Different material colors can directly affect the transparency and brittleness of glass products. The better the raw materials are, the better the quality of glass products will be. The prices of different materials will be different. The most common ordinary white glass bottle uses more recycled materials (commonly known as cullet) in the product ingredients. The formula price of high white materials and crystal white materials is far higher than that of ordinary white materials. High whiteness glass needs to select fine materials and quartz sand with fewer impurities and high density, while crystal whiteness materials are processed with quartz stone as the main material and silica as the auxiliary material.

Manufacturing process

Glass is formed by melting silica and other chemicals. In addition to raw materials such as quartz sand, soda ash, feldspar, and limestone. The molding of glass products also requires the addition of auxiliary materials such as clarifier, flux, opacifier, colorant, decolorant, oxidant, and reductant, which are processed and formed after mixing, high temperature melting, homogenization, and then annealed.
