Glass bottle
In addition to good sealing performance and stable chemical properties, cosmetic glass bottles can be used as packaging for various high-end cosmetics. It can be seen that the color of cosmetic glass bottles is very important, which is related to the quality of cosmetic glass bottles. In general, the coloration of cosmetic glass bottles is also called “sulfur carbon” coloring, but the carbon therein only acts as a reduction and does not participate in coloring. The true color is the sulfur. In the glass melt, sulfur coexists with the form of sulfide S2- and iron in the glass raw material in the form of Fe3+. The product of the product of Fe3+ ion and S2-ion is used as a measure of the concentration of the color center, which determines the glass. The depth of the coloring concentration. For cosmetic glass bottles, the quality is not only determined by the inherent quality of the product, but also from the outside, so the coloring process is very critical. In order to be able to control the color of cosmetic glass bottles, we have to consider from a number of aspects, because it is subject to a variety of conditions, from the raw material quality, raw material ratio to the melting of the various links will have a certain color formation Impact. Therefore, in order to control the stability of the color of cosmetic glass bottles, it is necessary to control in many aspects and strictly control the various aspects of the production of cosmetic glass bottles.
