Importance of surface technology of cosmetic glass bottles

Why do most of the high-end skin care products we see in daily life use cosmetic glass bottles? Because after surface processing, the glass bottles highlight the texture and high-end feeling.

Therefore, when choosing a cosmetic glass bottle manufacturer, you must pay attention to the manufacturer’s process processing and expansion capabilities, because the surface processing of cosmetics can easily cause uneven color. If there is a slight deviation in the color, it will affect the overall effect of the bottle. No matter what flaws are placed on the glass bottle, they will be magnified several times.

In general, the coloring of glass cosmetic containers is also called “sulfur carbon” coloring, but the carbon in it only plays a reducing role and does not participate in coloring. The sulfur in it really determines the color. In the glass melt, sulfur coexists in the form of sulfide S2- and iron brought by the glass raw material itself in the form of Fe3+. The product of Fe3+ ions and S2- ions is used as a sign to measure the concentration of color centers, which determines the depth of glass coloring concentration.
