The world of glass bottles is a wonderful world. It all starts with the colorfulness of glass bottles. We can see that the liquor bottle is transparent and colorless, beer bottles are green, brown and amber, wine bottles, essential oil bottles and olive oil are dark colors. These different colored glass bottles not only enrich the packaging market, but also meet the special needs of different products for packaging. For example: dark glass bottles can meet the requirements of light protection products such as wine, olive oil and essential oils. Glass bottles also occupy a certain advantage in the market with other material packaging due to their rich and varied appearance. Well, many people have questions about how these colors of glass bottles are made. I believe there are many people who are interested in understanding. In fact, glass bottles often add a certain proportion of manganese dioxide to the glass melt. Different proportions of manganese dioxide will present glass bottles of different colors. Glass contains different metal compounds that are "stained" in various colors. Add cuprous oxide to get red glass. Yellow and purple synthetic white, the glass becomes colorless and transparent. Manganese dioxide is an oxidant that oxidizes green divalent iron ions to yellow trivalent iron ions and manganese to purple trivalent manganese.
