Glass bottle materials directly affect product grade | QLT Glass

When many customers inquire about the price of glass bottles, some people may wonder why the prices are different for glass bottles with the same weight and style. In fact, the difference lies in the quality of the raw materials used for the glass bottles. Commonly seen soda-lime glass bottles use a higher proportion of recycled materials in the production process, while the formulas for high-white glass and crystal white glass contain a much lower proportion of recycled materials. Therefore, the price of the raw materials for these types of glass bottles is much higher than that of soda-lime glass bottles, resulting in a much higher price for the finished product. Some people may not understand the difference between high-white glass and crystal white glass.

First of all, in terms of the color of the glass bottles, high-white glass has better transparency and color than crystal white glass, while the color and transmittance of crystal white glass are basically the same as those of high-white glass. The advantage of crystal white glass is that it has a high density and refractive index. The formulas for these two types of glass are also different. High-white glass requires the selection of high-density, low-impurity feldspar and quartz sand, while crystal white glass is mainly made from quartz and silicon dioxide as the main and auxiliary materials, respectively, and then processed. The production processes for these two materials are also different. High-white glass is mostly machine-produced in China, while crystal white glass is mostly hand-produced. The raw materials used for glass bottles are different, resulting in different functions for the products produced.
