A general term for daily and industrial products made from glass as the main raw material. Glass products are a relatively transparent solid substance that forms a continuous network structure during melting. During the cooling process, the viscosity gradually increases and hardens without crystallization, which is a silicate type non-metallic material.
How to judge the quality of glass products?
Sight: During the formation process of natural crystals, they are often affected by the environment and contain some impurities. When observing the sun, you can see faint and even small horizontal lines or catkins like substances. And fake crystals are mostly made by melting defective crystal and glass slag, polishing, coloring, and imitation, without uniform stripes or catkins like substances.
Tongue licking: Even on the hot summer dog days, licking the surface of natural crystals with your tongue can give you a cold and cool feeling. Fake crystals lack a cool feeling.
Illumination: Natural crystals stand upright in the sunlight, emitting beautiful radiance from any angle. False crystals cannot.
Hardness: Natural crystals have a high hardness, so use crushed stones to gently scratch the jewelry without leaving any marks; If there are streaks left, it is fake crystal.
Glass products have had a certain impact on China's glass manufacturing and have developed a mature set of glass production technologies.
