How do we distinguish glass rod?

The quality of glass rod currently on the market is uneven. How can consumers distinguish it? Here are several main methods:

1. Chemical coating is the key
The glass rod has a certain glossiness on its exterior color, with a certain beige in white, which is the true color of chemical coating. Pure white or with other colors indicates that there are a lot of other substances in the chemical coating or the glue rate is too low, which will affect the alkali resistance of the glass rod. European high-end glass rod will sparkle in the sun, which is the best among Fiber Glass.
2. The quality of Fiber Glass is extremely important
The surface of the glass rod produced by Fiber Glass is very clean, basically without hair, flower balls or other quality points, the warp and weft yarns are woven evenly, and the cloth surface is straight. At present, there are still a large number of clay yarns that are banned by the state in China. The raw materials are made of pure glass. The product has low breaking strength, poor alkali resistance, short life, and great safety hazards.
3. Feel
Fiber Glass has a thick feel, and the cloth surface is flexible (not rigid) and smooth (not rough)
