Compared with glass, which is harder?

The hardness of coloured glaze is higher than that of glass.

Generally, the density of ancient colored glaze is obviously higher than that of glass and slightly higher than that of crystal, and the hardness of glazed glaze is also relatively strong, which is equivalent to the strength of nephrite. Hardness is higher than glass. But it's too brittle to knock or collide. The cost price of ancient glass is high, and the fine products are worth collecting.

1. Glazed glass, also known as "glazed glass", is made of artificial crystals with various colors (including 24% lead dioxide) (colors are made of various rare metals) and fired at a high temperature of 1000 degrees. Its colors are colorful; Its quality is crystal clear and dazzling.

2. Glass is an amorphous inorganic nonmetallic material, which is generally made of various inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.). ) is the main raw material and a small amount of auxiliary raw materials. Its main components are silicon dioxide and other oxides.
