Glass is an inorganic material that has been melted at high temperature (above 800 ℃, daily glass is generally melted at 1100 ℃.), and will not undergo chemical changes below the softening point temperature. Above the softening point temperature, it will only soften, melt or decompose without burning.

But glass doesn't burn. The burning we can see is actually the resin material coated on the surface of the glass fiber cloth or the attached impurities to improve the performance of the glass fiber cloth. Pure glass fiber cloth or some heat-resistant coating can be used to produce fire-resistant clothing, fire-resistant gloves, fire-resistant blankets and other products. However, if you contact the skin directly, the broken fiber will cause great irritation to the skin and will itch.
