Glass ball

The core material of the glass ball is glass, mainly composed of silicon dioxide (SiO2) as the base raw material, with added sodium carbonate (to lower the melting point) and calcium carbonate (to enhance stability). Some may include small amounts of colorants (such as metal oxides of iron, cobalt, chromium, etc., presenting red, blue, green, and other colors). It has good light transmittance, brittle texture (easily broken upon impact), medium hardness, low cost, and no special functionality.
