Glass beads/glass balls

The core material of glass spheres is glass, primarily composed of silica as the base ingredient, with sodium carbonate added to lower the melting point and calcium carbonate to enhance stability. A small amount of colorants—such as metal oxides like iron, cobalt, or chromium—are sometimes incorporated to produce hues like red, blue, or green. Glass spheres exhibit excellent light transmission, a brittle texture (prone to shattering upon impact), moderate hardness, low cost, and no specialized functional properties.

Detailed Introduction

Product Description:

Material: Silicon dioxide (SiO₂)

Diameter: 1 mm to 100 mm;

Accuracy class: G1000

Hardness: HV 500–700 or 46 HRC

Features: The glass sphere is made of glass, with silica (SiO₂) as its main component. ₂ ) serves as the base material, with sodium carbonate added to lower the melting point and calcium carbonate to enhance stability; a small amount of colorants—such as metal oxides of iron, cobalt, chromium, etc.—may also be incorporated to produce hues like red, blue, or green. It exhibits excellent light transmission, a brittle texture (prone to shattering upon impact), moderate hardness, low cost, and lacks any specialized functional properties.

Applications: garment decoration, children’s marbles, checkers pieces, decorative glass beads for scenic displays, festive decorative bead strings, craft ornaments, positioning beads for low‑end equipment, glass beads for sensing in high‑temperature environments, camera lens filter components, and filter glass beads for stage lighting.
