The 4mm Precision Clear Glass Ball from Taian Porei Import & Export Co., Ltd. is manufactured from soda lime glass with a diameter tolerance of ±0.02mm, ensuring high precision for industrial and decorative applications. The composition includes 72% SiO2, 15% Na2O, and 9% CaO, providing a balance of durability and optical clarity. With a specific gravity of 2.6 to 2.8 g/cm³, these glass balls are suitable for use in a range of environments where consistency in size and material properties is critical.

Soda lime glass balls in this size range are commonly used in applications such as reflective road markings, decorative lighting, and precision instrumentation. The material’s typical hardness of 5.5 to 6.5 on the Mohs scale makes it resistant to scratching, while its transparency allows for light diffusion in optical applications. Standard surface finishes for such balls include untreated (clear) or frosted, depending on the intended use.
