Silica 200 Mesh

200# Silica is a coarser form of silicon dioxide (SiO₂) than 325-mesh silica, often used in ceramics. As with finer grades, it serves as a key glass-former in glazes, aiding in the development of glossy, durable surfaces. The coarser particle size can influence the glaze's texture and melt characteristics, sometimes creating a more varied surface in terms of texture or crystallization.

In clay bodies, 200# silica contributes to the strength and thermal stability of the fired piece. It helps control the expansion and contraction properties of both clays and glazes, aiding in the prevention of defects like crazing or cracking.

Safety Note:

Handling silica of any mesh size requires caution due to its potential health hazards. Inhalation of silica dust can lead to silicosis and other respiratory conditions, making it essential to use protective measures like respirators and proper ventilation when working with this material.
