What is Silica Dust?
Silica dust consists of tiny particles of crystalline silica, a common mineral found in the earth’s crust. In ceramic and pottery manufacturing, raw materials like clay and flint often contain high levels of silica. Activities such as sanding, drilling, or milling these materials release silica dust into the air, which is hazardous when inhaled due to its small particle size and chemical properties.
- Common forms include quartz, cristobalite, and tridymite.
- Particles smaller than 10 micrometres lodge deep in the lungs, causing long-term damage.
- Exposure risk varies depending on manufacturing processes and control measures.
