Silica Sand Price Trend and Forecast
About Silica Sand. Silica Sand contains at least 95% SiO2 and less than 0.6% iron oxide. The most common form of SiO2 is quartz, which is mined from hard rock deposits. It is chemically inert and is often white/colorless. However, the color of each sand deposit depends on the variety of minerals and rock detritus that make up the deposit.

How Do You Use Silica Sand Inside A Kiln?
Silica sand, as with kiln wash, will ruin heating elements on contact. Keep the sand out of the element grooves. Do not let the sand spill into the switch box louvers. If you use a fan to lower the firing room temperature, do not aim the fan directly at the kiln. The breeze can stir the silica sand inside the kiln.
