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.
