Cold Sensitivity: Dry and Powdery Sand that does not hold form
-Use and store above 65F
-Sand may become powdery or dry if exposed to cold.
Regenerating Sand (fix dry sand)
-Add a tiny amount of isopropyl alcohol to the sand (ideally via bottle sprayer) and mix well. Generally, less than 1/2 teaspoon Alcohol required for 10lb evenly spread through the sand.
-Always allow alcohol to evaporate completely before attempting to use sand.

Reusing Sand/Black Crust
-Sand is mostly resuable per casting.
-Small amount of black crust is formed around the casting.
-This crust is two parts: 1. Black sand. 2. Grey, "crispy" sand
-Only the grey sand that feels "crispy" next to the casting should be discarded.
