Litharge

Litharge is a red lead oxide mineral, dimorphous with massicot, and is often found as a crust enveloping an inner core of massicot in a rock base. Linarite is amphoteric - it dissolves equally well in acids and alkalis, and was formerly used to prepare lead salts and plumbates to make rust-resistant paints.
