The answer is efflorescence

Efflorescence is the loss of water (or a solvent) of crystallization from a hydrated or solvated salt to the atmosphere on exposure to air.
The water, with the salt now held in solution, migrates to the surface, then evaporates, leaving a coating of the salt. Example is Gypsum (CaSO4.
Copper(II) oxide or cupric oxide is the inorganic compound with the formula CuO. A black solid, it
is one of the two stable oxides of copper, the other being Cu2O or cuprous oxide. As a mineral, it is known as tenorite.
