Driving water out of crystals are crystallization process.

The piece of equipment used are evaporating dish.

Explanation:

Crystallization process

Crystallization is a process of converting crystalline solid state into liquid state. It works both in purification and separation step. Steps involved in the crystallization process are  

        a) Nucleation

        b) Crystal growth

It is the oldest unit operation methods. Methods involved in this process are solvent evaporation, slow cooling, solvent diffusion and sublimation.

Evaporating dish

Evaporating dish is a shallow open container. Evaporating dish is used to heat and evaporate solids. It is made by borosilicate glass or porcelain, which is non-reactive and withstand heat from Bunsen burner.  

The law of conservation of mass states that a mass of an object or the amount of matter composed inside an object or thing will not change unless it is added or removed of the matter that is contained in the object itself.
