Firstly, add two solutions of soluble compounds. Eg when making MgCl2, add Magnesium Nitrate and Sodium Chloride, as these two solutions are soluble. Then, mix the two solutions together in a beaker, filter them using filter paper. Wash the solution several times using deionised water, then leave to dry, or place in an oven.
