Abstract
Silver halide is precipitated in a large excess of a soluble chloride that forms together with silver ions a silver salt more readily soluble than the silver salt of the final emulsion. By precipitation of silver halide in the presence of the soluble chloride used in excess part of the silver chloride is carried along with the less soluble silver halide and may subsequently be converted into the less soluble silver halide.
