A silver halide is the chemist’s name for a compound made of the precious metal silver and one of the halogens, which reside in the second from the right column or group, of the Periodic Table. They are "The Workhouse of the Holography Business" according to Nick Phillips. The earliest holograms of Gabor, Denisyuk, and Leith & Upatnieks were recorded on this type of material.
