A trademark for cellulose nitrate plastics. Cellulose nitrate was first used as a plastic in England in 1855. It became one of the most popular early plastics. It could be laminated in various colors and then cut across the laminations to produce patterns of color. It could also be mixed with other materials such as essence of pearl to make imitation pearl. Celluloid was very popular for knife handles for many years. Its disadvantage is that it is highly flammable. Consequently, its use in today’s factories has been severely limited.
