Many types of horns, antlers, and bones are used to imitate ivory. Examples are hippopotamus teeth, sperm whale teeth, walrus tusk, narwhal tusk, rhinoceros horn, and deer antler. Vegetable products such as palm nuts, have been used as ivory substitutes. Imitation ivory has also been made by consolidating powdered bone and ivory with protein binders such as glue or casein. Other mixtures include shellac filled with chalk and clay. Synthetic resins, such as cellulose nitrate, were specifically developed as replacements for ivory. Some cellulose nitrate imitations were even made as laminates to imitate the layered structure of ivory.
