Elforyn is a high grade ivory substitute material with a high mineral content. It can be processed like natural ivory - carved, turned, milled, etc. It glues well with Cyanoacrylate & Epoxy glues and can take a clear coat finish. Elforyn is chalk resistant, thermo-formable, chips while machining, and can be polished to a beautiful luster if desired. It reproduces all the typical characteristics of ivory with a natural ivory grain structure, and is fluorescent under a black light. Items are sold per piece, not as pairs.
