Del: I must be talking about "pyralin" I guess because years ago it was discontinued by Schaff and American Supply. The reason? It was found to be extremely hazardous when ignited (as I found out). Not only dangerous as in catching on fire but the smoke is toxic as well. Perhaps the term "ivorine" has been incorrectly used by myself and others putting celluloid and ivorine in the same category or is there something else about this I don't know?
