[QUOTE="Any Jewelry, post: 3752047, member: 2844"]Rub your thumb over it until it gets warm. If it smells of (spoilt) milk, it is galalith or a similar casein plastic. Some people are able to smell a camphor odour when they warm celluloid. I have never been able to smell that. Other than that, visual. If it is an ivory lookalike that has those alternating even bands I mentioned before, it is celluloid. But casein based plastics are always the most beautiful, with a very rich, deep colour.[/QUOTE]
