That is interesting! Here's the excerpt from the webpage, "French Ivory is a synthetic material usually composed of pigmented cellulose nitrate and/or casein (CCI Notes 15/3 Display and Storage of Museum Objects Containing Cellulose Nitrate). It was commonly manufactured in the late 19th and early 20th centuries, and looks very similar to elephant ivory. It can even exhibit the intersecting line pattern, although the manufactured pattern is more regular than the pattern found in natural ivory."

So, to clarify, while casein is lumped in with cellulose, cellulose is the only one with line patterns.

I didn’t revisit the sites I’d seen but iirc it became popular in USA in ca 1920’s -‘30’s and there was a patent ownership right issue between US and French chemists over ‘celluloid’ . There is a very old RGL pc listed on the TP with this type celluloid sole.

French ivory was very common a century ago for cutlery handles, and for dressing table sets - hand mirrors, combs, hair brushes.
I have a ca1900 set of pipes with french ivory projecting mounts; the lines are quite discernible, but parallel unlike elephant ivory.
Unfortunately, it is quite flammable and thus somtimes a problem in the workshop.

Celluloid is possibly the best-looking of the old artificial ivories, but its flammability pushed makers to look elsewhere. It was almost completely out of use by WW2, and possibly a bit earlier.

My circa 1905 ebony Lawries have celluloid on them and I absolutely love the look and feel of the stuff. I have a set of pipes on commission coming with that new art ivory that has cross hatched lines in it, I can't wait to see them. It really is amazing what they can do with plastics, resins and other concoctions.

I know Murray Huggins uses that stuff, and I think Roddy MacLellan uses either the same thing or something similar. I don't know if it's the same as what either of them uses, but I've seen a product called Arvorin that's a resin-based artificial ivory that has lines that look quite close to real schreger lines. Whatever is being used, it definitely looks much better than the ugly white plastic that's been prevalent.

If it looks too close to ivory, would a customs official know the difference??(Never having seen the stuff)

If in doubt, a hot pin poked into a discrete spot would tell you. The difference between burning horn and burning plastic is easy to discern.

If you've not smelled burned horn, go to a cattle branding.
