Thread: Ivory or Bone? ...or what?

I'm in the process of restoring an old G. Johnson I recently acquired. Seller had the scales listed as "plastic or celluloid", but they're obviously not. I suspect they're either bone or ivory, but I don't really have much experience with bone and even less with ivory.

I've researched online and looked through most of the ivory related threads on here and I'm, like, 85% sure they're ivory.
They "tink" on the teeth.
They feel colder than the other scales I have lying around.
They're smooth, dense and fairly heavy.
And for you "hot pin" guys, I did even do that on the inside of a scale in the wedge area. It had absolutely zero effect on the scale (smell or otherwise).

Not entirely sure about the Schreger lines though. There is definitely a grain pattern to them, but it's faint (or maybe my partial colorblindness just isn't doing me any favors here with subtle differences).

Anyway, I figured I'd give some of you a chance to ring in with your opinions. Any help would be appreciated. This blade is likely going to be sold once I'm done restoring it, so I'd like to be as accurate and truthful as possible with the buyer as to what sort of scales they're getting. Plus I'd just like to know!

Also, IF they are ivory, what would you recommend for cleaning them? Specifically the inside of the scales around the pivot area. Of course if they're best left alone, I'm happy to do that too. :-)

Pics below. The darker ones are where I turned the contrast way up for you.

Bone


I hate trying to guess from a pic but here are the reasons as I see them from miles away (Not a very good way to do this)

1, Thickness
2. Contour
3. The "Holes" by the pivot in the pics
4. The fact that it looks like there were washers from the marks in the pics


These are just clues I see, if they were in hand I could tell you in less then 2 seconds

Looks like bone

Ok that's cool. Bone it is then. Worth a shot asking!

Appreciate the help.

Yes, as I recall, they were pinned with washers. Just out of curiosity, were ivory scales never pinned w/ washers? If not, was there a reason for that?

No I have seen them pinned with tiny washers too.. You have to look at the clues add them all together and try and solve the mystery..

I have found very few "Set in Stone" rules like that in this hobby, but you do find trends, one thing I can tell you is that the first time you get a set of Vintage Ivory scales in your hands you will never need to ask again..

im pretty sure its bone. thay are very thick and the grain dosent look like the typical ivory.

Bone... for the same reason.

Ivory will feel like a polished finger nail.

The feel and magnification are the tells.
