Ivory hilt dagger with "Tears" and a "Smiley?"

[Mare Rosu]

Spiral:
Sir, you are most correct, knowledge is a great power and you have supplied me with a lot of power from your excellent postings on Ivory. I did learn a lot from the hands on inspection from the handle material folks, but your posting were far more informative and technical. Showing me a picture I took and explaining what was in the picture. Information that I did not know was there, until you pointed it out, hard to believe!

Rand;
Thank you, as well, for the information about the material on my dagger handle, your "leaning" was right on. Do you think we could get Spiral to start a thread on his ivory knowledge, as you suggested? He said he is just learning about ivory, fine, I will take anything he offers. How about it Spiral, PLEASE!

Jens:
I do need to get out of the house occasionally ( not just to the doctors office! )
Again you have helped me in my never ending quest for knowledge.
I have acquired the name of my dagger, how the little balls were placed in the hilt, and what they were for, what the handle material is, also where it was probably made. Not bad, not bad at all.
Only thing still unknown to me is what was the "smiley" for?

I think I/we have "beat" this dagger to death with all the information from all the good folks, posting, on this forum. It is always amazing, to me, the collective knowledge/power that is shown by the forum folks. It has been a great "ride" for me and I thank you one and all for it.
Gene.

Glad it was of some use Gene!

I think the total of my ivory knowledge is just about exhausted though., as I said I am just a mere student, 6 years ago I couldnt tell bone from Ivory. so I set out to learn a little more than the often reapeted antique dealers old wives tales I kept hearing, that are sometimes so misleading. So I both read & also more importantly spoke to instrument makers who buy & use the various types every working day of there lives.

But thankyou for asking.I am flattered.

But sure after a little more research on my part perhaps I can add more of substance at a later date.

There is one other note for the coloring of ivory. As Spiral says it depends on environment and one environmental factor is the amount of exposure to sulfur.

Sulfur is mostly what colors ivories. For example elephant ivories in the presence of sulfur will turn yellow to orange to brown. IT is always in the air, but heat will accelerate the chemical reaction as the ivories "breath" in the sulfur already in the air.

By the way, Jens I always love your pictures - and am insanely jealous.

This is well handled white African ivory. Mangbetu/Zande - South Soudan, North East Congo.

I have a vague remembrance about that the Moguls used Sulphur in the water to cool it (Beriner?) – did they?

Battara; Great information about Sulfur changing ivory yellow.
I know for a fact, unfortunately, that rubber bands have a lot of sulfur in them, and I assume all rubber products also has sulfur in them. The rubber bands were stored in a box with some of my old Silver coins and the coins turn black
Question, Battara, on this dagger as well as others daggers/knives that I have with ivory handles I use Renaissance Wax on them, will that protect them from the effects of ambient sulfur?

Here is some info on identifying ivory types.

First: Sorry about your coins. Sulfur also reacts with silver to make sulfur oxide on the silver - also known as tarnish. This also happens on copper to produce copper oxide which is green (and poisonous) (lots of copper in brass and bronze).

Second: Renaissance Wax will protect them since it seals the ivory (also wood, steel, etc.). A very good question.
