Yellowish Orange Glass Snuff Bottle

A most interesting snuff bottle! I had to do a specific gravity test on it to determine it was glass because it felt warmer, not cold like glass. It has a specific gravity of 2.6
So the feel of it, and the color both have me still curious. There are definitely tinges of red in this bottle, which give it an overall yellow-orange color and you can see in some places where the red is more prevalent.
The first picture is a good example - the bottle is yellow in bright light, and then gradually turns to orange then to red in the shade.
Also the neck on this on slopes down to the cavity which I read is a good sign that the bottle is older.
I will do more investigating on this fascinating bottle and report what I find!
