Bottle of unknown material

[Brad]

This is one of the bottles I just bought.  I don't actually have it yet but am wondering what it might be made of.  Seller wasn't sure - he said it could be resin.  It doesn't look like ivory and I think it's too opaque to be amber.  Possibly glass?  I couldn't see any air bubbles in the many close-up pictures they had, but I suppose it could still be just plastic.

Probably going to have to wait till you get it ..

Appears to me resin by looking at the pic, but maybe glass... You will be able to tell better when it arrives..

Hi Brad,

How much did you buy it for? Think I saw something similar in EBay and the seller told me it's synthetic to mimic amber.

Cheers,

Hi Brad,
   It actually looks to me like Coral, but I am bad at judging over the Internet.

I paid $16.00, so not much at all.

Both bottles arrived in today's mail so I've taken my own pictures.  This bottle I would guess is plastic, but I don't see any sign of air bubbles.  It's pretty lightweight so I know it isn't glass.  There is what could be a seam from a mold on one side, but it does not go all the way up the side. There is no spoon, but the the top is held tight by a spongy material that looks modern.  This does not have a hole where a spoon shaft would have been.  This I suppose could have been added later to keep the top in place is the spoon was already missing.  There are some straight lines that could be remnants of tool marks. No markings on the bottom or any place else I can see.

Hi Brad,

As others have said, it is hard to judge from a photo. Mould-formed resin is quite heavy, and usually leaves tiny air bubbles on the surface. In the absence of those my guess is some kind of plastic, possibly enhanced with a bit of hand finishing and polishing to remove the seam lines.
