Hi Joe - there's little hope of confirming ambergris form images alone I am afraid and chemistry will be required sooner rather than later. Here is a link to more info about ambergris and this outfit also buy if you have
the real McCoy
Superficially it looks about right for ambergris.
If it is ambergris, it should:
- be waxy
- be smelly (the actual odour can vary)
- float on water
- melt readily, to a yellowish liquid
- produce a white vapour at 100C (so put some in rapidly boiling water and see...)
You can also follow the testing advice here
(yes, that spelling is correct for the domain name; the French spell it that way)
Lots of refs out there, eg.:
Let us know!
I have also discovered a similar rock along the beach and was hoping you could tell me if you managed to confirm whether your rock was indeed ambergris and how you did this.
If you feel uncomfortable replying to this post I am more than happy to give you my personal e-mail to message in private.
The presence of squid beaks is the best identifying factor though they are not always there. There are a lot of sea formed lumps of oils/fats that mimic ambergris but this site has the best information with the option fir testing and sale; http://www.ambergris.fr/identification_of_ambergris.html
