Ive always wanted to work amber, never got round to it.
BUT heres what id do if I was in your shoes.
Id set up a small flame under a piece of metal, preferably stainless
steel and warm the metal slowly with some of the dust on the top. when
it melts? drip some water near it. If it boils or spits then the temp is
above 100 deg C. if it doesnt then youll know its less. Then think about
using some baking ali foil made up onto a small crucible to repeat with
more of your amber powder.
Let us know the results of your trials.
If you over heat it will burn of course..
Chunks of amber used to be pressed in a heated mold and reconstituted into
"amberoid", which was used for pipe mouthpieces, cigarette holders, etc in
the 19th and early 20th centuries. I doubt this would work with amber dust,
though. It's supposed to be possible to use amber dust to make varnish, but
that's a difficult and dangerous project involving hot ether (I've only
heard about this - don't try it at home, kids).
Copal dust, on the other hand, dissolves readily in denatured alcohol, and
makes a varnish a lot like shellac. (One of the tests for copal involves
wetting the surface with alcohol; it gets sticky, while amber is
unaffected.) It might be possible to reconstitute it into chunks by heating
it, but I haven't tried that either. However, it was traditionally used as
incense, by throwing some on a charcoal ember. Your dust should work fine in
this application.]

You could snort it.
