YEh i would boil the kettle and fill a pan with hot water.
Take your jars of spice and put them into the pan of hot water (make sure you don't let any water inside the jars.
Then get a third jar and put some naptha in this... put this jar into the water too.
So now you have your two spice jars and a jar of naptha sat in a pan of hot water. The spice will start to melt,
(sounds like its already oily)
Now drop some hot naptha into the spice jars. Put enough in there so that, when you put the lids of you can shake it about and wash all the oily spice off the sides of the jar.
Then pour it out into another dish for evaporating off. I prefer a small desert bowl because its like a lab evaporating dish and easy to scrape.
Im pretty much saying what Acolon said but, how i would do it.
