Here is a little experiment that i made today :

I put some NH4Cl into a dish.

Here is the residue in the bottom of the dish after the calcination.

The Sal ammoniac after the beginning of the sublimation at a moderate temperature.

The sal ammoniac sublimated of a nice orange/golden color, when the temperature is rised.

The salt can be used for several purpose, like the Menstrum of Kerkring. But there are other kind of use.

Cool experiment Salazius. I think some of your sal ammoniac reacted with the metal frying pan. I would give glass a try or maybe glazed porcelain. They'll be much less reactive I think. I'm looking into purchasing a big glass globe just for this purpose. :)

How hot did you heat your frying pan?

I heated it up with a gaz torch, yes, it reacted with the metal (not so bad in fact ...), Yes too, I'll take a look for non metallic dishes.

I think Fulcanelli mentioned a method about subliming sal ammoniac with silver/gold calx, and it would extract the sulphur. I could be wrong as I can't recall the exact details, but I'm sure I've heard it somewhere.

I do not remember that, i'll ssek into the books. Thank for the info :)

I plan to make some experiment with metals and Salmoniac sooner or later.
