The result was pretty good but the process was pretty hazardous and there were still problems with moisture in the salt. So taking in some suggestions and with a bit of lateral thinking I decided to try a different method.
I am currently staying in the middle of nowhere away from any shops so I had to use what was laying around. Luckily I had some salt and some chillies, so that was enough for a proof of concept.
Now a quick warning (the first one) - If you live with people it may beneficial to explain that you are in fact making Chalt and that you have not resorted to cooking Meth for money (you will see what I mean later).
The second warning: The fumes from this process are, although I think pretty harmless, quite noxious. I had to abandon my hob top boiling because where I am now there is no extractor and I was choking everyone in the house. I will explain how I tried to get around this during the instructable.
Anyway here it is Chalt 2: "Salt but not as we no it."
