burning feed

[jk47]

I read you can burn feed and the ash left over shows the mineral content of your feed
Have anyone tried it

You will also need a working knowledge of chemistry, very good chemistry set and a number of chemical reagents then perform quite a number of tests to actually identify what minerals one will precipitate out of the grey ashes.
