I may be wrong but I thought you needed acetone rather than methylated spirit for the C.I.A method???
Thank you for your reply's and welcome. I didn't have acetone so I used meths instead it seemed to work fine. I'm drying the Blackpowder in my shed now but if It isn't try by tomorrow could I heat it in a pan just on a low heat so it couldn't ignite but just enough to evapourate the water.
