Use straight acetone in the G. Smith Parlon extrusion technique. Prime with Pinball prime, however they are easily ignited with most any prime.
This is a formula I developed from other existing blue compositions. Basically you are burning copper in a reducing and high chlorine environment to produce the proper spectra. This is a stunning, bright blue that is almost equal to ammonium perchlorate blues. I used 200 to 325 mesh copper powder. This composition was optimized to use the Parlon screen extrusion technique developed by G. Smith.
