I used some of the lacquer and some FFFFg GOEX to prime some pieces of Visco fuse for testing.
For comparison, I replicated an earlier experiment using white glue and FFFFg. The results I got then were not good. At that time I deemed them a failure but I decided to give it one more try.
The NC/FFFFg fuses were made by dipping, coating the wet lacquer with FFFFg, then two dips in lacquer to seal and waterproof the priming. I let each fuse sit for about three minutes between dips.
The others were made using the same method, but using white glue and no third dip.
I drilled a piece of scrap spruce to hold the fuses for the test, then it was out into the sun for a couple of hours to cure. The white heads are the NC coating, the black ones are white glue.
The results for the white glued fuses were, if anything, worse than the first time. The glue/powder mix is, for all practical purposes, fireproof. Only after the slowmatch completely burns away the mixture and gets to the actual fuse will ignition occur.
The NC/FFFFg fuses, on the other hand, ignited instantly. If the match touched the priming at all, it would bust into flames. In fact I'm not so sure it has to actually touch, the heat from the burning match in close proximity to the priming may ignite it before actual contact is made.
I had one of the fuses ignite the one next to it in the board, and they're about 1˝" apart!
I'll have to do some experiments on just how much heat it takes to ignite the priming.
I have this all on video, but it hasn't been edited or uploaded yet (that's a whole 'nuther story...). I'll put up a couple of clips when I have them ready.
I would call this phase of the experiment a success. Usable NC lacquer
can be made from ping-pong balls and acetone. It's not difficult or dangerous, and it does have at least one bona-fide use in black powder artillery shooting. I plan to find others.
