My goal was to create a prime that would reliably transfer fire from a BP based outer prime to a chlorate based star. Step-priming works of course, but I wanted to isolate the sulfur-containing BP or tigertail primes I use from the chlorate or Perchlorate based color cores with a layer that had zero sulfur. The result is my relay prime #3

70 KNO3
15 Charcoal (coarse)
8 fine Al, (blackhead works great)
5 redgum
3 spheroidal Al
2 dextrin
1 boric acid

bind with 75/25 water/ethanol

The math majors among us will see that in fact these are NOT percentages, they are amounts. They came about from trial and error, from adding the spheroidal Al and boric acid.

I've used this intermediate, "relay" prime to transfer fire from a tigertail outer layer to a killler blue core that is a bitch to light. (video to follow soon, ....hopefully).

do you think that the red gum can be substituted with anything?

It's possible that fine shellac or even charcoal could replace it as long as the redgum isn't being used to bind it. Never hurts to try a small batch.

Well someone is full of shit. That makes no sense, and wouldn't work. .2% Al will make nothing burn blue. If anything it might slightly brighten the tail to an almost unnoticeable degree. On top of that, probably not the best idea to be milling aluminum period, even though I significantly doubt you actually did this.

You're almost down to the level of Mormanman in my book.

One of the best substitutes is pine rosin. I've found it to more available than red gum. It usualy comes in chunks, at least if you buy it from a hardware store, so milling is in order.
