I'm quoting from memory here as my book is in the shop, but I've made it so many times I'm sure it's right. If needed I'll correct it tomorrow.

If you sub in a slightly coarser Al you will get a really nice hang and delay on the white. I have been tweaking this formula all sorts of directions over the last month, at least a dozen variations. It's a very forgiving mix that you can really play with and the baseline mix i.e. Purrington's formula which is the one I posted here, looks fantastic all on its own. If you mix about 10% meal powder in there it dramatically changes the effect. The white tail all but disappears, and you get a beautiful super bushy fine ember glittering tail that is pure orange almost. I've been trying to get a drippy glitter effect and it's taking some time, but some of the effects I have stumbled onto during my trials with this formula have been amazing. Some, not so amazing. I can tell you right off don't bother adding anymore charcoal to the mix. But German black is a neat effect as is FeTi.
Dextrin binder and pump?
