Glitter

Recently I've been making up some glitter formulations and pumping these into stars.
I find the glitter effect to be quite amazing but quite difficult to reproduce accurately each time.
Has anyone any information to share on this topic?

It’s a good practice to keep a small log book with details of compositions, procedures and summery of the results so those can be repeated as accurately as possible. Even so, in some cases it will be of no help. For example, strobe is hard to get right even by commercial manufacturer. Lancaster details in his book a conversation he had with a manufacture. He asked the fellow about the factors that create good strobe effect. The respond was something like: “it depend on the day. Some days it’s better and some days it’s not as good…”

I've found that 'over mixing' the powders seriously affects the 'glitter' factor.
Too much mixing and those little 'sparkles' don't appear and one gets a comet. Too little mixing and the star is difficult to ignite even with priming.
From my findings, glitter is one of the most elusive of the pyro. arts to master yet the effect is well worth the effort even if it's only captured once.

With the permission of the publisher of "The Firemaker" (many thanks to Bonnie Kosanke for obtaining it for me) I'm pleased to present a short but rather interesting article on perchlorate glitter (which I previously thought didn't exist...) by Baron Eric Von Baum.

Perhaps it was just me, but that came as a blank pdf file ? I'd sure like to read it.

Most of all, as I read through alanys page today (keep it up guy! great work!!!!) I asked myself what the other glitter compositions are that alany doesn?t mention.
Then this link answered to all my questions!
many thanks,
paul

then to replace with the Sr analog you`de need roughly 3.7g
BaCO3 g/mol = 197
SrCO3 g/mol = 147
hope that helps a little

Can anyone tell me if I could substitute strontium carbonate for the barium carbonate used in Winokur 39 glitter?

I'm curious, is the carbonate added to this formula to neutralize a potential reaction between the aluminum and nitrate? I know many formulas call for boric acid when Al and nitrates are present...
