Ah - As I understand it.....

In this formula the charcoal gives the orange gold colour through incandescence (The Ti will give the impression of yellowing the orange as it imparts white flashes throughout the effect)

The C particle size dictates how long the orange sparks last, and their density in the sky. A large particle will be long lasting but there wont be many of them. A small particle size will yield a shorter burning "firedust" effect which can be more subtle and pleasing, but not very long lived.

The first method will give you particles smaller than 80 but larger than 100,

The second will give you particles smaller than 60 but larger than 80

Both are probably about right for a formula that calls for 80 mesh charcoal - (I'd use the first - Generally formulas give the maximum mesh size), but if you are especially pernickety then find charcoal that passes a 79 mesh screen but is retained on an 81 mesh screen.

Hopefully this post helps......

(What was the formula by the way?)

The 53 year old that was arrested has been released with no charges being brought.

Just saw that two bodies have been found .This is a very very sad day.

I've worked with SP fireworks in the past - I went out to Liuyang with them some time ago.

I heard the bangs and crackles last night, but initially thought it was a show where the FIRE-ALL button had been accidentally hit. It was only when I saw the news this AM that I realised what had happened.

Still no news at this point about the missing person. Sobering ....
