Burn tests

What you need:

-Stuff to burn
-A lighter
-A safe
place to burn it
-A webcam to show the world the results

It
started when cleaning up the remaining dirty NG from my last synth, seeing how
beautifully it burned, I just had to show it off :)

(All vids are in the
*.rm format, you need realone player to play that)

========================
The first test is a
drop of NG burning.
Check out the vid here (1.4 MB)

A few things that got my attention:

-Very nice flame color (allmost perfect white - maybe a good indicator
of purity ?)
-Even though it is very energetic, it seems to have trouble
maintaining a flame front

========================

Secondly, I tested some NG on a piece of paper, to get a constant
burn rate

Notes:

-The burn rate
decreased dramatically
-The flame got the nice carbon/sodium yellow from the
tissue
-you can't hear this, but I got several small harldy noticable
explosions

========================
Last NG
test, done with artificial light, giving nicer colors.

========================

I had a film can of previous batch black powder near for making fuses
:)

Notes:

-even though it was
very little (0.2 grams max), it blinded my cam
-it made a very nice smoke
donut: outer diameter ~20-25 cm
-it is fairly fast for the home-made stuff
(I'll write procedure sometime)

========================

Aluminized NG burn test
5 parts NG + 2 parts 400mesh flake Al
powder (in other words, heavily overfueled)

Get the vid here (0.9 MB mpg format)

Notes:

-Bright
hot flame/sparks (charred my nail !!)
-Too much fuel (found specks of Al
remaining)
-It still has trouble keeping the flame front ...

Experimenting with the video software also gives a nice still image
