just had to see how this stuff burned, so
I took one piece and held it with a pair
of pliers and lit it with a match.
Here it is burning.
I timed it and it took about 5 seconds for
the piece to burn from one end to the other.
Like other powders, if it is not confined,
it burns fairly slowly.
Of course, if it is contained in a chamber,
it burns quickly.
