If this is nitrogen tri-iodide, it is very dangerous.

I would be interested in the formula for touch paper as you describe it.
An old Chem.. Prof. here used to make what he called tickle paper which
exploded with the slightest abrasion (very dangerous I thought at the
time.).

Hello everyone:
I just found an old stash of Cenco Touch Paper, No. 77595. A quick check of
a catalog says it is a good source of smoke that doesn't require burning.
Ideal for our Gas Convection Apparatus(77590) and similar experiments. How
is this used and how dangerous is it to store? Thanks for any advice.
