No worries, Stone - some of mine are actually labeled nitrate and it's a reaction I'm fairly familiar with having burned some unburned gunpowder from contact shots in my day. Remember my job used to be forensic chemist. We used DPA and a match to test particles from clothing to see if they were unburned gunpowder.
Cool didn't know.
