FloridaCracker Posted November 11, 2015 Posted November 11, 2015 I recently got a box of matches from a company I've never heard of before called UCO and made in Chile. On the box it states that the top contains perchlorate. The strike composition is white. I have tested quite a few compositions for sensitivity and haven't got reactions from hammer on steel impact, and steel on steel friction. Replacing the perchlorate with chlorate I got some small pops but never got the entire pile to go, even with sulfur or antimony. Anyone have any idea what could be in the strike composition that is white and sensitive enough to ignite with some friction? I could see chlorate working but curious about what would work with perchlorate?
Mumbles Posted November 11, 2015 Posted November 11, 2015 Some of the reviews mention a "phosphorous" odor. I'm not entirely sure what that means, but it could mean there is phosphorus sesquisulfide in the composition somewhere. It's not quite white on it's own, but mixed with potassium perchlorate or chlorate, glass, carbonates, and some of the other standard things the overall composition might be. P4S3 is kind of yellow to gray depending on source and purity.
