When I did this though I used about 3,000 match heads in a 2 liter pan. The whole bottom of the pan was covered with a paste of chlorate/perchlorate/glass about 4 cm deep when the mixture was at full boil. Never analyzed the mixture though, at least you didn't try and dissolve the match heads in HCl like I did :(

(Red phosphorus is not incredibly toxic, well, unless you boil it in basified water.)

The red phosphorus is usually on the match box' sides, not in the match heads... it probably depends on the brand.
I once scraped a bit off, gently heated in a tube pre-filled with CO2 and got a bit of white P which condensed as tiny drops on the cold areas.
It's too much hassle to get useful quantities but at least I got a glimpse of white P. (the smell... the glowing in the dark... it's >20 years ago but I still remember!)

If the match heads are red, it could be dichromate.
