I usually make them from thin splints of wood sharpened to a point. I then dip them or just the ends in molten sulphur. I melt the sulphur over a gas stove, outside in a tobacco tin but switch the gas off when the sulphur has melted or just before, if it is heated for too long the sulphur will burn (cover with lid switch off gas) so I try to keep the heat down and the quantity small, no more than a level table spoon. Sulphur is available as sulphur or sulphur candle fron garden shops. I first saw/heard about sulphur matches from a display and postcard in the British museum they were more like lollipop sticks with a bluntly pointed end rather than a rounded end. The picture surfaced last year but I don't know where it is now and havn't got a digi-cam to post here anyway.
I use them to demonstrate fire from flint and steel- once you have a glowing ember on the charcloth just touch the end of a sulphur match to it and within a few seconds you will have a blue flame. It saves all that huffing and puffing into a tinder bundle to get a flame.
My chemical dictionary says HAZARD FROM FIRE AND EXPLOSION OF FINE POWDER not from absorbtion however the sulphur dioxide from the burning sulphur is TOXIC BY INHALATION AND IRRITANT TO EYES AND MUCOUS MEMBRANES, I think you will react violently enough with one whiff not to take a dangerous dose.
Once burning it seems to burn very hot SO BE VERY CAREFULL.
I don't expect there is much interested here as it hasn't been shown on the pukey.
