I was wondering if I can substitute the creme brulee torch for a butane lighter, the small ones that are used to light cigars. It goes up to 1300 degrees C. An example is this one: http://www.dealextreme.com/p/jet-1300-c-butane-lighter-1320. Basically its a mini torch and unlike a normal lighter, it spits out a jet flame much like the torch. My main concern is if the butane inside it contains any other chemicals residues other than butane that could make one sick or worse. Is it pure butane in these lighters?
