There are lighters out there designed to burn up to 2500 degrees Celsius, so it is certainly possible to find one that is up to the task if you have a project that involves melting glass. One reason that most lighters will not melt glass is that they are simply not hot enough.
Best Answer: in the revolutionary war camp fires burned hot enough to melt lead for the soldier's muskets. lead melts at around 800F. my camp fire burns hot enough to melt aluminum, which is at least 1150F. I like lighting my fire the easy way. 1/2 cup of gasoline (or extremely flammable oil) and drop a lit match in to get a nice big, roaring fire. this gas or other fuel I add makes the fire burn hotter.
