Summary:
Ever since man first understood fire, he's tried to harness its power into tools designed to melt, weld, and forge metals and other materials. Ancient Egyptians blew through reeds into crude furnaces to achieve temperatures hot enough to melt gold. Colonial American silversmiths used a blowtorch powered by alcohol. By 1910, over 100 companies were producing gasoline torches under the names Vesuvius, Red Dragon, Meteor, Hercules, Hotblast, or Vulcan. When propane began replacing the volatile gasoline in 1925, the device had finally become a reliable, safe, and portable heating tool. Viewers visit Bernzomatic, where the T7000 Instant-On Torch is manufactured at a rate of one torch per six seconds, and Startech Environmental Group, whose supertorch recreates conditions found only at Earth's core.
