How to get red, orange, and pink patinas on copper, using just a torch and Borax.

Please read the instructable for more safety information, and DO NOT attempt this if you are not familiar with your tools and used to working with torches and hot metal. Proceed at your own risk.
In this video I use the most basic tools: a propane blowtorch and Borax. You can get red colors with propane only on relatively small pieces of fairly thin metal. Better red colors come from fast heating. If you have access to a hotter torch such as acetylene or oxyacetylene you can get much more vivid reds, and can get reds on somewhat larger masses of metal.
