.... Failing this, it is sometimes possible, as a last resort, to use the experimental alloy as its own “crucible” by melting a pool in its top surface with a fine torch or other concentrated source of radiated heat. For constitutional studies at temperatures below the melting point, alloys that cannot be...

... and electrically because components are glued together. A heating source that is good to use for soldering is an oxygen-acetylene torch with proper head size. Copper will work harden when bent or formed. Too much work hardening can cause collapse of tubing. If the copper gets hard to work, it can...
