I keep seeing "solder melting" - and I have what is probably a very very silly question - What about "Hard" solders like Sil-phos or "Hard" Silver solder?  You know, the stuff that takes a Mapp Gas (or Acetylene-air  or Oxy-Acetylene) to melt?  I've always sort of assumed it would be OK with their quite high melting points (Sil-fos has a melting point of 1185 F.  Silver solders seem to range from around 1200 deg to 1800 degs.  Compare this to 361 degs for 63/37 soft solder and 1984 degs for pure copper)
