A number of years ago, I soldered a set of barrels with high temp Hi-Force 44 which melts at 650F. That solder had no color or surface indications any different than lead-tin solder.
My point is; there are many many solder alloys out there with all different melting temperatures, most of which are higher than 363F 60/40 tin/lead.
