Default cheap solder smoke filter or overkill?
In article ,
says...

Is there a good test to determine what mix a solder is? I came across pounds of
large diameter solder likely from a plumber. Not sure what old leaded plumbing
solder was. 50/50 by chance?



The best easy way it to check the melting point. Heat someting up and
measure the temperature then touch the solder to it. Raise the
temperature 10 deg F at a time . There are charts to tell the melting
temperature of the mixes. Most plumbing solder is the 50/50 mix and
usually too thick to do much electronic work.
