The first solder was made and used sometime before 4000 BC.

Yes, usually no problem. If you know how to solder, then solder away.
In some solder it is. But even if it is in the solder you should still use flux.
both are metals
Solder is not a true solid because solder is a liquid but during the art of solding it changes into a solid.
soft solder is made of tin and lead. :D
solder and iron
A reel of solder used for joining electrical circuits together on circuit boards. Solder is made of a mixture of tin and lead and sometimes has has flux (a form of acid) in the core of the solder to ensure a clean surface for the solder to flow into.
Solder
Plastic, solder, and resistors.
Traditional electronics solder also contains resin.

well wetted round both conductors, and will appear shiny and smooth.
Shouldn't, most of it is still made with lead.
Made without Lead solder.
A Conductor, SOLDER IS NOT AN INSULATOR. The most common types of solder are made of tin and lead. Another type is silver solder. All of the materials used are metals and are good conductors of both heat and electricity. If you solder something you would notice if you ever held a wire (without protection) while applying solder to it your finger would probably receive a burn (speaking from experience).
