In order to solder a silver piece with many joints successfully we can use three types of solder: hard, medium and easy. These types mean that they have different melting points (1365F for hard, 1275F for medium and 1240F for easy solder).

Which means you will need more heating time to melt hard solder before it flows into a joint. Easy solder will take the least time before it flows.

When you have many joints to solder, you should start with the hard solder. Leave medium solder till the end and use easy solder only for your last joint if needed.
