solder problems

Can you explain why solder can sometimes eat away at the silver where you place it, leaving a slight depression in the metal, before it runs. This was hard solder in particular.

Re: solder problems


Solder will sometimes leave a depression if it is overheated. It is always best to heat the metal so that the solder is melted by this heat and not by the flame of the torch. Solder contains elements that volitize at lower temperatures and they can then leave depressions in the metal you are solering.

Hope this helps,
