Hello everyone, I would very much appreciate advice., I have soldered some ends onto a snake chain which is to be used for a bracelet, I have then soldered jump rings and a safety chain to one of the snake chain ends and have included in the mix a pair of magnetic catches either end of the safety chain. The problems now begin, I have soldered one of the jump rings that joins the snake end, magnetic catch and safety chain and the mag catch is no longer magnetic, also it is coloured due to the heat process and I am aware that I shouldn't place this in pickle, Fe etc. I am therefore reluctant to solder the second jump ring joining the bolt ring safety chain and magnetic catch. So the questions are 1/ how do I solder the jump rings and still keeping the magnetic catches magnetic 2/ how to remove the fire stain from the silver surrounding the magnetic catch?
