I did a repair on a 3 mm 18k rope chain. The repair consisted of
soldering on new ends so a lobster claw and jump ring could be
attached. After soldering and attempting to polish the chain came
apart at the ends. The links were not soldered so I’m assuming the
heat of the solder softened the metal making it come apart so easy.
How can one avoid this situation in the future?
