Here is a tip for soldering a fine chain from @dreamsmith.jewelry - “Sometimes we need to solder a delicate necklace that is torn. I like to use a sharpie and draw a line on my soldering block, then I can align the torn ends of the necklace to either side of that line and know exactly where the delicate solder needs to be done, without having to guess (especially after fluxing the solder area, I find it difficult to know exactly where to solder one chain link to the other).” thank you for sharing this with us!! #solderingtip #sharpie #solderingchain
