Here is a tip for soldering cuff links from @Lydia.tucci - “When soldering the hinged one-piece backs of cufflinks, I use a heat shield such as Kool Tool to protect the mechanism. Going in and out as quickly as possible with the flame. It rinses off with plain water!” Thank you SO much for taking the time to send this! Anyone else using Kool Tool?!? Tell us about it and send me your Kool Tool soldering tips :) #solderingjewelry #solderingcufflinks #heatprotectant #soldering #makingjewelry
