Here is a tip to prevent solder from flowing from @Abilene_Sky - “One thing that I cannot live without in my studio is yellow ochre powder. Mix with water or alcohol to create a paste and paint where you do not want solder to flow. This magical paint has saved me a few times!” Thank you Jessie, I like that you have repurposed a face cream container to store your yellow ochre too. Thank you for taking the time to share with us! As with all soldering make sure you are working in a ventilated area :) #soldering #solderingjewelry #yellowochre #stopsolderflow
