Here is a post soldering tip from @baystateopals - “Even the most experienced jeweler sometimes has solder that doesn’t flow completely when soldering a bezel to a backplate. It can be difficult to see where more solder is needed. We use a flashlight with a pointy tip and shine light into the bezel. This illuminates the gaps to show where to re-solder. When no more light shines through you are done!” LOVE this Lou! Thank you for sending. #bezelsetting #solderingbezels #jewelryfabrication
