Glass artists need a very specific mix of alloys in their solder to get a smooth and clean bead on their work. Lead-free solder is ideal for projects that will be handled frequently or worn, or in workshops and classrooms that need to stay lead free. DGS works and gives the finished appearance of 60/40, excellent flow characteristics, runs an exceptional bead and is environmentally safe and easy to use. The DGS melts solid to liquid 415 - 490º F. Sold in a 1 lb. spool. Delphi Tip: Lead-Free Solder should be used when making projects where your skin comes in contact with it, such as jewellery, boxes and kaleidoscopes.
