I have used it to create silver jewelry and to attach transistors to electrical components like circuit boards, as well as making stained glass sun-catchers and sculptures.

  • There is soft solder (melting between 190 to 840 °F) and hard solder (840 °F and above), which is sometimes called ‘silver solder‘. When working with high-temperature solder it is often referred to as ‘brazing.’ When a joint is particularly delicate (ie, joining two very small things or a small thing to a…
