In my metalsmithing I class (I’m a newbie to the world of soldering)
we use copper and brass. We use silver solder and it works great on
both metals. We had to practice butt joints, T joints and sweat
joints on copper (silver solder) before moving onto our current
projects, rings made of brass. We saw and file the top layer of 22g
brass and solder that onto 20g brass. Oncethe flat layers are
soldered together, the ring is shaped and the edges soldered
together. That’s where I’m at now - going to reshape, sandpaper and
patina it next Monday.
Our first project was a sawn and filed brass pendant - I made a
fairly intricate Egyptian Eye of Horus triangular pendant. The ring
has hieroglyphics on it so I’m firmly in an Egyptian frame of mind.
