Как делают обручальное кольцо

The tiny tabletop furnace and crucible where the gold for our rings was alloyed (18k gold is 75% gold, 12.5% silver and 12.5% copper).

The mold where the molten metal was cast, forming an ingot the size of a domino but half as thick.

Strips are cut from this bar.

Ta-da! That’s for my ring.

I had a harder job, his ring obviously needed to be bigger, so the strip was longer.

We went through a lot of saw blades. They are so delicate, the smallest misalignment or jerky movement would break them.

Next, the strips go through this press to round off the sharp cut edges.

The strips are bent into a ring using these fancy pliers.

Getting there.

After going through another press to create a good circular shape, the goldsmith soldered the ends together.

Hot!

Next, we sized the rings by hammering them down this tapered pole.

A brutalized ring. I popped the soldered seam a couple of times.

Right size, but still sharp all around.

The goldsmith filing the top and bottom surfaces until the rings can lay flat on both sides.

Smooth on top and bottom, sharp and pointy around the inside and outside.

Next, we filed the outside of the rings to the curvature we wanted and polished them with a wire wheel.

We wanted a hammered finish, so we hammered them.

Using a rounded file to smooth the inside edges of the ring.

The goldsmith setting a small stone in my ring.

This engraving tool transfers the letters you trace on that brass plate to the inside of the ring via a complicated system of levers.

A little more polishing and we’re done!

The gold dust and cuttings are collected in a leather apron that hangs down from the work area and are then reused.
