Next we will turn the ingot into usable 1/2 round wire using a
rolling mill. This is a combination mill, meaning I can roll wire and sheet with it. You can see the ingot on the left side between the square wire slots.
Roll it out until you get the diameter to what you want for the ring.
A tip on using the mill. Flip the piece end for end every time it goes through the machine.
Once you have the right diameter move over to the 1/2 round rollers on the right side of this machine.
Now we have a nice, thick piece of 1/2 round. You can see how much it has stretched out in the mill. There is a small flaw, seen on the bottom of our wire. It won't effect the end product and can be filed off at any time.
This piece is work hardened at this point and is far too hard to shape. Let's anneal it. Dip it in boric acid
fire coat, lay it on a
charcoal block and hit it with the torch. Get it red hot, use even heat util it starts to glow, keep the heat on heavier wire like this for 20-30 seconds. Once cool place it in
pickling acid.While the wire is in the pickle we'll form a bezel for the garnet. In the picture is bezel wire, you can roll a piece of your ingot out and anneal it for a bezel too. Typically bezel is 28-30ga and the stuff you buy is usually pure silver, not sterling. Just wrap the bezel around the stone and mark it where it meets up. Cut the bezel and file the ends smooth.
Make sure the ends fit tightly together and solder it. We will be using three grades of silver solder, hard, medium, and easy. Flow points for these solders is 1450,1360,1325 respectively. This means we can solder on top of other solder joints without re-flowing them by using solders with a lower flow point.
Here is the bezel, ready to solder, with a bead of hard solder on top of the joint.
Always solder by heating the metal around the joint, NOT THE SOLDER. Get the metal hot enough to flow the solder.
Now this goes in the pickle as well.
