Fusing Fine Silver Rings
by Howard Siegel
TOOLS:
Fusing or soldering board with smooth
surface
Fire brick or an annealing pan
Butane fueled torch or Bernz-O-Matic
propane fueled pencil torch
Tweezers
Open one quart plastic container with water
Optivisor or similar magnifier
Resource: Butane torch from Harbor Freight
Tool, harborfreight.com
TECHNIQUES:
Wire, fusing.
Step 1:
Place the fusing plate on the annealing pan
or on top of the fire brick to lift it from the
surface of your bench to prevent burning
the bench with your torch.
Now that you’ve learned how to make your
own jump rings, Howard Siegel explains how
to fuse them. The rings made in this tutorial
can be used in his Chinese Stretched Knot
Chain project in the Spring 2008 issue of
Step
by Step Wire Jewelry
. Fusing is creating a joint
in your rings, without the use of solder.
Step 2:
Close the fine silver rings so that the cut
edges of the rings are in very good contact.
This is done by over-forming the rings (or
bringing the cut edges of the rings past
each other, carefully pulling them apart,
aligning the cut edges so that they are
even when viewed from the edge of the
ring, and when looking down the center of
the ring.

Fusing Fine Silver Rings
Step 3:
Place the closed ring on the fusing plate with
the cut facing forward. Close all of the fine
silver rings and place them in rows across the
fusing plate with the cut in each ring facing
the front of the plate.
Step 4:
Turn down the lighting in the room to make it
easier to see the change in color of the rings as
they are heated for fusing. Put on your
Optivisor so that you can clearly watch the
joint in each ring as it is heated for fusing.
Step 5:
Light the torch. Start with the ring at the rear
left of the plate if holding the torch in your
right hand. This will keep you hand away from
previously fused rings, and minimizes the
opportunity to be accidentally burned.
Step 3
Step 6:
Move the torch flame in a circular motion
around the ring to be fused until it turns dull
red. Move the flame to the joint in the ring and
move the flame in a small circle concentrating
the heat evenly on both sides of the joint.
If the flame continues to be held on the joint,
the ring will melt completely through, and a
ball of metal will start to form on either side of
the joint. If this occurs, toss it, the ring is
scrap.
Step 7:
Fuse all of the fine silver rings. You will need
30 fused rings to complete the Chinese
Stretched Knot Chain in the Spring issue of
Step by Step Wire Jewelry
. Slide all of the fused
rings off the fusing plate and into the water
filled container to cool them.
Step 6a
In a short time the silver at the joint will melt and
surface tension will pull the molten metal together
forming a joint. As soon as the metal melts, the flame
must be removed from the joint. If the flame is kept on
the joint, the joint area will get hotter and begin to thin
out.
Step 8:
As an experiment, deliberately overheat the
first ring that you try to fuse so that you can
observe what happens when a ring is
overheated. This operation is called fusing, and
creates a joint without the use of solder.
