December 7, 2006, I wrote about creating a Caulder Bead on my blog. I illustrated the process.
The Caulder Bead is universal and it can be used all through out a necklace. It also can be a single pendant for a chain.
Here is a Caulder Bead with a Lampwork Bead placed inside the coiled wire. Open the Caulder Bead a bit and slip in the Lampwork Bead. When you add the Caulder Bead to a piece all you do is run your wire through the Caulder Bead and Lampwork Bead together and create your jump rings. This is just one more way to use the Caulder Bead.
Lets vary the use of the Caulder Bead! Eventually, you will invent your own variations of the Caulder Bead and create other shapes with your name on it.
The Triangle Caulder Bead
Cut 14 inches of 18 or 16 inch wire. Bend or mark the middle of the wire and begin using your flat nose pliers to make this triangle wire bead. 
Continue bending the wire beginning at the end where the wire meets the long straight part of your wire. Use the flat nose pliers and follow the triangle turning at each corner bending the wire to follow the triangle. At each corner turn and begin to follow the next bend. Continue until to get to the center like you did with the round Caulder Bead. Now you start at the other end and do step one toward the center.
You can also use the round nose pliers and make fancy bends with the triangle bead. This is a little more difficult because you need to design the curves so they all fit with each other. This is a wild looking bead! As with the round Caulder you can create a hanger for another bead to hang from.
