Assignment:
Your assignment is to design a metal spoon or fork based on an important person from history.
You need to combine at least three techniques you learned in this class so far:
Piercing
Riveting
Soldering
Enameling
Stone setting (hot or cold)

What is Solder?
solder- Used to adhere metal to each other. It is a combination of zinc and silver. The amount of zinc in the solder determines its melting point. When using multiple solder seams in one piece, you need to use different types of solder so old seams don't melt while making new ones.
TORCH SAFETY:
Always wear safety glasses
Tie hair back
Always point torch away from yourself
Make sure there is nothing flammable in soldering booth or near soldering pan
Make sure ventilation is on in soldering booth
Turn gas on from tank to tip and off from tip to tank
Types of solder:
Hard- Highest melting point, should be the first piece on a multi-solder piece that is soldered
Medium- mid level melting point, second piece after hard solder that should be used
Easy - Lowest melting point, the last piece that needs to be soldered should be with soft solder
Types of solder seams:
Butt soldered seam is when two pieces are soldered next to each other. Make sure both pieces of metal fit tightly.
Sweat soldered seam is when one piece of metal is soldered on top of another piece. Solder should go in between the two layers.
How to prepare your metal:
Saw, cut, file, and sand all pieces to 400g
Check the FIT of your metal. Are the two pieces lining up with no space or gaps?
Make sure everything is CLEAN- dirt and oil keep solder from flowing evenly on metal
Flux metal- flux will keep your metal clean and from oxidizing with heat. Paint flux on any exposed metal
Cut solder pieces and place them on the seam that you are soldering. Solder pieces should be TINY. You can tack them on using a little flux on the end of your brush.

Materials:
Torch- A nozzle-like instrument attached to the gas tank that directs the flame.
Flux- comes from the Latin word ”flow”, and refers to the chemical that assist in the flow of solder by preventing the formation of oxide.
Solder- Used to adhere metal to each other. It is a combination of zinc and silver. The amount of zinc in the solder determines its melting point.
Third arm- A stand that holds a tweezer. It is used to elevate a piece while soldering. A ring is used in a third arm when solder the joint on the back.
Pickling solution- This is a strong chemical bath used to dissolve surface oxidation and flux residue from the metal’s surface.
(crock pot)
copper tongs- An instrument used for transporting hot metal to the pickling solution
Mandrel- Tools used to provide a surface against which a softer metal may be formed. The most common varieties are identified by names related to their sizes, as in bezel mandrel, ring mandrel, and bracelet mandrel.
Rawhide Mallet- A soft hammer used for forming metal.
Bezel- A rim of metal that surrounds and secures a stone. They may be of any size and can be either decorated or plain.
Bezel Rocker- The tool used to tighten the bezel around the stone.
Cabochon- A stone of any shape, often round or oval but it is flat on one side. Designed to sit flat into a bezel setting.

Skill Building & Practice Assignment
Bead and Wire Wrapping
Objectives:
Students will explore attaching stones or beads through wire wrapping/Cold connection
Directions:
Select one of the following patterns to try to reproduce.
Pick out the beads or stones that you would like to incorporate.
Hammer the metal flat if necessary.
Bezel Setting Practice - Spoon Ring
Objectives:
Students will review how to solder and make a bezel box
Directions:
1. Cut the spook/fork to desired length
2. Anneal and form it
3. Make and set a bezel box onto the band
4. Set a stone into the bezel box
Finding your ring size (spoon band can be larger and overlap)
Finding your ring size (spoon band can be larger and overlap)
Making a Bezel
Making a Bezel
Making a Bezel.mp4Size the bezel wire around your stone. It is better to have the bezel slightly too small than too big.
Get the bezel wire ends to fit together with no space or gaps, prepare for solder, and solder in the same way you soldered the ring.
Shape the bezel around the small mandrels and check that your stone fits into it. If your stone does not fit into it then you need to hammer the bezel bigger.
4. Sand the bezel down so that it is thinner
5. File the top edge of the bezel thinner
Soldering the Bezel Box
Soldering the Bezel Box
1. Make sure solder surface is flat so that bezel rests with no spaces or gaps onto a piece of sheet metal
2. Clean both pieces
3. Flux
4. Cut small pieces of easy solder
5. Tack them to the ring alternating inside to outside of the bezel.
6. Solder

Finishing the Bezel Box & Soldering it to Ring Band:
Cut extra metal from around your bezel with your saw frame.
File and smooth out the edges of your bezel box
Hold your ring band in the vice grips and file the top of the band flat
Prepare bezel box and ring band for solder
Set the bezel box upside down and the ring band on top of it, help up by the third arm. Solder pieces together.
Setting a Stone
Setting a Stone
Setting The Stone.mp4After your metal is cleaned up put a TINY amount of glue inside where the stone will go and place the stone inside the bezel
Use the bezel rocker to tighten your bezel around the stone
Use a mandrel and rawhide mallet to shape your ring.
Sand, buff, and polish your piece
