Handmade Jewelry - Spring Term Projects

Totally forgot to post this! In Spring term, yes, I took yet another jewelry making class. It's sad I can't take it again for credit. BUT my teacher, who is so sweet, said I'm more than welcome to come in and work in the fall! I will definitely be making some time each week to go in there to finish my 8 or 9 rings that are still in process, and probably make more!

Song and Photograph of the Week - August 18, 2014

If you're looking for a song that makes you want to dance then Popular Song by Mika and Ariana Grande is one for you! It is super catchy, and upbeat. I have been listening to it quite a lot over the last week. It's been getting stuck in my head!

I changed the photograph of the week from what I had originally planned. I took some photographs of some rings I had finished a couple months ago so that I could list them in my Etsy shop. This is my favorite, mostly because I think its clever! Sun, moon and star! The sunflower is from my family's garden, it is gorgeous!

Handmade Jewelry - Process

The 2 classes I have taken already (Intro to Jewelry making, and Intermediate Jewelry making) I have been focusing on a "loss wax" process. For me, it opens the most possibilities to what I have been wanting to and have been creating.

For this process you start out with wax that you carve, or shape in the designs you want. One wax I use is a tube, and you use a cool shaving mandrel that shaves the hole to the size you want. From there you can carve the outside to be what you want. I also use a lot of wire wax, this wax is in strands of varying thicknesses. I find this to be easiest to work with when making rings that look like branches. :)

Wire wax is the left picture. Carving wax tube is on the right in 2 different profiles.

From the wax you attach whats called sprue wax on the bottom of your piece, usually 2 or 3 pieces of it. Then you mount that onto a rubber base that has a metal cylinder that fits onto the base. This is for the investment (like plaster) that you mix water with it to make (slightly thinner than pancake batter). You pour that into the cylinder mounted on the rubber base, and tap it on the counter to get the air bubbles out. After that, you let it sit 10 minutes before carving your name and I like to put what project it is that's in the mold. After leaving it overnight, my teacher takes the molds, takes the rubber bases off and fires them in a kiln. This melts and burns the wax out of the mold. Hence the name, loss wax.

You start out with the ring you want to put in the investment.

You add the yellow sprue wax, weigh the ring, and then mount it on the rubber base.

Showing you how it looks when mounted,  from above.

With the metal cylinder before and after pouring the investment.

After the mold is burned out, you can then cast the ring/jewelry. The way you do that is on a centrifuge type contraption. You mount a crucible on an arm that spins after winding up and releasing it.
 

But first you need to get your mold hot again. Usually 400 degrees F is enough to get really good detail out of your mold. When your mold gets hot enough, you mount that on the arm along with a crucible. Depending on  the metal you should get the crucible hot first. In my class we use a large torch. Once the crucible is hot, you add the metal and flux (keeps the metal from oxidizing). Melting the metal can take 10 minutes for silver, you have to get it to where it is liquid. Silver melts at 1,763 degrees F, so you can see that is very hot. Once the metal is liquid, you release the wound up arm, and it spins the whole thing around very fast. In doing so, the liquid metal is shot into your mold. Once your mold and crucible spin slow enough that you can stop it, you take the crucible out and set it on a firing block, so it doesn't burn the table. Usually 5 minutes is enough for the mold and metal to cool enough to quench it.

Once the mold is cool enough (not glowing), you take tongs and submerge it in a bucket of water. I usually use a butter knife to dig my pieces out of the investment. Unless the mold is still quite hot, then the piece usually boils out of the investment, making my job a lot easier.

This is what you end up with after digging the (now metal) piece out of the investment.

After cutting off the sprues (now in metal) you have a lot of work to still do!

Now you have a piece of jewelry! But your work is not over yet! You then have to cut the sprues off your piece (which are now metal). Then you have a lot of post work to do to clean up your jewelry! Filing, sanding, and polishing are just some of the things you still need to do to your piece.

Handmade Jewelry - Fall and Winter Term's Projects

As some of you know I have been taking Jewelry making/Metal smithing classes at Portland State University. Since I switched to a new major (Arts and Letters, which is a general degree) I am taking the jewelry making classes to help satisfy upper division credits. The last 2 terms Ive been taking the classes. I wanted to share the pictures I have been taking of the finished products. I am in love with the process of making jewelry.

I thought some of you might want to see a little into what I do when I am not working on business stuff, shooting sessions and editing.

I am a little obsessed with making rings. Until now, I have not been a big jewelry person, and didn't used to wear it a lot. Now, I am able to wear my latest rings! My goal is to be able to sell what I make, and have been getting a good reaction from people that see them. If you are interested in how I make them you can read my post next week!
