PMC Class Update!

Remember when I took that PMC (Precious Metal Clay) class with Donna Penoyer?  I got my pieces back, and thought I would update you with the results. 

This is how they went to Donna - dry, but not fired.  She fired them at her studio, and when they were ready I went to pick them up.  Unfortunately, she was out of town so I didn't get to see her studio.

This is how they came back to me, after she fired them and polished them.  I asked her to just leave them polished so I could use the liver of sulpher (LOS) on them myself.  They are very very shiny!  It's hard to tell how shiny, because we have not sun while I am writing this!

And here's how they look after LOS and polished with steel wool.  I was slightly worried because I thought, what if I hate them after I used the liver of sulpher?  But I don't, I like them.  It gives a nice colorful patina on the silver if you don't polish it with the steel wool, I supposed you would need to seal it with Ren Wax or PermaLac if you wanted the color to stay?  I any event, I like them.  The tentacle will be a necklace and the odd shell-like construction will probably sit around in a box!

PMC Class with Donna Penoyer

This past weekend, I took a PMC (Precious Metal Clay) class with Donna Penoyer.  It was at the Society for Contemporary Craft here in Pittsburgh, and the class title was Imaginary Sea Creatures in PMC.  I has asked if a newbie could take the class, and was told yes, but it really wasn't a newbie class!  However, I plugged along and thought I'd show you what we did.

 First we started out with an exercise making a PMC tentacle.  We made a form using epoxy putty, and then made a mold with polymer clay.

 We decorated the polymer after pressing the form, and baked it.  Using the PMC, and the putty form, we pressed the clay into the mold.

 This is my rough tentacle, after drying but before sanding.  You can really see how rough it it - I had no idea you had to sand PMC so much. 
 Here's my finished, sanded tentacle.  If I made another one, I think I would use a toothbrush or something to give the areas in between the suckers a brushed metal look. We didn't fire it in the shop, Donna is taking them to her studio to fire and we can pick them up later.  I'll be sure to show you how it turned out.  I'm hopeful!
After that exercise, we got into the class topic...making sea-like imaginary creatures.  She brought a lot of shells, urchins, texture sheets, etc. for us to use.  Here's where being a newbie was somewhat of a challenge - since I had no experience with this at all, I had truly no idea what I was doing.  Donna was very helpful, but probably I should have taken PMC 101 first.  I did do some sketching of things I thought I would make, and here's how it ended up.


 I took molds of three different types of shells, with the idea of using parts of each.
 We made armitures (structures to drape the clay on while drying) and then pressed our clay in the molds and created the piece.


 Here is my rough sea creature.  It did not turn out the way I drew it, but since it was my first time making anything, I didn't really care.  I was taking the class for the experience.
 Here's my sea creature after standing and adding a hole for the jump ring.  This one is a little bit rougher than the other one on the surface, as I'm leaving the texture from the shells.  I wonder how it will look when it's all shiny and silver?

There were more steps than I mentioned of course, but I can't give Donna's class away, now can I?  I did conclude that for right now, PMC is not really for me.  The expense of the clay, and the amount of time required sanding, makes it seem almost impossible to get into.  Perhaps as you get more experienced, the sanding time goes down, and I am sure copper clay has to be less expensive, but for now, I'll just admire things other people make with PMC.

Here's an example of Donna's art, which you can see on her web site.
