Hammering out the Details

Glad to be back with Gia for a few weeks!  I've been getting rusty in the chasing and repousse department!   We're all working on a design Gia has drawn up for us.  This is what mine looked like after the first go-round of puffing it up, i.e., repousse.   (Definition of repousse:  Raised in relief by hammering on the reverse side.)  


Gia gave the class a demonstration on how to chase the scalloped edges using my piece.  (Definition of chasing:  To groove, indent.)  Chasing is always done on the front of the piece.


On the left is his demonstration, on the right is what I have to do next.  I find it extremely helpful to have his work right there in front of me as I work and try to replicate what he has done.  

I've discovered a technique for getting the copper off the pitch with very little pitch stuck to the back side.  We already know to cover the side of the copper that will be on the pitch with chapstick.  When you begin heating the copper with your heat gun to remove it from the pitch, almost immediately insert your tweezers under the copper from one edge and start to lift a little.  Moving your heat gun around the copper, off it will pop as soon as the pitch is warm enough to loosen the copper.  The leftover pitch is so minimal, you just need to heat it a little with your heat gun and wipe it off with paper towel.  So easy!


Janice, hammering away...


This is what it looked like after I worked on the right side.  Getting there, slowly but surely...


 And this is where I am at right now.  Just a few more adjustments and I'll be done (I think).  Then I have to come up with own design, which is what I should be doing right now.  But that old "homework" mentality never goes away...just when you need to sit down and do what you are supposed to be doing, you end up doing everything else, like blogging!  


Until next time!

The Making of a Cuff Bracelet (Repousse/Chasing)

Before I began my cuff bracelet in silver, I did a demo in copper.  Even though it took hours making the demo cuff, I learned so much and it was well worth the time and effort in order to save me from making the same mistakes in silver.  Gia is a wonderful teacher and was able to walk me through every step of this process.  


After chasing the design on the front of the piece, this is how the design appeared after the first attempt at repousse (the pushing out of the metal from the back side.)


Here we have more definition.  I've done the necessary chasing on the front and more repousse from the back, and it's just about done!



I decided to use a half round wire that will form the outside edge of the cuff.  I then textured the background before cutting off the extra silver around the edge, and filing for a smooth edge.


It's now time to form the cuff on a mandrel, very, very carefully.  I was nervous that I would cause a crease in the metal, so first used a wooden mandrel and then finished with a steel mandrel.


It's finished!  I'm really happy with the results!  Thank you, Gia!

Bewitched by Pitch

Gia has been teaching at Spruill, so I have been able to continue learning Repousse/Chasing, which I am truly loving. It has taken me a few starts and stops to get to this point. My first exposure to Repousse/Chasing was in a four-day workshop with Valentin Yotkov a few years ago (brought here by the Georgia Goldsmith's Group). I thoroughly enjoyed learning this new technique, but the class lasted only four days, and I wasn't quite sure what to do on my own after it ended. A couple of years later Victoria Lansford taught a class and I learned a few new techniques I had not learned from Valentin. But not until I started working with Gia did it all begin to come together. Gia is a true master and makes it all look easy, which, of course, it is not. Here he is showing us one of his own "works in progress."


I recently began an experimental design on copper for a cuff bracelet. I then transferred the same design (with a few modifications) onto sterling silver and am working on it presently. Doing a model in copper beforehand is extremely helpful. The mistakes are made in the copper, not in the silver. The one error I made on this copper piece was taking the design too far to the ends of the cuff, which I have corrected in the silver piece.


We often begin our designs on a "hard or medium" ROMA Plastilina before placing the metal in the pitch, but if there is not a lot of height desired on the design, using only pitch is completely acceptable. Here's is Gia's example of a project he's been teaching the beginning students, this one done totally on red pitch.





This is the design the entire class is working on.   Here we have Gia's example:


This is my final design, which I sawed out of the copper when finished.
