This is a piece I made for a co-worker as a present to his wife for their aniversary:
|
This side eventually held a stone, but maybe I didn't get a final picture. |
Here are some pictures of the process:
|
prelim sketch of concept |
|
Formed a dome in sterling |
|
Made a belly button shape |
|
I'm looking at you |
| | |
Cut out the basic shape of the heart. Cut your heart out! |
|
At this point I burnished up the heart with the agate burnisher. I was thinking of a flat border, but decided a rounded one would work better and have a softer look. |
|
On the top right, this is the start of the border |
|
I cut a deep v shape to bend the wire down into the top of the heart, one less seem. |
|
made a couple of bezels, one for each side and to fit the curved shape. |
|
little closer |
|
working the wire around and soldering it into shape, sort of a pain, but I'm getting better |
|
marks to try to solder it somewhat straight |
|
stone side |
|
now for some enamel. basically powdered glass. set oven to 1381 degrees and cook until tender |
|
it took a couple of goes |
|
pretty good |
|
depletion gilding - this happened before the enamel |
The
metal is sterling silver. Sterling is an
alloy of 92.5% silver and 7.5% copper.
This alloy was developed in Sterling England and is used because fine
silver (99.9% silver) is too soft for practical use in jewelry. When Sterling tarnishes that is a chemical
reaction to the 7.5% copper. Fine silver
does not tarnish. So, there is a process
called depletion gilding that I use. The
piece is gilded in the sense that the very outermost layer is 99.9%
silver. But it isn’t plated. What has happened is that by repeatedly
heating the piece and subjecting it to a weak acid bath, the copper in the
outermost layer is leached into the bath leaving a very thin layer of pure
silver.
This one turned out pretty good. It is hard to say how long it took because I always work on multiple things at once. I have a short attention span, like my dog Belle.
