started out carving a Corn Maiden as I usually would out of cottonwood
root. Once finished, the foundry then takes the piece, coats it
with a wax and makes a rubber mold of it. Once the rubber has cured,
then they support the rubber mold with a plaster backing. This would
be a negative form of the piece. From this point on, that encased
mold will always be used to create a wax model - a positive image
of the piece. From this wax model, they will then coat it with another
form of heat tolerant plaster, and then melt the wax model out of
that casing. This will, again, make a negative of the piece. The
next step is to melt the bronze ingot and pour it into the final
negative casing. After the bronze cools, they will break that heat
tolerant plaster off of the bronze piece. Usually, the piece is
created in several parts and then welded back together. This will
allow the liquid bronze to fill all the intricate details without
too many air pockets. |

This is where our
day began. They are working on several pieces at the same time,
so I was able to photograph the final two steps before the patina.
Here, they are welding the pieces back together.
|
 |
|
|
Then
they will go back with dental tools and grind in any details that
may have been lost with the weld, as well as clean up any areas
that might have been altered during the pouring process. |
|
|
After
all that is done, then they will sandblast the piece. |
|
Once all the oils
from handling the piece is removed, they heat up the bronze to
apply the patina. Check out that bronze ingot that they are using
for a stand. THAT'S AN $80 BASE!!!

The
first layer of black patina is applied. After he brushes the patina
on, he will heat it again. Look at the steam rising off the piece
as he applies the liquid patina. |
|
|
Here he is buffing the black off
the area that will be of a different color. This process will
leave the black in the lines that create the design on the cape.
|
|
|
After doing the cape with a more
natural bronze finish, he then applies the blue on the face, jewelry,
and corn, then seals it with a lacquer. There are two ways to
seal up a bronze: one is the lacquer application, which will always
retain the shine; and the other is with the application of a wax
finish, which will require regular maintenance.

Me, admiring their handiwork, knowing
that I will never have to touch another piece again to have a
finished product.
I can now see the margaritas flowing,
and, of course, a hammock in the back yard . . .

Here's the final piece before the
face is painted on. That's her make-up that will bring her to
life. It will be mounted on a post with a walnut base that will
have a nameplate. It will be complete in about two weeks.
Hope you enjoyed this as much as
I did.
