Currently @ JB-3D

The sculptors are currently working in wax and clay from the model. Wax work in the winter requires heatlamps to soften the material

Bronze @ JB-3D :
|
Today the sculptors
had their first bronze pour of the trimester. Bobby DesPain donned
the bronze pouring gear and manned the 2 man shank and the crucible
ring.

The molds
are carefully removed from the burn-out kiln and set into the
sand pit. |
|
|

| The bronze is
brought to red heat and is skimmed to remove slag (unwanted debris
in the crucible). |
|
|
Bobby checks
the temp of the bronze with the pyrometer. We take the metal
up to 2150 degrees F before we pour. |
|
|
| Bobby and Ms.
Martin lift the crucible out of the furnace with the shank. |

|
The first mold
is poured.
|
|
|

| The pouring team
agrees on a pattern in which to pour so there is no disruption
in the process. |
|
|
The last
mold. Notice the orange glow on the mold to the upper right of
the one being poured. That mold cracked open from the force of
the expanding bronze on a weakened section of the mold. We discussed
re-pouring the mold, but the crack was too large. |

| Michael opens
his mold with an axe and examines his bronze (below). |

|
| This was a particularly
nice pour with excellent detail and minimal defects. The bronze
casts can last for thousands of years and yet record a moment
with such clarity that on a good cast, you can even see the artist's
fingerprints. |

|
| A recent assignment
involved intricate modeling in oil base clay from a model that
consists of a latex sheet stretched over a form such as a nail,
a shell, spoon, etc. We are examining the illusion that sculptors
deal with daily - the implication that there is surface tension
across a form such as skin over bone and muscle or the illusion
that drapery is taut or any number of implied surfaces that a
sculptor must create to simulate an illusion in clay or stone. |

|
Occasionally the
Advanced Sculptors get confused about mixing investment (for
bronze casting molds). Here we see Alex and Bobby demonstrating
their confusion by getting stuck in a bucket of investment. |
