          Artist statement         

Every material contributes a unique visual dialogue.
For Glass it is the transparency. As a sculptural material it stands alone: what defines the work is not necessarily dependent on the outside surfaces. Since this interior space is of great interest to me, I have chosen to create sculptures that draw the viewer in.
While experimenting with color, I have previously used silver nitrate and gold chloride to define that inner surface, my current work employs dichroic coating for colors. When the glass is slumped, the interior layers bend to reveal a remarkable variety of light reflection and colors. This causes the piece to change as the viewer moves around it.
 

Technique

The pieces are created in stages with two grind and polish operations and three oven stages.

First the glass is sized in the oven. It is heated to a temperature where it will soften, in a mold that will give the desired shape and thickness. These pieces are ground and polished, then stacked with the dichroic coated ones (previously coated) inserted
inbetween. The glass is returned to the oven where it is fused into a solid block.

After trimming, the block is put back into the oven where it is slumped. This slumping is done by holding the glass off the bottom of the oven. The oven is heated to a temperature that makes the center drop. This pulls the color down causing it to bend.
It also pulls the colors apart to form patterns on the interior surfaces. This will cause the light to come off at different angles, and the color changes as the viewer moves around the finished piece.
Because glass needs to be heated and cooled slowly, each of the oven steps takes a week; thicker pieces (4 ½ - 5 “) take longer.

At this point the oven work is done and the final cutting and polishing begins. The desired shape is roughed out on a diamond saw then it is ground.
First with a 60 grit diamond bonded disc, then with the following sequence: 140, 270, 320, and 600 grit discs. At this point it is polished using cerium oxide.

The entire oven and grinding process may take one month. During this process as much as half the glass is cut off the initial block.


Confetti

 Confetti, once released, all control is lost, and gravity and wind are what it responds to. All associations are by chance, it is in constant flux always moving from what it was to what it will become, always changing, always random, and always different.

I have two approaches to the idea of confetti.
Both involve stopping the process and looking at it the way a camera might record it.
The first approach deals with just that aspect, it is about randomness, being un-orderly. 
The second approach deals with the same randomness, but also with possibilities.
What will it become?
Will it move left, right or down?
From this static state what can it be next,
what are its possibilities?

 

Unfolding

This piece consists of fused and slumped dichroic glass. After slumping, the pieces are cut (the unfolding), and laid to form a pattern. The process is rigid in terms of the preparation, fusing, slumping, grinding and polishing. Conversely, the assembly is approached very loosely.
I have a vague idea of the look I want, but it is during assembly that the piece comes together.
The relationship between the parts is decided.
Tops and bottoms are ground and polished, then attached to the base.
I want the over-all look to be very loose with the relationship of the color holding everything together.
