Technique
The cold working process is not
well known even to many glass experts. Briefly stated, it is step-by-step
material subtraction. First a piece of glass is selected that can produce the
required finished form. From there it is cut into a rough shape with flat
surfaces by use of saws. Then the form is reduced to final shape by rough
grinding; curves are usually generated in this step. Next the piece is ready
for final polishing.
To accomplish this process, special tools and machinery are generally
required. This photo montage provides a window to the process. These images
and brief descriptions are a taste of the many tools and techniques that are
known to the practitioner.

“We are living in the age of
photonics, where heretofore, theoretical knowledge of electromagnetic
radiation (light) is now being transformed into practical, life changing
applications. My work is a tangible symbol of this time."
