Alabaster is a soft stone
that has been used for thousands of years for carving and shaping into
artistic and utilitarian objects. It is also known as gypsum or hydrated
calcium sulfate that formed with heat and pressure from the deposits of
calcium rich shells and skeletons of sea creatures over millions of
years. The stone has a translucency that augments the variety of colors
and patterns that include white, pink, green, red and black colors that
result from other mineral impurities. The appearance is enhanced by the
naturally occurring cracks and fractures that occur in the stone. The
majority of the alabaster used in my creations comes from Colorado. Each
project starts from a block weighing up to several hundred pounds. It is
initially cut and shaped into a rough cylindrical form using a
combination of hand tools and electrical saws and grinders. The piece is
then mounted on a lathe using a pin chuck and a variety
of scrapers are
used to rough turn the outside shape. The stone is then stabilized by a
process of using a vacuum system to pull a
dilute solution of polyvinylacetate glue into cracks and fissures.
The subsequent hollowing
process on the lathe determines the thickness of the walls and the
amount of translucency that the finished piece will have and establishes
surfaces for final carving, texturing or the addition of wood rims.
Extensive sanding with
grits down to 2000 results in a highly polished
surface that is
then cleaned with mineral spirits and a oil or varnish
finish is applied, followed by a buffed wax finish.
The cutting and turning
processes are very dusty and require good safety equipment including
eye, ear and lung protection.
I have been interested in three dimensional art as long as I can
remember and developed an eye for spatial relationships many years ago.
My earliest work was done in wood, producing various styles of carvings.
Wood remains one of my favorite media to work with due to its huge
variety of colors, textures and ease of working.
I have been working
with alabaster over the last several years and love the feel and look of
the finished product. The colors and translucency of alabaster makes it
a wonderful media for turning a range of vessels that can be further
carved, shaped and textured to result in one-of-a-kind creations. The
combination of alabaster with wood leaves unlimited opportunity to
explore. |
