|"My training in lost wax casting
came from my father-in-law, who was a dentist for 40 years in
East Lake (Dr Jesse Ellis “Sam” Snead). Dentists make crowns by
the process of lost wax casting. When I was newly married, he
gave me a pendant he had made and I expressed an interest in
learning how to do lost wax casting. Before I knew it, burnout
ovens, centrifuges and other equipment appeared in my basement.
My father-in-law provided me my earliest training and for a
while I made things using old dental gold. I have taken jewelry
classes at Rio Grande in Albuquerque, NM, at the Birmingham
Museum of Art and also from Esther Lee (The Studios of Esther
Lee) in Roebuck, Alabama. The manufacturing jewelers at Agnew
Jewelers in Trussville, Alabama, also continue to help me.
||"I am an Internal Medicine
physician, Professor of Medicine and Nutrition Sciences, and I
work at the University of Alabama at Birmingham in the Division
of Clinical Immunology/Rheumatology. I am the Director of the
UAB Osteoporosis Prevention and Treatment Clinic and Bone
Densitometry Unit. My research interests are in the area of
folic acid and methotrexate metabolism in rheumatoid arthritis,
osteoporosis and bone densitometry.
along with my professional life, I have a philosophy that to
successfully age it is necessary to cultivate new interests. I
have consciously tried to develop a more creative side and hope
that this will be beneficial as I get older. My vision for my
jewelry or ornaments is generally to make everyday items that I
see around me, but in silver or gold.
|"Lost wax casting is a method
which uses a wax likeness of the object to be made. The object
is placed on a wax rod which is called a sprue. The sprue is
attached to a rubber base and a metal flask is placed around the
||"Plaster investment is mixed and vibrated to
remove air bubbles and is poured over the object and the sprue.
The plaster is allowed to harden and the rubber base is taken
off of the cylinder. The flask is placed in a burnout oven and
the wax is melted out through the sprue channel, leaving an
exact negative of the object to be formed.
|"Metal is measured out based on
the weight of the pattern and the specific gravity of the metal
to be cast. The metal is melted in a crucible on a centrifuge,
and when melted, the hot flask is placed on the centrifuge and
the molten metal is spun into the cavity.
"The metal cools and the sprue is cut off and
the object is finished by hand polishing methods. I often place
my pendants on bracelets and necklaces which I make using the
Viking weaving method."
