Metal casting uses
’lost wax' method
By DAVID JOHN
One of the oldest industrial
techniques known is being
uaed on this campus to create
pieces of sculpture.
Metal casting, which has
been used in art for nearly as
long as it has been in
industry, is being taught by
John Kehoe of the art
department to a small class of
art students.
Using a process known as
the “lost wax” method, the
students have produced several
sculptures of bronze and
aluminum. The students begin
a sculpture by creating a full
size wax model of the piece
they would like to cast.
They then “sprue” the
piece. This is the addition of
wax pieces that will create a
channel to pour the metal
into, and a vent that will let
any gases inside the mold
escape and also indicate when
the mold is full.
The finished was model is
then encased in a very porour
plaster, or “invested.”
THE RESULT, now known
as an “investment,” will
become the mold for the
metal as soon as the wax is
removed. The investments are
placed upside down in a kiln
heated to 1000 degrees
Fahrenneit for two to four
days.
The combination of heat
and time insures that all of
the wax has been burned out.
Any remaining wax or ash
could cause gases that would
damage the piece when the
metal is poured.
The metal, usually bronze
or aluminium, is heated to
2100 degrees Fahrenheit in a
small crucible. The liquid
metal is poured into a bucket,
the impurities which come to
the surface are scrapped off,
and a flux is added to make it
easier to pour. The metal is
then poured into the mold.
After the piece has cooled
overnight, the mold is broken
and the casting is removed.
Due to the extreme heat, the
mold sometimes cracks and
leaves “flashing” that must be
trimmed off.
The presence of any gases
will cause either pits in the
casting, or, if enough gas is
present, an explosion during
the pouring that can damage
or destroy the piece.
TO FINISH the piece, the
sprues and vents are cut off,
and the piece is polished.
Sometimes a “patina” or
artificial aged appearance is
added by rubbing it with a
chemical solution.
One of the problems with
using metal casting in
sculpture is the expense.
Bronze costs 60 to 80 cents a
pound, and aluminium runs
30 to 40 cents a pound.
A medium-sized sculpture
about three feet tall can weigh
as much as 100 pounds.

STUDENTS LEARN OLD CASTING TECHNIQUE
Method practiced in ancient world
Ineligible players in
intramurals
By JIM CORBETT
Glen Goodman, SGA
minister to athletics, has
indicted the University’s
intramural program for
allowing allegedly ineligible
players to participate in the
independent basketball league.
According to Goodman,
persons who have lettered in
basketball are not allowed to
play in the independentleague.
Lettermen are ruled ineligible
in the sport in which they
received the award, he said,
Metropolitan
by Article I, Section A,
Paragraph 2 of the intramural
rules.
“Winners of the Georgia
varsity awards shall not be
eligible to compete in that
particular sport,” says the
intramural handbook.
In a letter dated Feb. 7 to
Mike Castronis and Bob
Williams, intramural directors,
Goodman specifically
protested the participation of
a participant who, he said, has
won three varsity letters.
Opera
to appear in Atlanta
Students have a chance to
make early reservations for
the Metropolitan Opera, slated
for May 8 through 13 in
Atlanta.
Order blanks are available
through Ms. Betsy Powell on
the Georgia Center for
Continuing Education staff.
The opera company will
perform “Othello” on May 8,
“Faust” on May 9, “La
Traviata” on May 10, “The
Daughter of the Regiment,”
on May 11, “Fidelio” on May
12, “Figaro” on May 13 (at a
1:30 p.m. matinee) and “La
Boheme” on May 13.
Performances - except the
matinee - begin at 8 p.m. in
the Atlanta Civic Center at
the comer of Piedmont Road
and Forrest Avenue.
The $4.75 rear upper
balcony seats may also be
reserved by faculty and
friends. Reservations should
be made by March 7 with Ms.
Powell in Annex II of the
Georgia Center.
GOODMAN ALSO
produced a copy of a letter to
the directors from Henry Day,
manager of an intramural
team, protesting the eligibility
of two players who had also
won three letters each.
In his letters of reply to the
protests, Castronis said the
Intramural Council and the
supervisors of the intramural
program “were of a
unanimous decision to
continue with the present
unwritten rule of allowing
anyone associated with ihe
University of Georgia as a
student, teacher, or working
personnel to participate in the
independent league.”
Also, Castronis said the
1972-73 rule book, which will
be printed in the summer, will
be changed so that all may
participate in the independent
league.
Further, he said that at a
registration meeting Jan. 10 it
was decided that anyone
associated with the University
would be allowed to
participate in the independent
league.
Goodman said he did not
remember any statement to
that effect being made at the
meeting.
He also said the Intramural
Council consists of people not
affected by the decision to
allow lettermen to participate
in the independent league.
“There is no representative
from the independent league
on the intramural council,” he
said.
Of the rule, Goodman said,
“It’s just not fair. Under this
unwritten rule that he talks
about Ken Rosemond could
bring his basketball team
down and let them work out
(in the independent league)
once a week.”
