With a combined mold making and
casting experience of over 35 years, fossil hunters Nelson
Maniscalco and Marty Shemella are highly skilled in
reproducing detailed fossils and skeletons.
They continue to make molds
and castings for museums around the world and more than a few
of their bronze dinosaur skeleton castings reside in the
collections of such notable celebrities as movie mogul Steven
Speilberg and horror author Steven King.
Both Maniscaclo and Shemella
have instructed students in these processes at a Lehigh Valley,
Pennsylvania,
facility which boasts a well
appointed and growing foundry where |
 |
a variety of metals are cast
including bronze, copper, iron, gold, silver
and platinum.Students
fortunate enough to have one or both of these learned men as
instructors learn the finer points of mold making and casting.
Both Maniscalco and Shemella recently evaluated Smooth-On’s
new SORTA Clear™
translucent platinum silicone and both came to the same
conclusion that “it is unlike anything currently on the
market”.
SORTA Clear™
is mixed 10A:1B by weight and should be
vacuumed before pouring over a model. It cures overnight to a
Shore 40A and offers very high tear strength and surprising
physical properties. SORTA Clear™
silicone is good for prototype mold making, making jewelry
molds (lost wax process) and other applications where
extracting an original from the mold is done using a razor
knife and clarity is required to see where you are cutting.
What’s So Special About SORTA Clear™?
According to Mr. Shemella, “I’ve tried a variety of
“clear-cut” silicones including Rhodia and the Shin Etsu
KE1310. The SORTA Clear™
is incredibly strong, but cuts like butter - easier than
anything I’ve tried. It is also very precise, with absolutely
no shrinkage and no distortion. I have virtually no seam
lines, which means no post casting clean up, which saves
time.” SORTA Clear™
trial kits are available from your Smooth-On distributor or
on-line at
