when looking for Theses you can go to the library of the University
the student presented it to as a starting point. If it was strictly
published as a thesis and never as a book, then you are limited to
finding it in the university’s archives from the department into
which the thesis was entered. All I could find on Alibris was " Earl
Krentzin [silver sculpture, Kennedy Galleries, December 2-31, 1969]
a book that seems to be a gallery’s review of his sculptures in
silver for $4.40. You may also try ABE books, librarians often use
this site to find rare books, look up book values and other things
that have to do with the location and appraisal of books. If it was
never published though you will have to rely on the university or a
student or colleague if Mr. Krentzin is not reachable directly
(posthumously)…rer

Nathalie,

The core of hollow objects must be supported to prevent them from
breaking loose and floating inside the design. I have a section in
the following paper that described a method for supporting the core.

If I can be of any further help contact me off line:

Good luck. Lee Epperson

Hollow models require special treatment. The core must be held with
wire staples to prevent the core from breaking loose and floating in
the cavity of the burned out investment as the metal is poured. The
sterling staple and the rod holding it may be clipped off the model
and used in a future melts.

Metal staples must be added to the models as show below. The staple
should be of the same metal as the metal being poured into the mold.
