I have a student who has made a sculpture using first layers of plaster
and gauze which she then covered with a layer of plasticine . Someone told
her that there was a material that she could apply to this piece that would
give her a hard, more durable surface... any idea what material she is
talking about? The only thing that I can think of might be fibreglass , but
the normal procedure would be to use the plasticine piece as a model for a
mold as far as I know and then make a fibreglass cast. The piece is not
simple and is about 24 inches high with numerous undercuts. This student is
young and such an involved mold making process might be beyond her
capabilities at this point. Any clues as to the materials / process that
she is talking about would be much appreciated.
Thanks

Alginate would be the best easiest material to resolve this issue. Try
looking for Pink House Studios on line. Pink House sells a whole line of
different mold making materials primarily for plaster casting from life.
The guy who owns the company is named Mark Prent.
I cannot see escaping having to make a mold. I can though see escaping
having to go through the total process of making a complex mold for the
piece.
If you decide not to use the product, at least buy the instructional video.
It will literally blow you away.

Linda,
You might want to check out Chevant on the web. They make the plasticine you
may have used. They'd probably know if anyone does.

How about using the air drying clay that you can get in the stores like
Michaels or A.C.Moore. It works exactly like the clay you fire except it
air dries. It can then be covered with polyureuthane or some other
non-firing finish. Just a thought.

My experience with fiberglass is limited, but you should
be able to lay up a fiberglass skin directly over the
plasticine, though with some loss of detail compared with
the directly-sculpted surface of the plasticine. Use good
ventilation while doing fiberglass. Auto-parts stores
often carry conveniently-sized kits for fiberglass repair
work...an easy way to get starter-sized quantities of fiber
and resin to mess with.
Another possibility...fiber-reinforced stucco or cement?
These are pretty strong even when thin. Adding extra fiber
probably wouldn't hurt, either.
Both these methods would be more successful if the underlying
form could be removed afterward. Plasticine should be fairly
easy to extract, but the plaster could be a problem. I'm not
crazy about the prospect of gooey plasticine and plaster
chunks knocking around inside when the plasticine melts, and
their weight would require a much stronger coating than a
hollow form would.
I wish I could think of something else...I work with
plasticine, too, making the 'originals' (patterns) for my
cast bronze pieces. When the weather warms up, soft 'winter'
plasticines can get awfully soft, and can flow like molasses
in the sun.
