The tips suggesting rubber compound with catalyst (room temperature vulcani=
zing rubber)-- similar to that which dentists use for mouth work -- now mo=
re widely available are spot on. I've used this product for over 15 years, =
making molds of knotted twine, wheat grasses, impressions of antique sprigg=
ing, and so forth. Rubber a bit more forgiving as regards to undercuts. I d=
ust cured molds (rubber and plaster)with corn starch as a release agent. So=
me molds you can quickly strike against smooth plaster bat to get a release=
and judiciouly lifting of the rubber compound to release clay. Plaster spr=
iggs are wonderful for certain work taken off plasticine originals. Using t=
he rubber and the plaster techniques allow endless possibilities for unique=
molds which can become part of your overall "pot vocabulary". When plaster=
mold has dried completely I sometimes paint some spar varnish on the top a=
nd a bit down the sides to prevent chipping and dings. Note: NOT on the wor=
king part of the mold.

One of my favorite toys was a kit where you melted rubber and poured
it into molds. Wriggly things, soldiers, guns. And then we'd make
crutches, bandages and coffins. The rubber was very hot and I
remember getting burned a lot! Fun to mix different colors. Creepy
Crawlers!
