All the dental talk finally jogged a stray question out of me.
Do you have any experience using alginate for molds? As in using
an object for a mold, shooting one wax and cleaning up the model
before making the permanent rubber mold?
Dental alginite being dental is very costly. Try

They sell a couple of different types or at least materials that
are made for the art industry. I went to a workshop in Santa
Barbara last year and one of the slasses was body molding put on
by Mark Prent of Pink House Studios. They have a couple of
alginite materials as well as a body safe silicon rtv. They have
videos on body molding and they should have a price list of
There is also a material called molouage (spelling???) that
turns liquid when heated, and hardens upon cooling. The heat
required is not so hot that it will burn your skin so it could be
useful for quick, short lived (but longer than alginite) mold
material. Douglas asn Sturgess sells it also along with all
sorts of clays, waxes, RTV's, colorants, tools and equipment.
So many folks are so fearful of giving out <> is
propirtary Most mold makers are so tight lipped
they squeek. I have been making rtv molds for jewelry, and
mostly for my foundry for about 7 years now and I am more than
happy to share what I know. I usually learn more than I give
whenever I am showing someone what I like and do not like in a
particular process. I just really find it offensive when I help
a person through years of learning curve, and then have them come
up with what they <> is a really new slant on something
but will not share it with you or anyone else. This happened
years ago when I was organic farming with a new to farming local
grower. Needless to say, I don't bother to share with him
Lastly, if you havn't tried RTV materials, really take a look at
them. You can make a mold of just about anything and I do mean
anything. Surface coatings (hardeners), thickness building
methods (ie wax spray, schellac etc.) and release agents may or
may not be needed, but the choice of materials and propertied
available is amazing. I just cant understand why anyone would
use vulcanized materials except that if they have been using them
for ever and just are not willing to learn something new.
Brother, did I ever get a lot out of THIS 2 cents worth!!
