Experience using Reduc-it


#1

Anyone have any experience with a material called Reduc-it or
anything similar? Rio Grande sells it, and the description says it
does a 50% reduction of a master. I have a couple masters that I need
to reduce to a couple different sizes of the same design, and was
wondering what experience (Good and Bad) that anyone may have had
with it or other products like it. Also, I am curious about with it
is if it possible to reduce it more or less using an additive with
it, and how is the detail on it when you do reduce it?

Thanks,
Vince Woodard

I’ve used Reduc-it and it’s pretty worthless for jewelry, you’ll
lose fine detail and it leaves a rough finish. You basically end up
with a slightly smaller, plaster part.

For larger pieces like small sculpture, it might be useable if you
were willing to rework it after shrinking.

I have used irt a few times to make smaller molds of abjects or
textures for use with PMC, rather than casting. It is quite easy to
use. When it first sets, it has a gelatinous texture and is quite
fragile, but as it cures, it shrinks and the surface becomes firm
but much less smooth. My main complaint about it is the final
surface-- not the smooth, polished one I began with, producing metal
that needs smoothing and polishing.

The caveat here is that I was making reduced molds, not reduced
models, so that may make a difference, I suppose. I think it had a
tendency to curl if not turned occasdionally, but I don’t remember
for sure.

I’m not aware of a way to adjust the amount of shrinkage.
