Hi there: Mould soap should be availabl from our ceramic supply houses. The
green soap-correctly named ' Tincture of Green Soap' is available from a
pharmacy. Usually the independent pharmacies will have it or will be happy to
order it for you.

Hello List members;
Another question.
I want to make some plaster moulds over a roasting pan for drying clay. I
have it covered with plastic at present but am reading I need to use mould
soap or green soap on it before poring the plaster . I don't know exactly
what this is and can I use something more readily obtainable? Also is it
necessary to treat the inside or outside of the completed mould with
something before using it? One book said to varnish it but wouldn't this
prevent it absorbing moisture when I want the clay to dry out?
Advice, please.
Thanks in advance.

Maridelm what you are looking for is correctly called "Tincture of Green
Soap". Get it at the drug store. Make a mix of half water and half
tincture of green soap and you are ready to go. Apply with a natural
bristle brush. Use a cheap throw-away type from HQ, of Home Depot, or
one of those paint stores. Cheapo is fine, just be sure they are pure
bristle(actually they are hog bristle -- sometimes called china bristle
in the fine arts supply stores.....lets um charge more.
You need twor three, because after you apply the soap and let it dry a
bit, you need to brush it down and smooth it out with a dry brush.
Good luck!!

Maridel, we use a substance called soft soap. As far as we
can make out it is made from a laundry soap and grease.
We dilute it with some water and apply it with a sponge to
the object we want to make a mould of. We make sure that
there is no bubbles to spoil the detail, but you do not need
to do that. We bought it from a firm that wholesaled
cleaning materials to firms, factories. We bought a 25Kg
bucket because we were selling it to other potters. Hope
this helps Ralph in PE SA
