O Learned Ones,
I sculpted a head of plasticine and then made a mold from it. =
Plasticine, of course, has an oil/wax base and it left quite a bit of =
residue which I think will interfere with casting. Is there some kind =
of oil-less soap I can use to gently clean it? What should I use?
(And no, I won't do that again. Duh.)

Dish soap is about the best for this, I think,
though I've never personally tried to slip-
cast past plasticine residue. By the way,
there's no reason you can't still make the
'pattern' for your molds of plasticine. Just
coat them well with spray shellac, then wipe
with mold soap and proceed with the plaster
as usual. (Dish soap works OK as mold soap,
too.) I have made a number of molds this way.

Specifically, Dawn, diluted 3 parts water, 1 part Dawn, brush on three coats, allow
to dry between coats.
Works for me.

Hi All,
I must confess to not reading as many of my clayart emails as I usually do
since I've returned to school. busy busy with wonderful reading and paper
writing and the usual house and kids.
Anyhow, when I saw "Mold question" I didn't think plaster molds, I thought
the mold on my shelves. Is it possible to get rid of this? My basement
isn't very damp and the kiln is even down there. (vented out the chimney as
advised by many clayarters last year...) The moldiest shelf is the one that
holds pots waiting to be fired. what do you all do for your moldy mold
problems?
Also, speaking of the kiln vent, once I had a very full firing and the piece
nearest the intake holes in the lid cracked. has any one else had this
happen? My other Kiln vent question is hold time. I've been giving a hold
time as the first few firings looked like they were cooling to quickly. In
peoples experience is it better to program the hold time or to shut off the
vent at some point in the firing. Is safe to shut off the vent at any point
with a basement kiln?

Mold can cause respiratory problems in people.
Removal of uncleanable surfaces and bleach [chlorox] cleaning is the norm,
use the suggested proportion on the label, not full strength ,and a good
protective gloves and ventilate area well and vacate the area for a time ,
until the fumes are gone after cleaning.I don't know if a mask is made for
this task but you might want to check on that too.
Whether this is a ''permanent '' solution could be an issue, depending on
whether the environment has ventilation and fresh air and sunlight [lol].
In some cases, an additive can be added to paint supposedly to inhibit mold,
but, having used them numerous times I can attest that they have been
ineffectual in a humid dusty environment.The ventilation aspect has a double
edge sword in a clay atmosphere as it,the dust, may well contribute to dust
inhalation intake which can also harm the lungs and respiratory system.

Linda,
If your holes in the top are in the middle of the lid, plug them and move
the holes toward the outside edge of the lid just inside the wall area.
This should stop the cracking and the cold spots on your top pieces.
I leave my vent on during my hold time and do not have a problem.
Best regards,
Tim Frederich

Tim,
I will try this. My holes are not in the middle, but they are in far enough
from the side that they are well over shelf area.
Thank you for your suggestions here and the others that were sent. It never
occurred to me that I didn't have to have as many air intake holes or have
them placed exactly where the template said to put them!
