Yes Lexxy,=20
plaster can and will absorb moisture very quickly especially if the =
plaster is dry to begin with. Take a moist disk of clay and lay it on =
the plaster, come back in 15 minutes and feel the difference between the =
two sides of the clay.=20
Much of the poured ceramic molds allow you to pour and release in a =
short period of time. So I wouldn't leave anything thrown on the =
plaster, especially plates. The best thing that I can recommend is to =
place your ware on several sheets of newspaper and cover loosely with =
plastic to dry. Avoid drafts that could unevenly dry your work. When I =
am throwing series of pieces, I place them directly from the wheel on to =
ware boards covered with folded sheets of newspaper, move the full board =
to an area protected from drafts and direct sunlight. When a little of =
the moisture is gone, cover with plastic. Check the drying from time to =
time. Change the newspaper often if your pieces are thick.=20
When you have attached spouts, handles, feet to a body of a pot, cover =
the whole piece completely overnight to several days to allow the ware =
to "equalize" in moisture, then dry under loose plastic for a few more =
days. Why take chances, I always loose.
