Thanks very much to everyone who gave me suggestions re. my throwing =
problem. I
have found that the clay which was sold to me as a throwing clay was made =
for
casting so that sort of answers everything. I found some instructions on =
making
casts in my books but, no matter how many times i go over them, I am left
wondering how to do it. I will check out the archives and see what I find.
In the meanwhile i have another question. I want to color clay with oxides =
and
am wondering if they pose any health problem as I intend to work them into =
the
clay by hand. Can anyone help me with this?
Thanks,

Don -
As I understand it (from several sources including our own Dr. Edouarde
Bastarache), as long as you have no open sores on your hands, and as long as
you wear a properly fitting good quality dust mask while handling the dry
materials, you are fine. The oxides are too coarse to pose any danger from
dermal absorption.
Good luck -

Hi
i took a class with an instructor who put oxides and stains into the clay
bodies
we wedged literally for hours
each of us - about 8 eight students it took the better part of the 21/2
hr class and a lot of stain the lighter the color the more stain it took
even the red iron oxides took a lot of stain for the 10 lbs i was wedging
not everyone used the latex gloves since there were not enough to go
around that first time but we all were sure that the person working the
chromium oxide had the first choice the results of not weding forever
were at best the wavy moray effect at worst blurry ueven coloring
good luck on the upper body workout (wedging)

There seems to be strong indications that the fumes from Manganese pose a
serious problem during firing - I would make sure you use good kiln room
ventilation. Chrome and Cadmium are also volitile.
The dust from clay in the workshop can be a hazard - depending on how you
clean. If the studios I have seen are any indication it usually is.
Knowing which oxides to look out for should be a prioroity for us all.
