PLEASE, PLEASE, PLEASE
Get a MDSS (Material Data Safety Sheet) on this meterial BEFORE you even
CONSIDER working with it. Also consult the technical literature about it.
Once you understand the hazards, I think you'll forgo the possible red
color, unless you have outstanding technical abilities and have a really
super studio setup (like maybe with an enclosed hood for weighing, and very
sophisticated firing controls ).
BTW, ...............you of course know the federal leaching limits (LAW)
and have a testing lab lined up ???
This stuff makes a couple of teaspoons of Barium Carb. a day seem like
health food.
A substitute might be an encapsulated cadmium based stain, but they are too
new for me to know much, particularly about the health issues and the
leaching effects. Possible that not much has been studied yet.
Karl P......... know anything about cadmium release and encapsulated
stains?
Monona....... you out there? Could use a comment here, I think.
Ron....Tony......any input?
Best,

Goodness yes.
The Health and safety regs in the ceramic and enamel industry in the UK
are horrendous for Cadmium, very regular medical tests, incineration of
workclothes, separate production facilities from normal stuff controlled
waste and water out.
I think the release rates for Cd are set at half that of Lead. (And to
think that 10 years ago people used to gaily use 5% CdS/SeS with bits to
produce reds).
(Winge MODE ON)
One of the problems in big plants these days is that the design
and marketing departments are often out of touch with H&S issues and
with 'downsizing' the technical control people are let go (Fired) as
they don't produce anything except bottlenecks (!!). (Well We've spent
all this money on documenting Quality so why do we need these people)
This puts the onus on suppliers to be careful and get involved in
telling Design why they cannot have Scarlet unless they fancy setting up
a parallel processing shop for 500 units a year. (Why don't we try
autumn browns again? )
(WINGE MODE OFF)
Now the craft potter could probably set up and subcontract doing only
reds and oranges if they had the testing routine established but the
initial outlay would probably be expensive.
It would be simpler to use a reduction copper.
Ah well another project to look at in the next millenium.
