Sorry folks, my last several posts to this list came back "Undeliverable".
Wouldn't you know the one that got through was MISTAKENLY sent to this
list. Oh well, it's not that this is a group unconcerned about art material
safety. I was researching polymer clays & was able to obtain test data that
really opened my eyes. MSDS sheets alone really do not tell a consumer
enough of what they need to know. Test data reveals the threshold values
established for a particular product. A consumer really needs to see the
test data (tiny fractions in the case of p.c.) & multiply it against their
body weight & frequency of product exposure. It was also interesting to
find out that, according to the Lewis Dictionary of Toxicology, there is no
commonly accepted usage for the term "non-toxic", as toxicity is modified
by many factors (including, of course, the weight of the child).
