Have often wondered about all those "safe" chemicals. My mom was a professional portrait artist/sculptor, and growing up the house always smelled of Turpentine
& xyline. And she never opened doors or windows, either, said the stuff was perfectly safe (like cigerattes?) In fact I still have a whole box of all her old oil paints and some of the clay she used to use. Couldn't bring myself to throw it out, the stuff was so expensive. I never wondered til now, whether this had a hand in the thyroid disease we both ended up with to say the least! Geesh.
