I am fairly new to poly clay - I've spent the last few days making molds, then using the molds. So I've spent a fair amount of time firing these pieces in the oven, with what I thought was enough ventilation. While I feel I followed the directions properly as none of my pieces were burned or scorched, and they are all nice and solid, I ended up in respiratory distress after a few batches. My upper respiratory tract is still a bit irritated but was extremely irritated the first night and I nearly went in for treatment, but felt they probably wouldn't be able to help because it wasn't bad enough. I am wondering if anyone else has experienced this. I've looked online and found several places that talk about the hazards of the fumes if these clays are overbaked because of the release of hydrochloric acid gas. There seems to be much debate over this issue in getting better warnings onto the packages. I used an entire package of Sculpey over the past two days and nowhere on that box is there mention of hazardous fumes if this product is overbaked. There is only one little sentence: DO NOT OVERBAKE. No reason behind that statement is given. I have asthma issues sometimes - usually during allergy season or around certain animals so I do have a somewhat sensitive system. But having said that, there should still have been some kind of indication on the box. I could be argued that this respiratory issue is completely unrelated to the Sculpey product, but, the first time I used it about two years ago resulted in a similar issue. That was with Fimo. I have found several sites that talk about the harmful effects of breathing in the fumes from poly clays and the symptoms are exactly what I'm experiencing. I'm wondering what thoughts some of you have on this topic and if anyone else has experienced a problem with poly clay. Also, what suggestions would anyone have, other than to stop using it. Does anyone know if you can make good molds out of the air-dry clay? Is it as long-lasting as the kind you have to bake? What is the lifespan of air-bake vs. baked clay? I appreciate any help or suggestions.
