I haven't noticed any Hammerite flavor in the biscuits yet, but I do leave the door open a while after drying or baking paint. I also fan it open and closed several times after preheating it before it's next use.I believe the actual effects of the fumes is worse than any odd taste in the chicken would be. You definitely want some windows/doors open, or it will overtake you pretty good.

I had to dry some paint last night, and noticed I had told you wrong. On my oven at least, 225 is way too hot. It's actually more like 160 to 180 on the dial, in the "warm" range as marked. Sorry about that, my memory of things I see even every day is not too good. May be the paint fumes........
