Stovers,

Galvanized metal in stoves gets mentioned occasionally.  Do we have a 
clear answer about what is the temperature at which the zinc makes 
poisonous gases (such as when welding) versus making zinc oxide (the 
white stuff that you can by in a tube to put on your nose to prevent 
sunburn)?   Is it bad if the temperature is at 400 C to 700 C?   Or does 
it need to get much higher?
