how does the thermostat control the gas valve when tempreture overshot?
the reason i asked for the upper gas burner(element)is bcos some baking need
upper tempreture more than lower temppreture,in electric oven you can have
seperated upper or lower element,but in gas oven case,how can we get it?
I was told that industrial/commercial gas oven does have upper and lower
burner element,is that right?cos i haven't seen one like that before.
i feel that gas oven tends to generate more moisture(gas?)than electric
type(tends to be dry type)and resulting of different
quality for the baked product.
is the any book or web site i can learn more about gas oven?
thanks
