The steam partial pressure of the internal environment within a bright annealing furnace generating a boron oxide is reduced to less than about 1x10<SUP>-5 </SUP>by lowering the dew point of the internal furnace environment. The dew point of the heating environment within the bright annealing furnace is lowered by introducing a gas having a hydrocarbon component or a chemical compound having a carbon component into the furnace.
