A method of feeding a pulverulent batch material into a furnace in the manufacture of glass. The pulverulent batch material is fed from a first bulk batch feeder (46) at a first batch feed rate, and from a second trim batch feeder (56) at a second trim batch feed rate. The trim batch feed rate is equal to or less than 10% of the total batch feed rate. The trim batch feed rate is varied in response to the level of the glass melt. The use of trim electrodes and trim burners is also disclosed. |
