Feeding. The next process is the feeding process, and in this stage, the glassblowers will be feed. The feeding of the glass gob should be done at an optimum temperature. The temperature is chosen based on the weight and shape of the bottle. Then the glass is fed into the glass-bottle forming machine through the feeder.


Although pure (feed-grade) calcium carbonate is relatively inexpensive, there is another source of calcium that is even cheaper. That is limestone, which costs as little as EUR30 to EUR50 per metric ton. One would be excused to believe that such difference in price is not enough to bother, in the grand scheme of feed formulation.
