Sludge buildup in pots can be tracked quite adequately using the auto-
mation system that records every shot of alumina added to each pot over
a long period of time. Over a period, such as three to six months, the total
amount of alumina fed to any pot can be compared with the metal pro-
duction and the measured shot weight to conrm the difference between
the amount of alumina fed and the amount used to make aluminium
(Faraday’s law applies, dictating that 1.90 to 1.92 kg of alumina is used up
