The Sluice is a device that is used to process Ore Deposits, producing the same results that Panning does, with different probabilities.
The sluice is made from sticks and lumber.
When placed, the sluice takes up two blocks. Water must flow through the top of the sluice and out the bottom in order for it to operate. The sluice is able to work when water appears to be flowing through it. The water flowing into the sluice must be the last block of a water stream. There must be an empty block below the bottom of the sluice for water to flow into.
