− | :The '''catchment area''' is located at the top of the piston. After the piston is dropped, the magma will spread out around the catchment area. In a repeating magma piston, some of the magma is used to cast obsidian on top of the piston, in order to reuse it. The volume and size of the catchment area must be carefully calculated to ensure that you won't have too much or too little magma above the piston for casting. Ideally, you want the depth of the magma above the piston to be 2. If the depth is 1, then the magma might evaporate and you won't be able to repair your piston. If the depth is greater than 2, then you're wasting magma if you cast it into obsidian | + | :The '''catchment area''' is located at the top of the piston.

If you need a catchment area smaller than possible with bridges or floodgates, you may use a floor-less [[Floodgate#Placement|floodgate]] to prevent the magma entering that square, while keeping the piston free to fall. |
