Cornish Boiler (block)
Starts the Cornish Boiler.
Normal single-flue boiler for low steam production.
The crafted block is the firebox end of the machine: stand where the firebox is to be and place it in front of you, and the vessel is raised from the cells beyond it. Ctrl and shift and right-click outlines the cells still missing; a plain right-click with a stage's materials in the hotbar raises the next stage. Its look-at line reports the whole vessel, water, steam, pressure and fire, and breaking it takes the construction down and returns this block with all of the materials.
Interaction
- Right-click to show multiblock structure
- Hold right-click to open or close the lid
- Right-click to pour in water
- Right-click to bail out water
