The Magma Crucible is a machine which uses MJ power (Minecraft Joules) to melt things into liquid. Typically uses quite a bit of energy. It mainly serves to make lava a renewable resource. It uses 30 MJ/t, so 8 Magmatic Engines are enough to power it with some left over. If netherrack is used it can output enough lava to power the engines and a Thermal Generator.
|Input||Output||Quantity (mB)||Cost (Redstone Flux)||Time (Ticks)||Time (Seconds)|
|Redstone Block||Molten Redstone||900||108000||360||18|
|Ender Pearl||Molten Ender||250||24000||80||4|
|Glowstone Dust||Energized Glowstone||250||20000||?||?|
Notes: before TE v2.0.7 (FTB BETA A pack uses 2.0.5) the Redstone recipe was 1000 MJ for 50mB; with that version is was changed to 1500 MJ per 50 mB; the recipe shown is from v2.1.5 onwards. Molten Ender was added in TE v2.2.0.
- The left side of the interface indicates power storage.
- It is unclear what the lower slot is for.
- The center-left slot is for the input item for cooking. Traditionally placing a bucket in this slot would also extract a bucketful of liquid, but this no longer is the case.
- The center-right shows the cooking progress on the current item. This process is faster when more energy is provided to the crucible.
- The right side shows output storage. Up to 10,000 milliBuckets (10 buckets) can be stored in the crucible itself before it needs to be emptied to make room for more.
The faces of the crucible can be configured from inside the interface by clicking the gear icon to the right labeled Configuration. There are five configurable faces; the bottom-right face is for the rear of the machine. Clicking on one of these faces will toggle its input/output state:
- Orange is an output face (lava or molten redstone). Output can be transported in liquid pipes. This does not require a wooden pipe or a pump to extract the liquid; you may use a golden waterproof pipe directly.
- Blue is an item input face for the item that you wish to cook (e.g. Netherrack)
- Black (or no colored outline) inputs items into the slot under the energy indicator. Again, purpose unknown.
- Off (when the black square is not visible, showing only the face) toggles the face off. It can still receive MJ energy through this face.
Note that toggling any of these faces will also highlight the respective section of the interface in that color.
If one has enough netherrack, or a steady enough supply of it, and seeks only to produce lava without running a surplus of MJ, 2 magma crucibles and 15 magmatic engines will produce no more MJ than what it takes to produce lava, and will produce lava at a rate of about 2 buckets per minute. Less engines will slow the production of lava, while more engines will produce excess MJ. These two magma crucibles will burn 1 netherrack every 10 seconds, or 360 netherrack per hour.
This rate of lava production can feed 7 more magmatic engines with a tiny surplus of lava (or more engines, if they do not run continuously and can pull from a tank of lava that builds up while idle).
If enough resources allow this to be scaled up, keep the ratio of 2:15 to maintain efficiency.
