Crucible (Thaumcraft 4)

The Crucible is a block added by Thaumcraft 4, used to create various items.



Creation
The Crucible is created by right-clicking a Cauldron with a Wand (no Vis is used).

Usage
The Crucible is filled by right-clicking it with a Water Bucket, or using a form of pipes.

The Crucible must be "powered" with a heat source directly underneath the block; either Fire, Lava or Nitor.

When the Crucible is filled, after a couple seconds, it will begin to boil- small bubble particles will appear from the surface of the water (those particles may be different colors if Essentia is in the Crucible). If the Crucible is not boiling, it cannot be used to create anything.

Two things are needed in order to create anything: Essentia and a Catalyst.

Essentia is collected by throwing items into the Crucible, after which they are broken down into their Essentia components (for example, a Torch would give 1x Lux).

Once the Crucible is filled with the Essentia a recipe requires, a Catalyst is used to complete the recipe by throwing it into the Crucible. Doing so will use up the Essentia needed for the respective recipe and the completed item will be able to be picked up as a result. Any remaining Essentia is left in the Crucible.

Essentia in the crucible is constantly degrading; Compound Essentia will deform into its component aspects and Primal Aspects evaporate over time. This can cause adverse effects.

Similarly, the Crucible can be emptied with a right-click of the wand, all the Essentia will be dumped into the atmosphere which cases such adverse effects such as, going from bad to worst; Flux Goo Spillage, Flux Gas and Tainted Slime spawning. Effects vary based on the amount of Essentia wasted.

While wearing the Goggles of Revealing or similar, player can view the exact contents of a Crucible by looking at it.
