Crucible (Thaumcraft 4)

''"The crucible is an important tool for any thaumaturge. It allows him to render physical objects into their component Essentia and recombine it again as he wishes." - Azanor''

The crucible is the vessel in which all alchemical recipes take place. It is created by placing down a vanilla Cauldron in the world and right-clicking it with any type of wand. No vis is required to do this. Similar to a Cauldron it can be filled with water either by right-clicking with a filled bucket or pipes, however pipes will only "fill" the crucible when boiled.

The crucible must be heated with a source directly underneath the block, such acceptable sources include but are not limited to:
 * Fire
 * Lava
 * Nitor

Once water has sat in a heated crucible for long enough, it will start to boil, which is shown by bubble particle effects that rise and pop from the surface of the water. This is when the Thaumaturge can prepare Alchemical recipes.

Two things are needed in order to perform alchemy. Essentia and a Catalyst.

Essentia is collected by throwing items into a 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. Remaining Essentia is left in the crucible.

Essentia in the crucible is constantly degrading; Compound Essentia will deform into it's 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.

Usage
Right clicking upon the Crucible with a bucket of water will fill the crucible with water. A heat source underneath the crucible such as fire will bring the filled crucible to a boil eventually.

Nitor can be used as a harmless heat source for a Crucible by using it in place of Fire or Lava.

If Netherrack is hard to come by, player can use a Flint and Steel to light a block of any type underneath the Crucible which will bring it to a boil before the fire dies out, making a good way to quickly get Nitor to use for a safe heat source.

Boiling Crucibles will never cool even if no heat source is given.

Bubble Particles will change colour depending on the Essentia the crucible holds.

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

Throwing a catalyst will complete the respective recipe it belongs to, for example Glowstone is the catalyst for Nitor.

Right clicking the Crucible with a Wand will empty it's contents. Wasted Essentia will cause adverse effects depending on how much is wasted.
