The crucible is a vital part of Thaumcraft. It is what allows you to do Thaumaturgy. This is accomplished by combining Aspects to form new objects. To create a crucible,  right-click a cauldron with a wand. To start up a crucible, place fire or lava under the crucible, and put water in it, it will then boil.
