The Alchemical Furnace is a block added by Thaumcraft 4. It works in conjunction with Arcane Alembics to create essentia.
The Alchemical Furnace is powered by solid fuels such as Coal or Alumentum. It will consume items offered and convert them into its aspects stored in Arcane Alembics above it. Only five may be stacked on top of the furnace; because of this, items that contain 6 aspects will not start up the furnace and remain unburned. The essentia can then draw directly from the alembic into Glass Phials or into Warded Jars via Essentia Tubes. The Alchemical Furnace can only store 50 units of unprocessed essentia; this is depicted by the purple bar on the left side of its GUI. If it is full the furnace will stall and the current piece of fuel will be used up. Any item composed of more than 50 essentia points will not be burned either even if it has at most five aspects.
In the future you will definitely need to have ready access to multiple different kinds of aspects - not just primal aspects drawn from your wand.
Using basic alchemical principles you have devised a way to break down objects and convert them into essentia.
The first step in this process requires an Alchemical Furnace. The alchemical furnace works much like a normal furnace by burning coal to produce heat, but instead of smelting ore into metal, it breaks down objects into a slurry of raw, unprocessed essentia.
The next step in the process is to take the essentia slurry and distill it using an Arcane Alembic.
To work, arcane alembics need to be placed on top of an alchemical furnace. The essentia slurry will slowly be drawn into the alembic and the individual aspected essentia separated out.
If the alchemical furnace is being powered by alumentum, this distillation process is much faster.
You can stack up to 5 different alembics on top of a single furnace.
The essentia can then be extracted out of an alembic using phials.
