Proposal: Waste Breakdown and Reclamation System... sadly, as I see it, it requires two characters, unless someone found a way to get into both Contractor and Shadowright with one character.
Blueprint: Waste Breakdown and Reclamation System
Principles Necessary: KALD 101, KALD 207, ALCH 364, YGGD 212
Prestige Class: Contractor 2 (Amazing Alkahest), Shadowright 2 (Xanthous Xception)
Explanation: The WBRS (I really need a cooler name for this...) takes an input of any object, and breaks it down (as per Amazing Alkahest), in order to pick out the pure components of the object placed inside of it.
The WRBS requires a container (likely a square prism, but that's simply my preference), with four layers (from top to bottom, 1 through 4):
-The container, first, is made of yellow, orange, blue, and red filters, creating a square prism with dimensions of your choice (but certainly much taller than it is wide or long, and with a maximum height the maximum diameter of your YGGD 212 bubble, and a minimum height of 19'). The width and length are decided by the size of your Phlogiston cube. On one tall face (side), you must leave a small window in Layer 2, and you must leave a small window on Layer 1 (the top face), though having a way to close those windows is a necessity (using a smaller preparation of those four Filters on some sort of hinged apparatus is preferable).
-On the bottom of Layer 4is a cube of Phlogiston (of a maximum size of Medium (from what I can tell, 4'-8' to an edge, I recommend 4' wide by 4' long by 8' tall), and this layer is just as deep as your cube; it needs no spare space around it. It is separated from Layer 3 by yellow, blue, and orange filters, so that only the heat from the Phlogiston may pass through.
-Layer 3 is initially empty. This layer is only a few inches deep, and serves to catch the Alkahest. It is separated from Layer 2 with a yellow filter prepared with Xanthous Xception - Alkahest.
-Layer 2 is also initially empty, though it is 5 feet tall, at a minimum, and 5' taller for each size category above medium your Phlogiston is. It is separated from Layer 1 with a Red filter. You must have a way to seal off Layer 1 from Layer 2 with relation to an Alkahest Solution, which I would use a mobile Blue filter for (you can slide it in and out of the WBRS by attaching it to a rod and having a slit in the tall face with which to move it; as a Wall of Force, it is approximately 1/16" thick.
-Layer 1 is the same size as Layer 2, though it begins filled with a solution of Alkahest in Layer 1 (add the water and Alkahest through the hole in the top face).
To use the WBRS, add your object through the hole in the top face, and close it. When it is done dissolving, remove the blue filter, allowing the solution (which is now Alkahest + your object of choice) to fall into Layer 2. Add the Blue filter once more. The Phlogiston boils off the water from the solution, which returns your object (now in nice, easy-to-handle, dissolved and separated chemical components) to solid state along with the Alkahest. The Alkahest falls into Layer 3, while the water vapor rises back into Layer 1. The water vapor condenses as it cools (isolated from the Phlogiston by the Red Filter), returning to liquid state in Layer 1, and refilling that chamber. Once all of the water has boiled off, feel free to reach into Layer 2 (with your heat protection of choice) to retrieve your object's components, and place them wherever you need them. Next, reach back into Layer 2, then through the Yellow filter into Layer 3, to remove your Alkahest. Return your Alkahest into Layer 1 (with the top opening), allow it to dissolve, and you may begin breaking down more.
At your disposal, you can use the aforementioned YGGD principle to simply reverse gravity and cause the Alkahest to "fall" into the water (make sure the top opening is sealed!), because your Phlogiston is sealed in with the Yellow filters. You just need to return gravity to normal before you run the WBRS again.
