Its main purpose is to take reduced metal chunks (created in a Slag Furnace) and Sulfuric Acid* to create crystalline metals, which can be smelted into regular metal ingots. *In this newest version Sulfuric Acid is replaced by Aqua Regia.
There are six slots available in the Crystallizer to place items. To process metal chunks, put sulfuric acid in one slot, and spread out your chunks among the remaining 5 slots. Each cycle takes about 20 minutes and will process one item from each slot. The overall amount of metal is boosted about 150% on average during the crystallization process, so if you have filled 5 slots with metal chunks, you typically get 7-8 crystalline metal per 20 minute cycle. The sulfuric acid does not get used.

- Milk + Lime Dye >> Slimeball (milk does not get used up)
Although it can process 5 reduced metal chunks at a time, pipes will not distribute items among the slots, but will move to the second slot only if an item can't fit in the first slot. This can cause a crystallizer to get clogged by having multiple types of metal sent to it, since it only has one output slot.
It also means that an entire stack of chunks can end up in the first slot, which will take 21 hours and 20 minutes to process if powered continuously, with no items in any other slots. Distributing the items manually can speed up the process by a factor of (roughly) 5 in such cases.
