Destilação.

Distillatio, by Phillip Galle.


Most of us who have been lucky enough to perform distillations know the thrill of winning a clear “spirit” from a dark and dingy solution, capturing a pure oil from a messy residue and even witnessing the collected distillate’s abrupt solidifi- cation into white crystalline needles. A crude fermentation mixture will, upon distillation, yield an intoxicating “spirit of wine.” Small wonder that a synonym for distillation is “rectification”—making things right. Indeed, distillation itself may almost be regarded as a religious act of ascent and descent:
Ascend with the greatest sagacity from the earth to heaven, and then again descend to the earth, and unite together the powers of things superior and things inferior. Thus you will obtain the glory of the whole world, and obscurity will fly away from you.
