Desalination -- the removal of salt from water -- is an important process for providing the fresh water we need, but it's quite expensive in terms of energy. In this Practical Engineering video, Grady demonstrates small-scale versions of the two most common methods for purifying water: distillation and reverse osmosis.

Book of the Day – Alchemy: Science of the Cosmos, Science of the Soul
Today’s Book of the Day is Alchemy: Science of the Cosmos, Science of the Soul written by Titus Burckhardt and published in 1997 by Fons Vitae (the book was originally published in 1960, in German, under the title Alchemie, Sinn- und Weltbild).
Eminent Swiss metaphysician and scholar Dr. Titus Burckhardt (1908 – 1984) was an expert and a leading member of the Perennialist or Traditionalist…
Ms. Codex 1671 is an 18th c. French collection of works on distillation, fermentation, and other chemistry-related procedures. It's divided into sections for animal, vegetable, and mineral.
After the whitening of the albedo comes the last phase of the Great Work: the red phase, or reddening.
The white phase consisted of an intense process of purification, in which all the rotting decayed matter that had died during the nigredo was thoroughly cleansed of impurities. What was left was then considered clean but also very sterile, incapable of producing new life and lacking…
24.11.2022 || Dia de destilação no laboratório de Síntese Orgânica. Finalmente consegui destilar o THF !! Agora estamos na etapa de análise no cromatógrafo gasoso e o espectrômetro de massas. Espero que a destilação tenha dado certo.
