Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago.

Learning by listening is a great way to:
- increases imagination and understanding
- improves your listening skills
- improves your own spoken accent
- learn while on the move
- reduce eye strain

Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.

SUMMARY
=======
Alchemical studies produced a number of substances, which were later classified as particular chemical compounds or mixtures of compounds.
Many of these terms were in common use into the 20th century.

Aqua Fortis – nitric acid, formed by 2 parts saltpetre in 1 part (pure) oil of vitriol (sulfuric acid). (Historically, this process could not have been used, as 98% oil of vitriol was not available.)
Aqua Ragia/Spirit of turpentine/Oil of turpentine/Gum turpentine – turpentine, formed by the distillation of pine tree resin
Aqua Regia (Latin: "royal water") – a mixture of aqua fortis and spirit of salt
Aqua Tofani – arsenic trioxide, As2O3 (extremely poisonous)
Aqua vitae/Spirit of Wine – ethanol, formed by distilling wine
Aurum - gold
Azoth - initially this referred to a supposed universal solvent but later became another name for Mercury
Bismuth (German: Wismuth)
Bitumen - highly viscous liquid or semi-solid form of petroleum
Blende
Blue Vitriol/Bluestone – A mineral; copper(II) sulfate pentahydrate.
Brimstone – sulfurFlowers of sulfur – formed by distilling sulfur.Butter (or oil) of antimony – antimony trichloride. Formed by distilling roasted stibnite with corrosive sublimate, or dissolving stibnite in hot concentrated hydrochloric acid and distilling. SbCl3
Cadmia/Tuttia/Tutty – probably zinc carbonate
Calamine – zinc carbonate
Calomel/Horn Quicksilver/horn mercury – mercury(I) chloride, a very poisonous purgative formed by subliming a mixture of mercuric chloride and metallic mercury, triturated in a mortar and heated in an iron pot. The crust formed on the lid was ground to powder and boiled with water to remove the calomel.
Caustic potash/Caustic Wood Alkali – potassium hydroxide, formed by adding lime to potash
Caustic Soda/Caustic Marine Alkali – sodium hydroxide, NaOH, formed by adding lime to natron
Caustic Volatile Alkali – ammonium hydroxide
Chalk – a rock composed of porous biogenic calcium carbonate, CaCO3
Chrome green – chromic oxide and cobalt oxide
Chrome orange – chrome yellow and chrome red
Chrome red – basic lead chromate – PbCrO4+PbO
Chrome yellow/Paris Yellow/Leipzig Yellow – lead chromate, PbCrO4
Cinnabar/Vermilion – refers to several substances, among them: mercury(II) sulfide (HgS), or native vermilion (the common ore of mercury).
Copper Glance – copper(I) sulfide ore.
Corrosive sublimate – mercuric chloride, formed by subliming mercury, calcined green vitriol, common salt, and nitre
Cuprite – copper(I) oxide ore
Dutch White – a pigment, formed from one part of white lead to three of barium sulfate, BaSO4
Flowers of antimony – antimony trioxide, formed by roasting stibnite at high temperature and condensing the white fumes that form. SbO3
Fool's gold – a mineral, iron disulfide or pyrite; can form oil of vitriol on contact with water and air.
Fulminating silver – silver nitride, formed by dissolving silver(I) oxide in ammonia. Very explosive when dry.
Fulminating gold – gold hydrazide, formed by adding ammonia to the auric hydroxide. When dry, can explode on concussion.
Fulminating gold – unstable gold carbonate formed by precipitation by potash from gold dissolved in aqua regia
Galena – lead(II) sulfide. Lead ore.
Glass of antimony – impure antimony tetroxide, SbO4 formed by roasting stibnite. A yellow pigment for glass and porcelain.
Glauber's Salt – sodium sulfate. Na2SO4
Green Vitriol – a mineral; iron(II) sulfate heptahydrate. (or ferrous sulfate)Marcasite – a mineral; iron disulfide. In moist air it turns into green vitriol, FeSO4.
Rouge/Crocus/Colcothar – ferric oxide, formed by burning green vitriol in airGum Arabic – gum from the acacia tree
Gypsum �� ...
