Chemistry II

 Some of the breakthroughs in chemistry under the Abbasids:

1.                   Distillation equipment (such as alembic apparatus, stills and retorts) allowed for alcohol (ethanol) to be distilled for the first time (which was used for perfume and sterilization, rather than drinking). Rosewater was also made through distillation.

2.                   Kerosene was was distilled from petroleum by al-Razi in ninth century Baghdad. He described the process in Kitab al-Asrar, The Book of Secrets. Kerosene was used in lamps. Other petrol products were known and used. The streets of Baghdad were paved with tar in the eighth century. And Arab scientists first distilled crude oil to create what we know as petrol.

3.                   Other processes developed and refined, included crystallization, filtration, and steam distillation.

4.                   Strong acids were created for the first time, including nitric, hydrochloric, and sulphuric acid (the ancients had only had vinegar).

5.                   Other elements were discovered, such as arsenic and antimony, and chemical elements were clearly divided into categories and studied.

6.                   Soap was manufactured for the first time; and even glue was made from cheese… a secret recipe described in ibn Hayyan’s (Gerber) The Book of the Hidden Pearl.

7.                   Cosmetics were also developed, including those by the fabulous-sounding ‘Ziryab’ ‘The Blackbird’, a former Persian slave, who is credited with inventing toothpaste. The idea caught on like wildfire. He went on to open a beauty parlour in Andaucian Spain and supposedly pioneered underarm deodorants and the chemical removal of unwanted body hair for women.

8.                   Other inventions were far less whimsical and were snapped up by the military… including potassium nitrate (saltpetre) which enabled a complete recipe for gunpowder (tenth century). Gunpowder had been made and discussed for a long time, but the first book dedicated to it was written in the thirteenth century by Hasan al-Rammah, entitled The Book of Military Horsemanship and Ingenious War Devices.

Chemistry

Modern chemistry may owe more to Islamic science than just about any other area. Its very name of course is derived from al-kemia, the word for alchemy.

Although alchemy was very important, and had come to the Arabs from both India and the Roman Empire, we now understand increasingly how many Arab scientists refuted the belief in transmuting base metals into gold.

Arab breakthroughs in chemistry are plentiful, and were aided by new scientific practice, as we have seen. Tomorrow we’ll look at some of the various that were championed under the Abbasids.

Translations

A huge number of Classical texts no longer exist in their original Greek or Latin, and were brought to the Renaissance through the Arabic. The Abbasids drew from Greek and Roman classics, as well as the classical Persian, Turkic and Indian sources. In this way, information on subjects such as Zero, came to the Arabs (from the Indian subcontinent). Such breakthroughs led to a snowballing effect, with problems of mathematics, physics and so on that were uncrackable before, being solved for the first time.

The House of Wisdom was at first essentially a translation house and giant library. Then gradually it turned into a think-tank, which built on the foundations of earlier cultures, and welcomed Christians and Jews as well as Muslims to study.
