In chemistry, Muslim scientists carried out perfume distillation, glass making, minting of coins and grouping chemicals based on chemical characteristics, which later on led to the modern periodic tables. In 780, Jabir ibn Hayyan, a Muslim chemist who is considered by many to be the father of chemistry, introduced the experimental scientific method for chemistry, as well as laboratory apparatus such as the alembic, still and retort, and chemical processes such as sublimation, distillation, liquefaction, crystallisation, and filtration. Ibn Hayyan also identified many substances including sulphuric and nitric acids. Al-Jazari developed mechanical devices like watermills and water wheels to ease water management.
