Distillation and laboratory apparatus
A method for separating liquids by their boiling points, together with the set of glassware for it: the still, the water bath, sublimation, filtration. Alchemy left to science not gold but exactly these tools and procedures, and with them the idea of purifying a substance.
Detailed descriptions of the apparatus survive in Zosimos of Panopolis (about 300 CE), whose tradition grew out of the craft of Egyptian goldsmiths and dyers. Arabic texts of the 9th-10th centuries (the Jabirian corpus, al-Razi) systematised the vessels and the operations and passed them on to the Latin West.
A false goal with a working practice: it is through this glassware that the road to 17th-18th century chemistry runs.
Why this date
Approximate. The earliest surviving description of distillation apparatus (alembic, kerotakis, tribikos) is in the writings of Zosimos of Panopolis, c. 300 CE; Zosimos attributes it to Maria, who by his account lived in the 1st-3rd centuries, but no text of hers survives. The Jabirian corpus, which systematises vessels and operations, is dated to c. 850-950 (Kraus 1942-43) and single authorship is disputed. The previous year 850 reflected the Jabirian corpus rather than the first record; claims of Mesopotamian distillation in the 4th millennium BCE (Levey 1955) are not regarded as proven.
What it grew from
-
Copper smelting from ore
influenced · Confidence: medium
Greco-Egyptian alchemy, where distillation apparatus is first described, grew out of the craft of metalworkers and goldsmiths (recipes for imitating gold and silver in the Leiden and Stockholm papyri); without metalworking this laboratory tradition would have arisen later or differently, but distilling liquids does not physically require smelting.
Dispute: Historians agree that the practical root of alchemy lies in the craft of working metals, but the link runs through goldsmithing and the imitation of metals, not through smelting from ore. No historian has been found who states that smelting was a necessary condition for distillation.

In the cosmopolitan crossroads of Greco-Roman Egypt, the two streams of craft traditions and philosophical traditions coexisted. Their merger - probably in the third century AD - gave rise to the independent discipline of alchemy.

Fermentation as a reproducible practice: beer, bread, wine
influenced · Confidence: medium
Spirits can be got only from an already fermented liquid, so the whole alcoholic branch of distillation rests on fermentation; the distilling vessels of about the third century were still working on other substances, and the distillation of wine in Europe is conventionally dated only to the twelfth century.
Dispute: In the Oxford Companion to Spirits and Cocktails Wondrich sets out the received dating (the distillation of alcohol unknown to Greco-Roman antiquity and reaching Europe only in the twelfth century through Arab mediation), examines its two grounds and finds them unconvincing ("Neither of these objections is conclusive"); the earliest traces of a fortified drink he places in northern India. So the still and the distillation of alcohol are separated by roughly a thousand years, but that dating itself rests on the silence of the sources.

What grew out of it
-
Mass balance and the conservation principle
influenced · Confidence: medium
The laboratory practice of alchemy (analysis and synthesis, weighing of ingredients and products, with an explicit mass-balance principle already in Van Helmont) forms a continuous line to Lavoisier's quantitative chemistry.
Dispute: Distillation is counted from Zosimos (c. 300), whereas the historians on whom this continuity rests speak of Geber (13th c.), Van Helmont (17th c.) and Starkey: what is at issue is the alchemical laboratory tradition as a whole, not Zosimos himself. Newman stresses that mass balance among alchemists coexisted with Aristotelian physics in a "subterranean and uneasy" position.

Van Helmont's weight balance and the willow experiment (Ortus medicinae)
influenced · Confidence: medium
Van Helmont's weight experiments grew out of the alchemical laboratory tradition of cycles of analysis and synthesis, in which mass balance had been implicitly assumed for centuries; without that tradition his method of comparing input and output on the balance would have arisen later or differently.
Dispute: Distillation is counted from Zosimos (c. 300), while Newman writes of the alchemical tradition in general, not of distillation; the willow experiment needs no distillation. The historians confirm the continuity of the tradition but do not name distillation itself.

Mineral acids of the pseudo-Geber corpus
prerequisite for · Confidence: high
The claim rests on the History section of the Wikipedia article. A verbatim quotation is needed from the work it cites: Karpenko V., Norris J. A., «Vitriol in the History of Chemistry», Chemické listy 96, 2002.
The mineral acids of the pseudo-Geber corpus are obtained by distillation: the earliest recipe for nitric acid prescribes distilling a mixture of vitriol, saltpetre and alum, and without distilling apparatus such a product is physically impossible.
Dispute: Distillation is counted from Zosimos (c. 300), whereas distilling acids requires the more advanced vessels and furnaces of the Arabic-Latin tradition of the 9th to 13th centuries (the Jabirian corpus, al-Razi): the continuity runs from distillation as a method in general. Karpenko and Norris give the De inventione veritatis recipe in their own translation, and admit that their remark on a possible distillation of vitriol in the Summa itself is unclear.
