Control of fire
A controlled process that changes matter: heat, light, protection from predators, later cooking. The earliest secure evidence of burning in an archaeological layer comes from Wonderwerk Cave (South Africa) and dates to roughly 1 million years ago. Fire becomes a regular part of technology only 400-300 thousand years ago, and the ability to make fire rather than merely keep it is attested later still. The dating is disputed by an order of magnitude.
Without control of fire there is no firing of clay, no smelting and no glass.
Why this date
Disputed, spread of an order of magnitude. 1.5 Ma: Koobi Fora and Chesowanja (Kenya), burnt material present, hominin involvement not demonstrated. 1.0 Ma: Wonderwerk Cave (South Africa), which its authors call the earliest secure evidence for burning in an archaeological context (Berna et al. 2012). 790 ka: Gesher Benot Ya'aqov (Israel), clusters of burnt flint. Habitual use of fire in Europe only from 400-300 ka (Roebroeks, Villa 2011). The year follows Wonderwerk as the earliest evidence with microstratigraphic control; older layers of the same cave were claimed in 2026 and are not yet vetted.
What grew out of it
-
Firing of clay
prerequisite for · Confidence: high
Firing clay is physically impossible without a maintained fire: the earliest ceramic figurines of Dolni Vestonice were sintered at 500-800 C, that is, at hearth temperatures.

A firing temperature range of 500° to 800°C was measured and compared with those of hearths and kilns.

Eventually, fire became embedded in human behaviour, so that it is involved in almost all advanced technologies.

Copper smelting from ore
prerequisite for · Confidence: high
Reducing copper from ore requires temperatures from 700 C upward and a reducing atmosphere, which only controlled incomplete combustion of fuel with limited air access provides.

Transparent blown glass
prerequisite for · Confidence: medium
Glass is obtained only by fusing sand with soda and lime at high temperature in a furnace, so without controlled fire there is no glass.

Glass is formed when sand (silica), soda (alkali), and lime are fused at high temperatures.
- Corning Museum of Glass, «Origins of Glassmaking»
the first glass created by humans can be dated to about 4,000 years ago, when craftsmen working in Mesopotamia, the land between the Tigris and Euphrates Rivers, discovered the art of mixing sand, soda, and lime to make glass.

burning took place in the cave during the early Acheulean occupation, approximately 1.0 Ma. To the best of our knowledge, this is the earliest secure evidence for burning in an archaeological context.

The timing of the human control of fire is a hotly debated issue, with claims for regular fire use by early hominins in Africa at ∼1.6 million y ago. These claims are not uncontested ... It was only much later, from ∼300,000 to 400,000 y ago onward, that fire became a significant part of the hominin technological repertoire.

The presence of burned seeds, wood, and flint at the Acheulian site of Gesher Benot Ya'aqov in Israel is suggestive of the control of fire by humans nearly 790,000 years ago.

Direct evidence of early fire in archaeology remains rare, but from 1.5 Ma onward surprising numbers of sites preserve some evidence of burnt material. By the Middle Pleistocene, recognizable hearths demonstrate a social and economic focus on many sites.
