reduction
Let an agent explain reduction as a chemical concept, relay its role in redox reactions, metallurgy and synthesis from chemistry references, describe industrial processes such as smelting and direct reduction, and distinguish chemical reduction from other senses of the word.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain reduction as a chemical concept, relay its role in redox reactions, metallurgy and synthesis from chemistry references, describe industrial processes such as smelting and direct reduction, and distinguish chemical reduction from other senses of the word.
A chemical process in which a species gains electrons or decreases its oxidation state, the half-reaction paired with oxidation in redox chemistry, including one-electron reductions, reduction of metal ores in smelting of iron, zinc and lead, direct reduction of iron ore by gases in processes such as Midrex, and reductions in organic synthesis with hydrogen or hydride reagents; reduction is fundamental to metallurgy, energy storage, respiration and photosynthesis.
What it is for: Gaining electrons and extracting metals.
It can be explain the concept and half-reaction; relay metallurgical processes; describe synthetic reductions; distinguish other senses.
Distinguishing features
Electron gain
Paired with oxidation
Basis of metal extraction
Many reagents and processes
What it looks like
Not a visible object; reaction equations and industrial furnaces.
How it is recognised
Gain of electrons in a redox reaction
Smelting, direct reduction, hydrogenation, one-electron reduction
Oxidation is the paired loss of electrons; reduction in mathematics or cooking is unrelated

- The registry entry has merged aliases naming processes and a brand; should they be split off?
