bronze
Let an agent explain bronze, relay its composition, types, history and uses from metallurgy and archaeology sources, describe the named types, note lead considerations, and distinguish bronze from brass, pure copper, other alloys and the Bronze Age as a period.
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 bronze, relay its composition, types, history and uses from metallurgy and archaeology sources, describe the named types, note lead considerations, and distinguish bronze from brass, pure copper, other alloys and the Bronze Age as a period.
An alloy of copper, traditionally with tin, and often with other elements such as aluminium, nickel, zinc or lead, harder and more durable than pure copper and easier to cast, used since the Bronze Age for tools, weapons, bells, statues, coins and bearings, with the registry aliases naming specific compositions and types such as bearing bronze and aluminium-bronze; bronze gave its name to a period of prehistory and remains important for sculpture, marine fittings and machinery. Some bronzes contain lead, a health consideration for certain uses, and antique bronzes are conserved as heritage.
What it is for: A durable copper alloy for casting and construction.
It can be explain composition and types; relay history and uses; describe named types; note lead considerations.
Distinguishing features
Copper-tin alloy
Hard and castable
Ancient and modern use
Named the Bronze Age
What it looks like
A hard golden-brown to reddish metal, often cast into tools, statues or fittings.
Physical character
base: copper with tin and other elements note
Bronze Age: a prehistoric period note
registry parents: copper-based alloy, sculpture material note
How it is recognised
Copper alloy, traditionally with tin
Bearing bronze, aluminium-bronze and other named compositions
Brass is copper with zinc; pure copper is softer; other alloys use different metals; the Bronze Age is a historical period
