What it is Filled
An alloy of copper and tin, sometimes with additional 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; named types such as bearing bronze fall within this sense when they contain copper and tin, while copper alloys without tin, including aluminium-bronze compositions without tin, fall outside it. 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.
Why it exists Filled
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.
Distinguishing features Filled
- Copper-tin alloy
- Hard and castable
- Ancient and modern use
- Named the Bronze Age
What robots and AI may and may not do Filled
Must not
- Cut, melt or clean historic bronzes without a conservator's decision.
- Expose people to lead from leaded bronze through grinding or casting without protection.
- Help trade in bronze antiquities of unclear or looted provenance.
- Misstate an alloy's composition when it is used in food, water or safety parts.
Only with a human decision
- Treating bronze disease or restoring a valued bronze object.
- Melting down or scrapping bronze that may have heritage value.
May
- Identify bronze objects and describe their composition and history.
- Advise on care and conservation of bronze following conservators' guidance.
- Distinguish bronze from brass and from copper.
Moral aspects Filled
- Bronze artefacts hold the history of many cultures and are targets of looting and theft.
- Theft of bronze statues and plaques for scrap destroys public heritage.
Who is affected
- Communities whose heritage is in bronze
- Foundry workers
- Museums and owners
Owners Filled
Steward
The person or institution that holds a bronze object.

What else AI and robots need to interact with it Filled
Identity and identifiers required Filled
- Vercy registry: vr.tr.bronze
- Wikidata: Q34095 (https://www.wikidata.org/wiki/Q34095)
Direct properties required Filled
- base: copper with tin and other elements note
- Bronze Age: a prehistoric period note
- registry parents: copper-based alloy, sculpture material note
Recognition required Filled
- Bronze in this sense is an alloy of copper and tin.
- Bearing bronze and other named compositions fall within this sense only when they contain copper and tin.
- Aluminium-bronze compositions without tin fall outside this sense.
- Brass is copper with zinc, pure copper is softer, other alloys use different metals, and the Bronze Age is a historical period.
- A hard golden-brown to reddish metal, often cast into tools, statues or fittings.
Capabilities and actions required Filled
- explain composition and types
- relay history and uses
- describe named types
- note lead considerations
Hazards and failure modes required Filled
- Lead exposure from leaded bronzes
- Confusing bronze and brass
- Corrosion in some environments
Standards and interfaces required Filled
- Alloy composition standards
- Restrictions on lead in some uses
- Heritage conservation for antique bronzes
Context of use required Filled
- A durable copper alloy for casting and construction.
- tin bronze
- aluminium bronze
- bearing bronze
- bell and statuary bronze
