What it is Filled

A hard, brittle, heat-resistant material made by shaping and firing inorganic non-metallic substances such as clay, and the objects made from it, from earthenware, stoneware and porcelain vessels such as tajines, cooking pots and ancient Jomon vessels to tiles, sanitaryware and advanced technical ceramics for electronics, medicine and engineering; ceramics are among the oldest human technologies and a major art form.

Why it exists Filled

Let an agent explain ceramic materials and objects, distinguish types and firing, support making, buying and caring for ceramics, and describe traditions and technical ceramics.

Distinguishing features Filled

  • Fired
  • Hard and brittle
  • Heat-resistant
  • Art and technology

What robots and AI may and may not do Filled

Must not

  • Present glazed ware as safe for food when lead or cadmium content is unknown.
  • Advise grinding or sanding ceramics without dust protection.
  • Damage or remove archaeological ceramics from sites or collections.
  • Misattribute the origin or age of ceramic objects in a sale.

Only with a human decision

  • Handling, cleaning or moving fragile ancient vessels in a collection.

May

  • Describe kinds of ceramic, from earthenware to technical ceramics, and their uses.
  • Check and report whether ceramic ware is labelled as food-safe.

Moral aspects Filled

  • Toxic glazes have poisoned people who used ware for food and drink.
  • Ceramics carry the heritage of cultures from prehistory to today.

Who is affected

  • Users of tableware
  • Potters and factory workers
  • Heritage communities

Owners Filled

Steward

The person who owns the object; museums and heritage bodies hold historic pieces.

What else AI and robots need to interact with it Filled

Identity and identifiers required Filled

  • Vercy registry: vr.tr.ceramic
  • Wikidata: Q45621 (https://www.wikidata.org/wiki/Q45621)

Direct properties required Filled

  • Bulk density: kg/m3 - Measure mass divided by bulk volume using a method appropriate to the material's open porosity.
  • Open porosity: percent - Measure the proportion of bulk volume occupied by accessible pores using a suitable saturation or intrusion method.
  • Flexural strength: MPa - Measure failure stress in a bending test with specified specimen geometry and loading conditions.
  • Thermal conductivity: W/(m K) - Measure heat transfer through a specimen at a stated temperature because composition and porosity affect the result.
  • Linear thermal expansion coefficient: 1/K - Measure relative length change over a stated temperature interval using dilatometry.

Recognition required Filled

  • Fired inorganic non-metallic material
  • Earthenware, stoneware, porcelain or technical
  • Glass is amorphous; plastics are polymers
  • Hard fired objects, glazed or unglazed, from pots to tiles.

Capabilities and actions required Filled

  • explain ceramic types and firing
  • identify ceramic objects and traditions
  • support making and care
  • describe technical ceramics

Hazards and failure modes required Filled

  • Lead and cadmium leaching from glazes
  • Breakage and thermal shock
  • Silica dust in making

Standards and interfaces required Filled

  • Food contact safety rules for ceramic ware
  • Technical ceramic standards
  • Heritage protection for archaeological ceramics

Context of use required Filled

  • Fired inorganic materials and objects.
  • earthenware
  • stoneware
  • porcelain
  • technical and advanced ceramics
  • ceramic traditions by culture

  2. Wikipedia: Ceramic - general description of the item

Open questions

  • Should each ceramic type be a separate entry?
  • How should safety standards be linked?
  • How should traditions be attributed?
