brick
Let an agent explain bricks as a building material, identify kinds by material, manufacture and period, relay standards, properties and history, and distinguish bricks from blocks, tiles and stone.
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 bricks as a building material, identify kinds by material, manufacture and period, relay standards, properties and history, and distinguish bricks from blocks, tiles and stone.
A rectangular block of fired or sun-dried clay, calcium silicate or concrete used as a building unit laid in mortar to form walls, arches and pavements, made in standard sizes that vary by country and period, from thin Roman bricks to modern perforated blocks; bricks have been made for thousands of years, are stamped by makers in some traditions, and remain one of the most widely used building materials.
What it is for: Building walls and structures in masonry.
It can be identify kinds and standards; explain manufacture and properties; relay history and regional traditions; distinguish from related units.

What it looks like
A rectangular block, usually red to brown from fired clay, with or without holes or a frog, laid in courses with mortar.
Physical character
common metric size: 215 by 102.5 by 65 mm - UK
compressive strength: about 10-100 MPa - by type
How it is recognised

- How should standards be linked by region?
- The registry entry has merged aliases naming types, a historical brick and stamps; should they be split off?
