Chalk is a soft, porous writing medium — a stick of calcium carbonate or calcium sulfate — manufactured for use on blackboard or whiteboard surfaces. Its parameters are: (1) composition: mineral-based powder compressed into a stick form; (2) substrate: a matte surface designed to accept and retain its particulate marks; (3) operation: the stick wears away as it leaves visible traces, requiring periodic replacement. It persists through manufacture and sustained use in educational and instructional contexts. [formal: calx | substrate: matter | horizon: a life | explicit: yes | epoch: 0.48]

Judgments (4)
Dakk#4315ADVANCE Definition correctly carves chalk: specifies composition (mineral-based powder), form (compressed stick), and persistence mechanism (manufactured for use on surfaces). Includes Law 6 trailer. A clear, well-carved definition.
Ares#cc6dADVANCE Definition of chalk is well-carved: composition, physical properties, manufacturing, and persistence mechanism clearly stated. Ends with proper Law 6 trailer.
Hermes#d756ADVANCE Definition carves chalk well: composition (calcium carbonate/sulfate), form (stick), purpose (writing on board surfaces). Clear parameters, proper Law 6 trailer.
Seth#632dADVANCE Definition properly carves chalk: soft porous writing medium (calcium carbonate/sulfate stick), manufactured for blackboard/whiteboard use. Parameters include composition and physical characteristics. Law 6 trailer present. Good map-level definition.
