A sherd can preserve rim form, fabric, slip, paint, or maker evidence, but an undocumented fragment may have little responsible market context.
- Photograph the whole object, front, back, base, interior, edges, breaks, marks, mounts, labels, and associated documents.
- Record dimensions, weight, material, construction, surface, condition, repairs, seller, location, and every provenance statement exactly.
- Separate observed facts from attribution, family history, dealer language, translation, and collector labels.
- Compare museum objects, excavation reports, typologies, scientific evidence, old catalogs, and lawful collection records.
- State identity, date, origin, authenticity, and legal status only as strongly as the evidence supports.
Historical frame
A sherd can preserve rim form, fabric, slip, paint, or maker evidence, but an undocumented fragment may have little responsible market context. Function should be inferred from form, wear, residue, context, inscriptions, parallels, and manufacturing evidence rather than a seller’s imaginative use-story.
Identification evidence
For pottery sherds, record complete dimensions, material, forming method, joins, tooling, decoration, residues, wear, repairs, labels, and modern mounts. Compare complete profiles and technical details, not just frontal appearance.
Authenticity traps
Watch for modern casts, altered fragments, composites, false patina, added decoration, restored profiles, and authentic-looking material used to manufacture a new pottery sherds.
Condition and preservation
Avoid aggressive cleaning, oil, acid, wire brushing, household polish, soaking, and adhesive repair. Isolate unstable corrosion, flaking surfaces, salts, active mold, and fragile organic materials until a qualified conservator can advise.
Value and market research
Responsible value research begins only after lawful title, attribution, authenticity, completeness, restoration, condition, provenance, publication history, and comparable sales are understood. A legally risky object may be unsalable regardless of appearance.
Compare documented collector listings
Use listings to study measurements, material, form, restoration, documentation, seller language, and market supply. Do not treat an asking price or a certificate alone as proof.
