<div class="section-header__body">Archaeologists use a combination of visual assessment, contextual information, and scientific analysis to identify and authenticate artifacts.</div>

Artifact identification generally follows a systematic process that combines visual examination, contextual information, and, when necessary, scientific testing. Here’s a practical approach to identifying potential archaeological artifacts:

1. Document Provenance

Before physical examination, record all known information about the artifact’s origin:

  • Where was it found? (Precise location if possible)
  • When was it discovered?
  • What was the context of discovery? (Depth, surrounding materials, etc.)
  • Ownership history (if purchased or inherited)

Provenance is critical not only for identification but also for establishing authenticity and legal ownership. An artifact with well-documented provenance has both greater historical value and typically higher market value.

2. Visual Examination and Documentation

Begin with non-invasive visual assessment:

  1. Photograph the artifact from multiple angles with good lighting and scale reference
  2. Measure dimensions (length, width, thickness) using calipers
  3. Weigh the artifact using a precise scale
  4. Note the material composition (stone, ceramic, metal, bone, etc.)
  5. Document distinctive features like decorations, markings, or wear patterns
  6. Examine manufacturing techniques (hand-carving, wheel-thrown pottery, etc.)
  7. Look for signs of age (patina, wear patterns, soil deposits)

3. Comparative Analysis

Compare your findings with established knowledge:

  • Reference books and archaeological guides
  • Museum collections (many have online databases)
  • Academic publications on similar artifacts
  • Archaeological society resources

4. Scientific Testing (Professional Level)

For valuable or significant artifacts, professional testing may be warranted:

  • Radiocarbon dating for organic materials (bone, wood, textiles)
  • Thermoluminescence testing for ceramics
  • XRF analysis for determining metal composition
  • Microscopic examination of manufacturing techniques

5. Expert Consultation

When in doubt, consult with experts:

  • University archaeology departments
  • Museum curators
  • State archaeological offices
  • Professional archaeological societies
  • Reputable artifact dealers who specialize in authenticated pieces

  • Lack of documented provenance

For valuable items, professional authentication is strongly recommended, potentially including scientific testing like thermoluminescence for ceramics or metallurgical analysis for metal artifacts. Remember that modern reproductions can be extremely sophisticated, making expert assessment invaluable.

How are archaeological artifacts dated?

Archaeological artifacts are dated through several complementary methods:

Absolute Dating Methods:

  • Radiocarbon (C14) Dating - For organic materials up to ~50,000 years old
  • Thermoluminescence - For ceramics and fire-affected stones
  • Dendrochronology - Tree ring dating for wooden artifacts
  • Potassium-Argon Dating - For very ancient materials (volcanic contexts)
  • Archaeomagnetic Dating - For fired clay materials

Relative Dating Methods:

  • Stratigraphy - Dating based on soil layers
  • Seriation - Arranging artifacts by stylistic changes over time
  • Typology - Classification based on established chronologies
  • Cross-dating - Correlating with items of known date
  • Associated context - Dating through relationship to datable materials

Professional archaeologists typically use multiple dating methods to establish the most accurate chronology. For collectors, typological dating (comparing to established chronologies) is often the most accessible method without scientific testing.

What factors determine the value of archaeological artifacts?

The value of archaeological artifacts (for legally owned items) is influenced by:

  1. Authenticity - Confirmed genuine artifacts command higher prices
  2. Rarity - Uncommon artifact types or cultures are more valuable
  3. Condition - Complete, well-preserved examples are worth more
