Introduction to Archaeological Artifact Identification

Archaeological artifacts provide tangible connections to our human past, telling stories of ancient civilizations, technologies, and cultural practices. Whether you’ve found an unusual object while gardening, inherited a family collection, or wish to begin collecting cultural artifacts responsibly, proper identification is essential for understanding historical significance and determining authenticity and value.

In this comprehensive guide, we’ll explore professional techniques for archaeological artifact identification, covering everything from basic visual assessment to advanced scientific methods. You’ll learn how to recognize key characteristics of common artifact types, understand authentication processes, and navigate the ethical and legal considerations of artifact collection and ownership.

Proper identification of archaeological artifacts serves multiple critical purposes:

1. Historical understanding: Correctly identified artifacts provide insights into human history, technological development, and cultural practices
2. Authentication: Distinguishes genuine artifacts from reproductions or fraudulent items
3. Preservation: Enables appropriate conservation techniques based on material composition
4. Legal compliance: Helps determine if artifacts are subject to ownership restrictions or repatriation laws
5. Valuation: Establishes fair market value for insurance, donation, or sale purposes

Basic Tools and Equipment for Artifact Identification

Before examining potential archaeological artifacts, having the right tools will significantly improve your identification capabilities. While professional archaeologists and conservators have access to sophisticated laboratory equipment, collectors and enthusiasts can use these basic tools to conduct initial assessments:

For more advanced examination, specialized equipment may be necessary, though these typically require professional training to use effectively:

• UV (ultraviolet) light for detecting repairs or modern materials
• Microscope for examining material composition and manufacturing techniques
• XRF (X-ray fluorescence) analyzer for non-destructive elemental analysis
• CT (computed tomography) scanner for examining internal structures

Remember that certain tests that involve sampling or potentially damaging artifacts should only be conducted by trained professionals, especially for items of significant historical or monetary value.

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

Stone Tools and Lithics

Stone tools represent some of the most common and enduring archaeological artifacts, spanning human history from the earliest Paleolithic implements to more recent Native American tools. Key identification factors include:

Types of Stone Tools:

• Projectile points (arrowheads, spear points)
• Scrapers for hide preparation
• Knives for cutting
• Drills for creating holes
• Axes and adzes for woodworking
• Grinding stones for food processing

Identification Characteristics:

• Material type: Common materials include flint, chert, obsidian, quartzite
• Manufacturing technique: Look for flaking patterns, grinding marks, or polishing
• Shape and design: Different cultures and time periods have distinct typologies
• Use-wear: Microscopic edge damage can indicate how the tool was used
• Patina: Surface weathering that develops over time

Dating Considerations: Stone tools are typically dated by their typology (design characteristics) and archaeological context rather than direct dating methods, though obsidian can be dated using obsidian hydration analysis.

Ceramics and Pottery

Pottery fragments (sherds) are abundant at many archaeological sites and provide valuable information about past societies:

Types of Ceramic Artifacts:

• Vessels: Bowls, jars, cups, plates
• Figurines: Human and animal representations
• Architectural elements: Tiles, bricks, drainage pipes
• Ceremonial objects: Ritual vessels, incense burners

Identification Characteristics:

• Clay composition: Color, texture, inclusions (temper)
• Manufacturing technique: Hand-built, wheel-thrown, mold-made
• Surface treatments: Glazes, slips, burnishing, painting
• Decoration: Incising, stamping, painting, appliqué
• Firing method: Oxidation (bright colors) vs. reduction (darker colors)
• Form: Rim, body, or base fragment; overall vessel shape if intact

Dating Considerations: Ceramics can be dated through thermoluminescence testing, contextual analysis, and stylistic comparison to established chronologies.

Metal Artifacts

Metal artifacts appear later in human history and range from simple tools to elaborate ornamental pieces:

Types of Metal Artifacts:

• Tools and weapons: Knives, arrowheads, axes
• Personal adornment: Jewelry, clasps, buttons
• Coins: Various currencies throughout history

Organic Materials

Organic artifacts survive only in specific preservation environments but provide unique insights when found:

Types of Organic Artifacts:

• Textiles: Clothing, bags, mats, cordage
• Wooden objects: Tools, containers, architectural elements
• Bone and antler: Tools, ornaments, ritual objects
• Plant remains: Seeds, fibers, food residues

Identification Characteristics:

• Material source: Animal vs. plant; species identification
• Manufacturing method: Weaving, carving, drilling techniques
• Use-wear: Polishing, staining, breakage patterns
• Preservation condition: Often fragile and requiring special handling

Dating Considerations: Organic materials can often be directly dated using radiocarbon (C14) dating methods.

The market for archaeological artifacts unfortunately includes numerous reproductions, fakes, and fraudulent items. Understanding common red flags can help you avoid misidentifications and fraudulent purchases:

Common Signs of Reproduction or Fraud

Visual Indicators:

• Uniform patina without natural variation
• Too perfect or pristine condition for claimed age
• Machine-made marks on supposedly ancient items
• Inconsistent wear patterns that don’t match actual use
• Modern materials like contemporary glues or fillers
• Artificial aging techniques like chemical treatments or staining

Contextual Red Flags:

• Vague provenance or changing story about origin
• Price too good to be true for the type of artifact
• Seller unwilling to provide documentation or authentication
• Sudden appearance of multiple similar “rare” items
