<span>Examining Construction Techniques</span>
</h2>
<div class="section-header__body">The way a piece of furniture is constructed offers significant clues about its age and authenticity. Hand-crafted techniques used before the industrial revolution differ substantially from machine-made methods.</div>
Joinery Methods
One of the most telling indicators of an antique piece is its joinery—how the different parts of the furniture are connected. Here are key joinery features to examine:
Dovetail Joints
Dovetail joints are found in quality furniture, especially in drawers. In antiques:
Hand-cut dovetails (pre-1890s) are slightly irregular and uneven
Each dovetail is unique in size and spacing
Early dovetails were often larger and more widely spaced
Machine-cut dovetails (post-1890s) are perfectly uniform
Mortise and Tenon Joints
Look for mortise and tenon joints in the structural parts of the furniture:
In antiques, these joints were hand-cut and often secured with wooden pegs
Examine chair legs, table supports, and frame connections
Loose tenons might indicate an older piece that has weakened over time
Other Joinery Clues
Kerf marks (saw marks) that are uneven suggest hand-sawing
Look for signs of hand planing on unexposed areas
Check for animal glue residue in the joints (it appears amber-colored)
Tool Marks and Craftsmanship
Examine the underside, back, and hidden areas of the furniture:
Irregular tool marks indicate hand tools rather than machinery
Plane marks, chisel marks, or adze marks suggest hand crafting
Perfectly smooth surfaces likely indicate modern machine planing
Slight asymmetry is common in handcrafted antiques
Look for the drawknife or spokeshave marks on curved elements

<span>Wood Types and Characteristics</span>
</h2>
<div class="section-header__body">The type of wood used, how it was cut, and its aging patterns can provide crucial information about a piece’s age and origin.</div>
Common Woods in Antique Furniture
Different periods favored different types of wood:
Oak: Dominant in the 16th and 17th centuries, especially in English and American furniture
Walnut: Popular in the 18th century, particularly in Queen Anne and Chippendale styles
Mahogany: Became fashionable in the mid-18th century through the 19th century
Cherry: Common in American furniture from the late 18th to 19th centuries
Rosewood: Popular during the Victorian era (mid-to-late 19th century)
Pine and other secondary woods: Often used for structural elements and drawer bottoms
Secondary Woods
Examine less visible parts like drawer bottoms, backing boards, and internal framing:
High-quality antiques often used different woods for visible and non-visible parts
Secondary woods were typically local, inexpensive varieties
American furniture might use pine, poplar, or tulip wood for secondary parts
European pieces might use oak, beech, or other regional woods
The type of secondary wood can help identify the region of origin
Wood Cut and Aging Characteristics
Examine how the wood was cut and how it has aged:
Look for irregular circular saw marks (post-1830s) versus straight saw marks (earlier hand sawing)
Handmade furniture often shows inconsistent thickness in panels
Natural darkening and color changes occur with age
True patina can’t be faked—it’s a combination of oxidation, UV exposure, handling oils, and time
Wood shrinkage: antique solid wood typically shows some warping or shrinkage
Quarter-sawn wood (showing “tiger stripes” or “flecking”) was common in certain periods

<span>Hardware and Metal Components</span>
</h2>
<div class="section-header__body">The hardware used in furniture has evolved significantly over time, making it one of the most reliable indicators for dating a piece.</div>
Nails and Screws
These fasteners can provide precise clues about when a piece was made:
Hand-forged nails (pre-1800s): Irregular with a rosehead or L-head, tapered on all four sides
Cut nails (1790s-early 1900s): Machine-cut from iron sheets, uniform in width but tapered from two sides only
Wire nails (post-1890s): Round, uniform diameter, machine-made
Machine-made screws with pointed tips (after 1848)
Completely standardized Phillips head screws (post-1930s)
Hinges, Pulls, and Locks
Original hardware provides important dating clues:
H or HL hinges: Common in the 17th and early 18th centuries
Butt hinges: Became common after 1820
Pulls and handles: Style evolved significantly:
Simple turned wood knobs (early periods)
Bail handles with back plates (18th-19th centuries)
Stamped brass (Victorian era)
Cast metal (late 19th century)
Locks: Look for hand-forged lock mechanisms versus machine-made
Metal Patina and Aging
Authentic antique hardware will show consistent aging:
Natural verdigris on brass
Worn areas from repeated handling
Even oxidation patterns
Signs of hand-forging in early pieces
Look for replaced hardware, which may indicate repairs
