The Allure of Tiffany Lamps
Before delving into the specifics of spotting fakes, it’s important to appreciate what makes Tiffany lamps so special. Tiffany Studios, operating from the late 19th century through the early 20th century, produced lamps that were not merely sources of light but works of art. Each lamp was a unique creation, painstakingly assembled by skilled artisans. The intricate designs, vibrant color palettes, and the masterful way light played through the glass captivated the public then and continues to do so today. The quality of Tiffany Studios glass itself is legendary, possessing a depth and luminescence rarely replicated.
Deciphering Authenticity: Key Indicators of a Genuine Tiffany Lamp
Authenticating a Tiffany lamp is a multi-faceted process, requiring attention to detail across several key areas. Genuine Tiffany lamps bear the hallmarks of superior craftsmanship and artistic integrity.
1. The Tiffany Signature: Lamp Signature Verification
One of the most crucial, though not solely definitive, indicators is the presence of a signature. Authentic Tiffany lamps are typically signed.
Types of Signatures:
- “Tiffany Studios”: This is a common signature found on many genuine pieces. It might be cast into the metal base or etched onto the glass itself.
- “Tiffany & Co.”: Sometimes, especially on earlier pieces or those directly associated with the retail store, you might see this signature.
- “L.C.T.”: Often found on Favrile glass, this signature indicates the work of Louis Comfort Tiffany himself.
- “L.C.T. Favrile”: This signifies that the glass used in the lamp is Tiffany’s proprietary Favrile glass.
Where to Look for Signatures:
- On the Lamp Base: Check the underside of the base, often cast directly into the metal. Look for raised or incised lettering.
- On the Metal Hub: The metal ring that secures the glass shade might also bear a signature.
- On the Glass Itself: Some signatures are etched or enameled directly onto the glass, often on a less visible part of the shade.
Important Note: While a missing signature doesn’t automatically mean a lamp is fake (some were unsigned due to manufacturing variations or damage over time), its presence, when correctly executed, is a strong indicator of authenticity. Conversely, a poorly executed, hastily applied, or incorrect signature is a significant red flag.
2. Examining the Tiffany Lamp Construction
The way a Tiffany lamp is constructed speaks volumes about its authenticity. Tiffany artisans were masters of their craft, and their techniques are evident in the finished product.
The Metalwork:
- Patina: Genuine Tiffany lamp bases are typically made of bronze and often feature a rich, deep patina that has developed over time. Reproductions may have a brassy or painted finish that looks artificial. The patina on genuine lamps is usually a deep brown, black, or green, with a subtle sheen.
- Molding and Casting: The metalwork should be precisely molded and cast. Look for crisp details, smooth transitions, and a well-finished appearance. Rough edges, visible seams from casting, or a lack of fine detail can indicate a reproduction.
- Weight: Tiffany bases are generally substantial and heavy, reflecting the quality of the bronze used. A lightweight base might be made of a less dense metal or even resin.
The Glass Shade:
- Quality of Glass: Tiffany Studios glass is renowned for its exceptional quality. Genuine Tiffany glass often has an iridescent sheen, with subtle color variations and depth. It’s not just dyed glass; the color is inherent to the glass itself.
- Color Granulation: True Tiffany glass often exhibits a subtle “granulation” or a slightly uneven texture when held up to the light, a result of the glassmaking process. Reproductions might have a perfectly smooth, uniform surface.
- Soldering: The glass pieces in a Tiffany shade are held together by copper foil and solder. Genuine Tiffany soldering is meticulously done, with fine, even solder lines that are almost invisible in places. The solder lines should have a consistent color (often a dark grey or black) and a smooth finish. Poorly applied, bulky, or uneven solder lines are a common giveaway of fakes.
- Glass Fit: The individual glass pieces should fit together seamlessly, with minimal gaps. The soldering is intended to outline the design, not fill in large spaces.
- Iridescence: Many Tiffany lamps feature iridescent glass, particularly in the Favrile line. This iridescence is a lustrous, shifting quality that appears on the surface of the glass, often in rainbow hues. It should look like an integral part of the glass, not a coating.
3. Identifying Tiffany Lamp Patterns and Designs
The iconic nature of Tiffany lamps lies in their intricate and often nature-inspired designs. Recognizing these patterns is key.
Common Motifs:
- Floral: Flowers like lilies, poppies, dragonflies, orchids, and irises are prevalent.
- Geometric: Intricate geometric patterns, often in abstract or stylized forms.
- Figural: Less common but present, featuring human or animal forms.
- Mosaics: Lamps with designs created using small pieces of glass like a mosaic.
Design Execution:
- Color Blending: Tiffany artisans were masters at blending colors within a single piece of glass or transitioning colors seamlessly between pieces. Look for nuanced color transitions rather than abrupt shifts.
- Glass Opacity and Transparency: Genuine Tiffany lamps often utilize a mix of opaque and translucent glass to create depth and visual interest. Reproductions might rely heavily on uniformly translucent glass.
- Originality: While Tiffany Studios produced many popular designs, they also created unique, one-of-a-kind pieces. Familiarize yourself with known Tiffany designs to spot unusually derivative or uninspired patterns.
4. The Importance of Base and Finial Design
Don’t overlook the details of the lamp’s base and finial (the decorative cap on top of the shade).
- Base Styles: Tiffany bases came in various styles, often incorporating naturalistic forms like tree trunks, vines, or organic shapes. The quality of the casting and the detail in these forms are crucial.
- Finials: The finial should complement the overall design of the lamp. It might be a stylized flower, a simple bronze cap, or incorporate glass elements. The material and craftsmanship of the finial should match the rest of the lamp.
5. Examining the Overall Condition and Age
The age and condition of a lamp can also provide clues.
- Wear and Tear: Genuine antique Tiffany lamps will show signs of age. This might include minor chips or wear on the glass, patina variations on the metal, or slight imperfections in the solder. However, extensive damage or easily replaceable parts can be a concern.
- Wiring: Older lamps will have older wiring. If the wiring looks too new or has been recently replaced with modern wiring, it might indicate that the lamp has been significantly altered or is a reproduction. Conversely, very old, brittle wiring on an otherwise pristine lamp could also raise questions.
- Provenance: If available, provenance (the history of ownership) can be a strong indicator of authenticity. Documents, old photographs, or previous sales records can help verify a lamp’s history.
When to Seek an Antique Tiffany Lamp Appraisal
If you have a lamp that you believe might be a genuine Tiffany, or if you’re considering purchasing a potentially valuable piece, an antique Tiffany lamp appraisal is highly recommended.
Why Appraisals are Crucial:
- Expert Opinion: Certified appraisers have specialized knowledge of Tiffany lamps, their history, and the market.
- Authenticity Verification: They can identify subtle signs of forgery that a layperson might miss.
- Valuation: An appraisal will provide an accurate estimate of the lamp’s Tiffany lamp value, which is essential for insurance, sale, or estate planning.
- Identifying Restorations: An appraiser can also identify any repairs or restorations that might affect the lamp’s value.
What an Appraiser Will Consider:
- Signature: As discussed, the presence and authenticity of the signature.
- Glass Quality and Design: The type, color, and craftsmanship of the glass.
- Metalwork: The material, patina, and casting quality of the base and hardware.
- Construction: The soldering, fit of the glass pieces, and overall assembly.
- Rarity of the Pattern: Some designs are much rarer and more valuable than others.
- Condition: Any damage, wear, or previous repairs.
- Provenance: Documented history of ownership.
Common Red Flags for Fake Tiffany Lamps
Being aware of common pitfalls can save you from making an expensive mistake.
Table: Spotting Reproductions – Red Flags to Watch For
| Feature | Genuine Tiffany Lamp Indicator | Reproduction Indicator |
|---|---|---|
| Signature | Clearly executed, consistent with known Tiffany signatures, often in appropriate locations. | Poorly formed, misspelled, looks stamped or added later, in unusual locations, missing. |
| Glass | High quality, subtle color variations, iridescence inherent to the glass, good light diffusion. | Uniform color, painted-on color, lacks depth or iridescence, appears “plastic-like.” |
| Soldering | Fine, even, consistent color, minimal gaps between glass pieces. | Bulky, uneven, rough, too much solder, inconsistent color, visible gaps filled with solder. |
| Metalwork | Rich patina, finely cast details, substantial weight, smooth finish. | Brassy or painted finish, rough casting, lightweight, visible mold lines. |
| Design | Intricate, well-executed, harmonious color transitions, consistent with known Tiffany motifs. | Garish colors, poorly executed patterns, uninspired designs, disproportionate elements. |
| Base | Solid construction, detailed casting, appropriate weight. | Hollow or lightweight construction, rough casting, generic appearance. |
| Wiring | Age-appropriate for the era of production. | Looks brand new and modern on an otherwise “antique” lamp, or excessively brittle and unsafe. |
The Tiffany Lamp Value Factor
The Tiffany lamp value is determined by a confluence of factors. Rarity is paramount; a lamp with a unique or seldom-seen design will command a higher price than a more common model. The quality of the glass and the intricacy of the leaded or foiled design also play a significant role. Condition is another critical element; a lamp in excellent original condition will always be worth more than one that has been heavily repaired or restored. Finally, the provenance and the presence of authentic genuine Tiffany lamp markings greatly influence its desirability and market price.
Frequently Asked Questions (FAQ)
Q1: Are all lamps with Tiffany-style shades genuine Tiffany lamps?
A1: No. “Tiffany-style” refers to lamps that mimic the aesthetic of Tiffany lamps, often made with similar techniques but lacking the authentic Tiffany Studios craftsmanship, materials, and signature. Many companies have produced Tiffany-style lamps for decades.
Q2: Can a lamp be genuine Tiffany if it doesn’t have a visible signature?
A2: It’s possible, but less likely. Some early Tiffany lamps or specific types might not have been signed. However, a lack of signature makes authenticity harder to verify and can impact the lamp’s value.
Q3: How can I clean my Tiffany lamp without damaging it?
A3: For the glass shade, gently dust with a soft brush or cloth. If it needs more cleaning, use a damp, soft cloth with mild soap and water, then dry thoroughly. For the metal base, consult with a professional restorer if it needs significant cleaning, as harsh chemicals can damage the patina. Avoid abrasive cleaners on both the glass and metal.
Q4: Where can I find reliable information on identifying Tiffany lamp patterns?
A4: Books by reputable Tiffany scholars, museum collections, and specialized antique dealers are excellent resources. Many auction house catalogs also feature detailed descriptions and photographs of genuine Tiffany lamps.
Q5: Is it worth buying a reproduction Tiffany lamp?
A5: Reproduction Tiffany-style lamps can be beautiful and affordable decorative items. However, they are not investments in the same way genuine Tiffany lamps are, and their value will not appreciate similarly. The decision depends on your purpose – decoration versus collecting and investment.
By approaching the task of stained glass lamp authenticity with diligence and an informed eye, you can confidently identify genuine Tiffany lamps and appreciate the enduring artistry of Louis Comfort Tiffany and his studio. Remember, when in doubt, always seek the expertise of a qualified appraiser.
