Louis Comfort Tiffany: Favrile Glass and the American Vision — A Collector's Guide

Part of The Wonder Room's series on Art Nouveau & Art Deco Glass. Read the pillar guide for the full historical and design context.

Introduction

Louis Comfort Tiffany is the most celebrated name in American decorative art, a designer of extraordinary range and ambition whose work in glass transformed the medium and created objects that remain, more than a century after they were made, among the most recognisable and most desired in the world.

His leaded glass lamps, the dragonfly, the wisteria, the peony, the magnolia, have achieved a cultural visibility that few decorative art objects can match. But Tiffany was far more than the maker of famous lamps. His blown Favrile glass, his windows, his interiors, and his broader decorative arts practice represent one of the most sustained and coherent artistic visions of the Art Nouveau period, and the full range of his achievement rewards serious study.

This guide introduces Tiffany's life and work, his principal techniques and ranges, and what collectors need to know when approaching the market today, including the critical question of distinguishing authentic Tiffany from the many imitations and misattributions that the market has always generated.

Life and Formation

Louis Comfort Tiffany was born in 1848 in New York, the son of Charles Lewis Tiffany, founder of the celebrated jewellery house. He trained as a painter, studying in New York and Paris, before turning to the decorative arts in the 1870s. His formation as a painter was decisive: throughout his career, his primary concern was colour and light, and his approach to glass was always that of a colourist rather than a craftsman.

He travelled extensively in Europe and North Africa in the 1860s and 1870s, and the influence of Islamic art, its rich colour, its geometric ornament, its mastery of light through coloured glass, is evident throughout his work. He was also deeply influenced by Japanese art, which he encountered through the wave of japonisme that swept the Western decorative arts in the 1870s and 1880s.

Tiffany established his decorating firm, initially called Louis C. Tiffany and Associated Artists, in 1879, and quickly built a reputation for interior decoration of the highest quality. His commissions included the Veterans' Room of the Seventh Regiment Armory in New York and, most famously, the redecoration of the White House reception rooms for President Chester Arthur in 1882.

His engagement with glass as a primary medium deepened through the 1880s, and in 1893 he established the Tiffany Glass and Decorating Company, which became the vehicle for his most celebrated work. The Tiffany Studios, as the enterprise was eventually known, operated until 1933, when it was forced into bankruptcy by the Depression.

Favrile Glass: The Iridescent Vision

The technique most closely associated with Tiffany's blown glass is Favrile, a term he coined from the Old English word fabrile, meaning handmade. Favrile glass achieves its extraordinary iridescent surface through the introduction of metallic oxides, typically compounds of gold, silver, or iron, into the glass during the blowing process, or through the application of metallic vapours to the surface of the hot glass.

The result is a surface that shifts colour in the light, from gold to green to blue to amber, with a quality that Tiffany described as resembling the wing of a butterfly or the surface of a soap bubble. The effect is unlike anything achievable by other means, and it remains one of the most beautiful surface treatments ever applied to glass.

Tiffany was not the inventor of iridescent glass, the Bohemian glasshouse Loetz had been producing iridescent work since the early 1890s, and the two studios' output is frequently confused by inexperienced collectors, but he developed the technique to a level of refinement and artistic expression that was entirely his own.

Gold Favrile

The most celebrated Favrile pieces are those in gold, a warm, lustrous amber-gold that is the colour most associated with Tiffany's name. Gold Favrile vases, in the organic, plant-derived forms that Tiffany favoured, are among the most beautiful objects of the Art Nouveau period and among the most consistently sought-after in the collector market.

Blue Favrile

Blue Favrile, in which the iridescent surface plays over a deep cobalt or peacock blue ground, is rarer than gold and generally more valuable. The finest blue Favrile pieces have a depth and richness of colour that is extraordinary, and they are some of the most desirable objects in the entire Tiffany canon.

Paperweight Vases

Among the most technically demanding of Tiffany's blown glass pieces, paperweight vases feature internal decoration, flowers, leaves, and other natural subjects,worked in coloured glass and encased within the body of the vessel. The technique is related to the Graal process developed at Orrefors, and the finest examples are objects of extraordinary complexity and beauty. They are rare and valuable Tiffany pieces.

Reactive and Special Glass

Tiffany's glassmakers developed a range of special glass types, reactive glasses that change colour when reheated, glasses with internal texture or pattern, glasses that combine multiple colours in a single gather, that were used both in blown pieces and in the leaded lamp shades. These special glasses are a significant part of Tiffany's technical achievement and a key element of the visual richness of his work.

Leaded Glass Lamps: The Celebrated Masterworks

Tiffany's leaded glass lamps are the objects for which he is most widely known, and they are among the most celebrated decorative art objects ever made. The technique, in which hundreds or thousands of pieces of coloured glass are cut to shape and joined with lead came to form a pictorial or decorative composition, was not invented by Tiffany, but he developed it to a level of artistic ambition and technical refinement that no one before or since has matched.

The Great Designs

The most celebrated Tiffany lamp designs, the Wisteria, the Dragonfly, the Peony, the Magnolia, the Laburnum, the Cobweb, are some of the most recognisable objects in the history of decorative art. Each design exists in multiple sizes and colourways, and the finest examples, with the richest colour, the most complex leading, and the most carefully selected glass, are objects of extraordinary beauty.

These lamps were designed not by Tiffany himself but by a team of designers working under his direction, most notably Clara Driscoll, whose role in creating many of the most celebrated designs was long unrecognised. Driscoll led the Women's Glass Cutting Department at Tiffany Studios and is now credited with the design of the Dragonfly, the Peony, and several other major lamp designs.

Geometric Lamps

Alongside the naturalistic designs, Tiffany Studios produced a large range of geometric lamps, in which the leaded glass composition is based on geometric pattern rather than naturalistic imagery. These lamps are generally less celebrated than the great naturalistic designs but are often of comparable technical quality and can represent better value for collectors who want the Tiffany aesthetic at a more accessible price point.

Bases

Tiffany lamp bases, typically in bronze, often with surface patination in green, brown, or gold, are an integral part of the design and contribute significantly to the value of a complete lamp. Original bases with their original shades are the most desirable; mismatched combinations, a Tiffany shade on a non-Tiffany base, or vice versa, are less so. The base should always be examined as carefully as the shade.

Windows and Architectural Glass

Tiffany's leaded glass windows, produced for churches, public buildings, and private residences across America, represent some of his most ambitious and most beautiful work. The scale and complexity of the finest windows, in which thousands of pieces of specially selected and treated glass are assembled into compositions of great pictorial and decorative richness, is extraordinary, 

Individual window panels and fragments occasionally appear on the market and are highly collectible. Complete windows are rarely available and command exceptional prices.

Tiffany vs Loetz: The Attribution Question

One of the most common challenges facing collectors of Art Nouveau iridescent glass is distinguishing between Tiffany Favrile and the iridescent glass produced by the Bohemian glasshouse Loetz Witwe. The two studios were contemporaries, both producing iridescent glass of high quality, and their output is frequently confused, sometimes innocently, sometimes not.

The key distinctions are as follows. Tiffany Favrile is typically signed on the base with an engraved signature (see below); Loetz pieces are less consistently marked. Tiffany's forms tend to be more organic and plant-derived; Loetz forms are often more geometric or architecturally influenced, reflecting the studio's relationship with the Wiener Werkstätte. Tiffany's iridescence tends to be warmer and more golden; Loetz iridescence is often cooler and more silvery, with a wider range of surface effects.

That said, the finest Loetz pieces are objects of genuine beauty and considerable value in their own right, and the collector who learns to appreciate both studios will find the Loetz market, where misattribution has historically suppressed prices, a rewarding hunting ground.

Signatures and Marks

Tiffany pieces are typically signed, and the form of the signature is an important guide to authenticity and dating.

L.C. Tiffany – Favrile — the standard signature on blown glass pieces, engraved into the base. Often accompanied by a catalogue number (e.g. A1234 or 1234A) that can be cross-referenced with Tiffany Studios records.

L.C.T. — an abbreviated form of the signature, used on smaller pieces where space is limited.

Tiffany Studios New York — the mark used on lamp bases and other bronze pieces, typically cast or stamped into the metal.

Tiffany Studios New York [number] — lamp shades are typically marked with the studio name and a design number, which can be used to identify the specific design.

Unsigned pieces attributed to Tiffany should be treated with great caution. The Tiffany market is one of the most heavily faked in the decorative arts, and the presence of a signature, while necessary, is not sufficient on its own to guarantee authenticity. Buy from reputable dealers, seek specialist advice for significant purchases, and consult the published literature before committing.

What to Look For When Buying

Authenticity first — The Tiffany market is heavily faked. Signatures can be added to non-Tiffany pieces; lamp shades can be assembled from non-Tiffany glass; bases can be married to non-original shades. Buy from reputable sources and seek specialist advice for any significant purchase.

Glass quality in lamps — The quality of the glass in a leaded lamp shade is the primary determinant of its beauty and value. Look for richness and variety of colour, for the use of special glass types (striated, reactive, textured), and for the precision and consistency of the leading. The finest shades have a luminosity when lit that is quite unlike anything achievable with lesser glass.

Favrile colour — In blown Favrile pieces, blue is rarer and more valuable than gold; unusual colours and surface effects command premiums. The quality of the iridescence, its depth, its range of colour shift, its evenness, is a primary quality indicator.

Form — Tiffany's blown glass forms are organic and plant-derived, the best pieces have a quality of growth and movement that reflects his painter's eye. Stiff or mechanical forms are a warning sign.

Condition — In lamps, check for replaced glass panels, re-leading, and repairs to the shade. In blown pieces, check rims and bases for chips. The bronze bases of lamps should have their original patination; re-patinated bases are less desirable.

Provenance — For significant pieces, a clear ownership history adds confidence. Original Tiffany Studios receipts or documentation are rare but extremely valuable when they exist.
