The Art of the Intimate Scale
Chapter 6: The 18th-Century Boom
Ivory, Cosway & the Portrait Miniature's Commercial Golden Age
The 18th century was the portrait miniature's commercial golden age — the period when it became not merely a courtly luxury but a mass market product, available to the prosperous middle classes, worn on the body, exchanged between lovers, and produced in enormous quantities by a thriving industry of professional limners.
Rosalba Carriera and the Ivory Revolution
The transformation of 18th-century miniature painting began in Venice with Rosalba Carriera (1673–1757), who pioneered the use of ivory as a substrate around 1700. The impact was immediate and irreversible. Ivory's natural translucency, when combined with thin watercolour washes, produced a luminosity that vellum could never achieve — a warm, inner glow that seemed to radiate from within the portrait itself, ideally matching the warm translucency of human skin.
Carriera's innovation swept through European miniature painting within a generation. By 1750, ivory had almost entirely replaced vellum as the primary support. The watercolour miniature on ivory became the defining technology of 18th-century portraiture.

Richard Cosway: The Supreme 18th-Century Miniaturist
In England, the supreme practitioner of the ivory miniature was Richard Cosway (1742–1821). His style — limpid, luminous, elegantly unfinished, with much of the ivory left unpainted to provide the high-key brightness of his portraits — became the defining aesthetic of fashionable late 18th-century miniature painting. He was the most fashionable portrait miniaturist in London, painting the Prince of Wales, the Duchess of Devonshire, and virtually every figure of consequence in British society.
Cosway's technique exploited the ivory support with extraordinary sophistication. Rather than covering the surface with opaque pigment (as earlier vellum painters had done), he worked with transparent washes and the dry stipple technique, allowing the warm ivory ground to breathe through the paint layers. The result was portraits of ethereal, almost weightless beauty.
The Social Life of the 18th-Century Miniature
The 18th century transformed the social function of the miniature. What had been primarily a courtly and diplomatic object in the Tudor and Stuart periods became a far more widely distributed form of personal expression. The development of the locket — a hinged case that could be worn as jewellery — made the miniature a standard feature of fashionable dress. Miniatures were exchanged between lovers, given by parents to children departing for long journeys, and worn by military officers carrying portraits of wives and sweethearts into battle.
The reverse sides of miniatures became increasingly elaborate: woven hair — of the sitter, or of a deceased loved one — was mounted under glass in intricate patterns, sometimes combined with painted mourning imagery (urns, weeping willows, classical tombs). This transformed the miniature into a secular relic: a physical piece of the person, to be held and kissed.
Continental Traditions: France, Germany, and Scandinavia
The 18th-century boom was not exclusively British. France produced Jean-Baptiste Isabey, whose exquisitely finished portraits in the Napoleonic period represented a different but equally distinguished tradition. The Swedish miniaturist Adolf Ulrik Wertmüller worked across Scandinavia and America. The German tradition, centred on Dresden and Vienna, produced a school of enamel miniaturists of extraordinary technical refinement.

������ The President's Edge
The 18th-century miniature as mourning object — incorporating the actual hair of the deceased — is the detail that most moves modern audiences. It transforms the miniature from a luxury object into an intimate memorial: a secular relic in the most precise sense. This dimension of the form resonates powerfully in any discussion of the miniature's unique relationship to mortality and memory.
