Most people who use the word "lacquer" mean a glossy paint or a synthetic varnish. Real lacquer is something else entirely — a natural material with a three-thousand-year history, made from the sap of a single tree species, applied by hand over months. Here is what the word actually refers to, and why work made this way has outlasted empires.
What lacquer actually is
True lacquer is the sap of trees in the family Anacardiaceae — most often Toxicodendron vernicifluum in Japan and China, and Gluta laccifera in Cambodia and Vietnam. The sap is harvested by hand, filtered, gently heated, and aged before it can be used. Once applied to a surface, it cures not by drying but by oxidative polymerisation — a slow molecular reaction that requires high humidity to complete. The result is a hard, water-resistant, food-safe polymer of extraordinary durability.
This material is not a coating. It is a structure. A finished lacquer surface is built from twenty to fifty individual cured layers, each a few microns thick, accumulated over weeks or months. Light entering the surface travels through several of these layers before returning to the eye, which is why genuine lacquer carries a depth that synthetic finishes cannot reproduce.
What it is not
The word "lacquer" is loosely applied in modern interior design to glossy paints, polyurethane coatings, automotive clear-coats, and nail varnish. None of these are lacquer in the traditional sense. They are synthetic resins that mimic the appearance of natural lacquer in minutes rather than months. They look superficially similar; they behave very differently. Polyurethane yellows and crazes within decades. Cured natural lacquer remains stable for centuries.
A short history
The earliest known lacquerware dates from China around 7,000 BCE — bowls and ritual objects preserved in waterlogged graves where ordinary wood would have disappeared. The technique spread to Korea, Japan, Vietnam, and Cambodia, and reached extraordinary refinement under successive imperial courts. In the seventeenth and eighteenth centuries, Asian lacquerwork entered Europe through the Dutch and Portuguese trade routes; the cabinet-makers of Versailles adapted what they saw, and the French decorative arts tradition acquired its own lacquer lineage. Pierre Bobot, who taught Eric Stocker in 1974, was a direct heir to that line.
"Lacquer is one of the few materials that improves with age. The first century is its adolescence. Antique pieces from the seventeenth century are not surviving — they are still developing."
How a piece is made
The process varies by tradition, but the essential structure is the same everywhere it is practised. A wooden, bamboo, or sometimes metal substrate is prepared and sealed. Five to ten foundation layers of natural lacquer are applied, each cured for three to seven days in a humidity chamber. The surface is sanded between every coat. Decorative materials — gold leaf, eggshell, mother-of-pearl, mineral pigments, rye straw, beetle wings — are introduced during specific intermediate layers. Ten to twenty more coats are applied over the decoration. Twenty to thirty hours of hand-polishing complete the piece. Total elapsed time: three to six months for a modest piece, longer for ambitious work.
Why it lasts
Cured natural lacquer is one of the most chemically stable materials produced by any traditional craft. It resists water, weak acids, alcohol, and most household substances. It is harder than most wood finishes, more flexible than glass, food-safe once cured. It does not yellow under ordinary indoor conditions. It is sensitive to prolonged direct ultraviolet light — like any natural material — but kept indoors and away from southern windows, it requires no maintenance beyond a soft cloth.
The reason antique lacquer pieces survive in museums across Asia and Europe is simple: nothing else lasts this long. A pair of seventeenth-century Japanese namban chests held in the Louvre are visually almost unchanged from the day they were finished. Eric handled pieces like these during twenty-five years of restoration work at the Mobilier National in Paris.
How to recognise it
A few things distinguish real lacquer from imitations:
- Depth. Genuine lacquer has a luminosity that seems to come from inside the surface, not from a reflective top coat.
- Weight and warmth. The cured material has a particular density and warmth to the touch.
- Time involved. Authentic lacquerware cannot be made quickly. If a piece was produced in days, it is not natural lacquer.
- Visible inlay. Eggshell, gold leaf, or straw inlays should be embedded inside the surface, not sitting on top of it.
- Provenance. Serious lacquer artists sign their work and document the materials used. Stocker Studio pieces carry Eric's signature, year of completion, and a unique number.
Lacquer art today
Authentic lacquer is made in only a handful of workshops worldwide. Most production has shifted to synthetic substitutes; the surviving traditional ateliers are concentrated in Japan, Vietnam, China, and — since Eric arrived in 1998 — Cambodia. Stocker Studio is the only workshop in Cambodia using real natural vegetal lacquer. Our pieces are held in private collections in over thirty countries and in the collection of Mobilier National in Paris.
The Carnets d'Atelier are our workshop journals — reflections on craft, material, and the slow work of making things that endure.
