A lacquer wall panel is not painted. It is grown — built up over months, layer by patient layer, until the surface carries a depth that cannot be applied in a single pass. What you see hanging on a wall is the visible outcome of an invisible discipline. Here is how each panel actually comes into being, from tree to finished piece.
The substrate
Every lacquer panel begins as a stable, lightweight wood support. We use hevea — the rubber tree, milled in Siem Reap. It is uniform in grain, predictable in its movement with humidity, and bonds well with natural lacquer. The wood is cut, planed, and inspected for splits before any sap touches it. A bad substrate will betray itself thirty layers later, so the first hour of work decides the next three months.
The lacquer itself
The material is sap from Gluta laccifera, harvested by tappers in the forests of Kampong Thom province, Cambodia. Fresh from the tree it is highly toxic — caustic to bare skin until it has cured. It must be filtered, gently heated, and aged before it can be brushed onto wood. Cinnabar, ochre, lapis, charcoal, or other mineral pigments are stirred into specific batches; other batches are kept clear, for use over gold, eggshell, or rye straw inlays. None of this is industrial. The same six families have prepared lacquer this way for generations.
Foundation layers
The first five to ten coats are applied with broad brushes — traditionally made from human hair for its fineness — in long, even strokes that follow the grain. Each coat is thin: too thick and it wrinkles, too thin and it starves the surface. After every coat, the panel is moved into a humidity chamber kept between seventy-five and eighty-five percent — because natural lacquer cures through oxidative polymerization, and that reaction needs moisture, not air. Each coat takes three to seven days to harden fully. Between coats, the surface is hand-sanded with progressively finer abrasives to receive the next layer.
"People imagine the lacquer is painted on. It is not. It is built — and the part you see is only the last layer of an architecture that goes all the way down to the wood."
Decoration
The decorative phase is where the panel becomes itself. Depending on the design, this stage may include:
- 24-karat gold leaf, hand-laid sheet by sheet onto a prepared bole or wet lacquer ground.
- Eggshell mosaic — fragments crushed by hand and pressed one at a time into the tacky surface with bamboo styluses.
- Copper leaf, sometimes oxidised with botanical imprints for natural patina.
- Rye straw marquetry, an old French technique we revived in Cambodia — split straw arranged in geometric patterns.
- Mineral pigments mixed directly into specific layers for embedded colour rather than surface paint.
This stage is the slowest. A single panel of eggshell mosaic can absorb several days of placement, and a multi-panel gold-leaf installation can take a master artisan weeks of full-time work. Nothing here is reversible without starting over.
Burial layers
Once decoration is complete, ten to twenty more coats of clear lacquer are applied over the inlay. This is the step most people do not see in photographs but it is what gives lacquer its signature depth. The decorative materials become embedded inside the surface, not sitting on top of it. When light enters the finished panel, it travels through several cured layers before returning to the eye, carrying with it the warmth of every layer it passed through.
Polishing
The final twenty to thirty hours are spent in hand-polishing. The panel is rubbed with charcoal powder, then with progressively finer agents, and finished with bare hands and oil. This is not a buffing operation; it is a transformation. The surface goes from matte and dull to mirror-smooth and luminous. The temperature of the artisan's hand matters. The pressure of the stroke matters. The room's humidity matters. Most pieces are taken to the verge of completion, then set aside for a day, then finished — because polished lacquer continues to settle for hours after the cloth is put down.
Eric's eye
Every panel that leaves the workshop is inspected, twice, by Eric Stocker before it is signed. Not all panels pass. Those that do not are stripped and begun again — sometimes after months of work — because a single layer of buried hesitation will telegraph itself to the finished surface. This is the rule Pierre Bobot taught in 1974 and it has not changed.
How long, in total
A standard wall panel — twenty to thirty layers, modest decoration — takes three to four months. A complex piece with eggshell mosaic, gold leaf, and burial layers can run six months. A monumental multi-panel installation can take a year. Lacquer cure time cannot be accelerated by any modern means. Every project we accept plans around it.
What this means for the buyer
A lacquer wall panel made this way is not decoration in the disposable sense. The seventeenth-century lacquer cabinets that Eric restored at the Mobilier National in Paris are still in daily use; antique pieces from the same period are present in museums on three continents. With basic care — soft dry cloth, away from prolonged direct sunlight, indoor only — a Stocker Studio panel will outlast the building it hangs in.
