The Process of Laser Engraving on Timber

Each Thomas Anne case lid carries a laser-engraved coin imagery — the denomination design cut directly into the finished surface. The laser removes the painted finish in precise detail, exposing the natural timber grain beneath. What remains is not ink, not foil, not a label — but the wood itself, speaking through the opening the laser has made. Depending on the piece of timber, that exposed wood may carry warm amber tones, or lean into the pink and red spectrum natural to mahogany heartwood.

The process uses a focused beam calibrated to the depth of the finish layer. Where the beam passes, the walnut-toned paint is vaporised and the raw timber grain is revealed — lighter, warmer, and textured in a way the painted surface is not. The contrast between the dark finish and the pale exposed timber is what creates the visible imagery.

No two cases are identical. The grain of each piece of timber runs its own course — and where the engraving intersects with that grain, the result is entirely its own. This is not a defect. It is the nature of working with a living material.

Paint Ablation — Revealing What Was Always There

The engraving technique used on every Thomas Anne case has a precise name: paint ablation. The laser does not burn into bare timber. It burns through the painted finish first — vaporising the coating in exact detail — to expose the raw mahogany surface beneath. What you see in the engraving is not a mark added to the case. It is the case itself, uncovered.

The process leaves a fine carbon residue — the remnants of the vaporised paint — which sits in and around the engraved channels after the laser has passed. Each case is then wiped clean by hand. As the residue is removed, the design emerges for the first time: the pale, warm grain of the mahogany appearing through the opening the laser has made in the dark finish. This moment — the first reveal after wiping — is different every time. The timber decides what it looks like.

Because the technique removes rather than adds, the result has a depth and subtlety that printed or applied finishes cannot replicate. The engraving sits slightly below the surrounding surface. It catches light at an angle. It has texture. Run your finger across the lid and you will feel the difference between the painted surface and the exposed timber within the design — a physical relief that confirms the imagery was made, not placed.

Paint ablation on stained hardwood is an uncommon technique in production work. Most laser-engraved timber is bare wood to begin with — the laser simply darkens the surface. The Thomas Anne approach inverts this: the finish is the canvas, the laser removes it selectively, and the natural timber beneath becomes the image. The result is a two-tone surface created entirely by the material itself — no inks, no dyes, no additional colouring of any kind.

Why Lighting Changes Everything

The engraving is not static. Its appearance changes entirely depending on the light source, angle, and distance from which it is viewed. This is not a limitation — it is the quality that makes it alive.

Warm, directional light — a desk lamp, a candle, afternoon sun at an angle — is the engraving's natural environment. When light falls across the surface rather than directly onto it, it catches the edges of the engraved channels and casts fine shadow into the recesses. The depth of the cut becomes visible. The grain of the timber glows. The imagery sharpens into relief.

Cool, flat, or overhead light — a phone camera flash, fluorescent office light, or direct midday sun — flattens the surface. The contrast between the finish and the exposed timber is reduced. The engraving appears fainter, the grain less pronounced. The case looks like a lesser version of itself.

This is why photographs taken under the wrong light can appear to underrepresent the engraving. The same case, under warm directional light, will look entirely different — and significantly more beautiful.

The Pink and Red Tones in the Grain

Mahogany is not a neutral timber. Beneath the deep walnut finish, its natural heartwood carries warm undertones — and in certain pieces, these undertones lean into the pink and red spectrum. When the laser exposes the timber through the finish, it is this natural colouration that comes to the surface.

The degree to which these tones appear depends entirely on the individual piece of timber. Some pieces carry almost no red — revealing a pale, honey-coloured grain. Others carry a distinct warmth that reads as rose or terracotta in certain lights. Both are within the natural range of the species. Neither is a fault. Both are the timber telling you what it is made of.

Under warm light, these tones deepen and enrich — the reddish grain glows amber alongside the dark painted surface, and the contrast between the two is striking. Under cool or neutral light, the tones appear closer to pale brown and the red character is less pronounced.

We have chosen not to stain or seal the exposed timber after engraving. Doing so would obscure the natural character of the material and reduce the visual depth of the piece. The colour you see is the colour of the wood — unaltered, honest, and particular to your case.

Grain, Character, and Natural Variation

The mahogany used in Thomas Anne cases is a timber of warm character. Its grain runs in long, relatively straight lines with occasional figuring, and its natural colour sits in the range of pale amber to soft honey. When the laser exposes it through the finish, this warmth emerges against the deep walnut of the painted surface.

Because grain is never uniform, the engraving interacts differently with each piece of timber. Where the grain runs parallel to a fine engraved line, the cut is clean and the contrast sharp. Where the grain crosses the engraving at an angle, the texture of the wood becomes part of the image — softening edges, adding dimension, making the piece uniquely its own.

The depth of the paint layer also influences the result. A thicker application of finish means the laser must travel deeper before reaching bare timber, which can affect the sharpness of fine detail. A thinner application produces crisper lines and higher contrast. Both are within the Thomas Anne standard — but they produce slightly different aesthetics, and this is intentional. Each case is individual.

Why Your Case Will Look Different From Another

If you place two Thomas Anne cases side by side, you will notice differences in the engraving. The imagery is identical — the same denomination design, cut to the same depth — but the result will not be a perfect copy. The grain of the timber runs its own course. The finish may sit at a slightly different thickness. The laser passes at the same calibration, but the material it meets is never the same twice.

This is the nature of handcrafted objects made from natural materials. It is also the quality that makes your case yours. The engraving on your lid exists nowhere else in exactly that form. It is a record of the specific piece of timber from which your case was made.

We do not consider this variation a flaw. We consider it the mark of a material object — one that carries the evidence of its own making.
