Lac Turning, In Practice — How to Use Friction-Lac Sticks

The whole finish happens at the lathe, in about the time it takes to read this page. A stick of solid colored lac, pressed to the spinning work. A dried leaf to spread and burnish it. A dab of oil at the end. That's the entire kit, and the entire schedule — no brush, no rag, no waiting overnight for a film to cure.

But "simple" isn't the same as "obvious." The Channapatna turners who taught the world lac turning learned it hand to hand, by feel, and the feel is the part a printed page has always struggled to carry. What follows is what we've learned at our own lathes with the First Edition sticks, folded together with what our partners on the ground in India brought back from the lac-turnery workshops of Channapatna this summer. It comes down to three things: pressure, the leaf, and restraint with the oil.

Before you touch the stick

Start with bare wood, sanded smooth. In the lac-turnery workshops of Channapatna nothing goes on the seasoned wood before the color — no sealer, no wash, no oil. The lac bonds to the wood itself, so give it wood to bond to.

Don't overthink lathe speed. The Channapatna workshops run several lathes off one shared motor, one speed, all day — the same speed for laying color and for burnishing. The technique lives in your hands, not in the speed dial.

And prepare your leaf before you need it: soak it in water to rehydrate — warm water works well — then let it dry again for several hours. A brittle leaf sheds, and you don't want small pieces of leaf falling off into your finish. This mirrors the artisans' own practice — they soak their leaves for ten minutes at the end of a day's work, and by morning the leaf is dry, supple, and ready. A leaf that's gone crunchy-crisp will want that soak-and-dry again; it comes right back. Fold it over once or twice when you use it, so you're working with a thicker burnishing pad.

Laying down the color

Press the stick to the spinning work fairly hard at first. You're not painting — you're generating heat, and it takes real pressure to bring the contact point up to where the lac melts and starts to transfer.

Then feel for the moment it grabs — the stick suddenly biting and flowing instead of skating. That's your signal to back off the pressure. Lighter pressure from there gives the best coverage and spread. Keep leaning on it hard and you'll start scraping off the very shellac you just applied.

When it grabs, back off.

Don't worry if the color looks uneven or streaky straight off the stick. The stick's job is to deliver material. Evenness comes from the next step.

Twenty seconds of laying down blue at our own lathe, real time: press until it grabs, ease off, and let the band build.

The burnish

Here's the thing we didn't fully appreciate until we watched the artisans work: the leaf, not the stick, is where the finish comes from. The stick applies the color; the leaf spreads it even and brings up the shine.

Fold your leaf, press it to the spinning work, and make one smooth pass across — steady, moderate pressure, traveling the length of the colored area. Done right, that one pass is all you need.

The failure mode is the same as with the stick: too much pressure remelts the finish and strips it right back off. If your burnish is undoing your color instead of polishing it, you're pressing too hard. Lighten up, keep moving, let the heat do the work.

The oil — less than you think

A final polish with coconut oil brings the surface to a true mirror. (Peanut oil works as well.) Two rules, and the first one is the whole trick:

Use the tiniest dab. Seriously — the smallest amount you can pick up. More oil does not mean more shine; it means a surface you can't work.

Only after the burnish. Oil kills friction, and friction is the engine of this whole technique. Introduce oil before the color has been spread and you likely won't be able to generate enough grip to move it at all. Color first, burnish second, oil last.

A practice we've settled into at our bench: keep one side of the leaf for oil and the other side lac-only. The leaf doesn't absorb the oil so much as carry it — the artisans manage the same thing with a fingertip while they burnish, but the two-sided leaf gets you there with less to juggle.

The leaf earns its keep

We tried a lot of burnishing materials before these leaves — and the leaf won. It's remarkably resilient under this work: one section lasts a very long time, and when it eventually stiffens up, a soak and a few hours' dry restores it. In Channapatna a well-kept leaf serves for months. Treat yours the same way and the one in your set will see you through many turnings.

Field notes from Tyler David

Our friend Tyler David has been practicing lac turning at his own lathe longer than almost anyone in the States — he presented the technique at the 2026 AAW Symposium, and he even makes his own sticks from button lac. He sent us a generous set of tips from his bench, and they're too good not to pass along:

• Start on a spindle. The sticks apply easiest to a straight section, 1–3" in diameter, turning around 1500–2000 rpm. Get the hang of it there before you attempt beads, coves, and larger diameters.
• Colors mix. Apply a light coat of the darker color first, then a light coat of the second color over it. And there's a happy medium to how much you lay down — too little and coverage suffers; too much and it goes globby, too thick to ever reach the mirror.
• Detail with the skew. The point of a skew chisel cuts the color cleanly and leaves crisp edges — a fine way to put small details into a finished surface.
• A topcoat, if you want one. For even more shine, Tyler sands the color lightly with 400-grit, then brushes on spar urethane with the piece turning slowly in reverse on the lathe. He'll also sometimes apply multiple colors without burnishing and go straight to the urethane — a cool, abstract look, and a reminder that these sticks reward experiment.
• And his last tip is the honest one: this method takes practice. Keep experimenting, and start small.

On the bench

• Friction-Lac Sticks — First Edition Set — three sticks, hand-numbered, one of 30, with a voivoi burnishing leaf from the artisans of Rise Beyond the Reef.

That's lac turning: touch color to spinning wood, spread it with a leaf, finish with the smallest dab of oil there is.
