In the third secret, you saw how a master cuts V-shaped grooves out of silver with a graver — clean, deep, mirrored lines. Now comes the most dramatic moment: the black must go in. Not as lacquer, not as ink. As a second metal that binds with the first.
The fourth secret is called Alchemy
Niello is not a print. It is its own metallurgical alloy — and its exact mixing ratio has been the secret of the Veliky Ustyug masters for almost 350 years. What is publicly known: sulfides of silver, copper, and lead, plus sulfur. What is not public: the exact ratio of these four components to each other.
“The ratio of the individual components of the niello mass was the secret of the masters of the Veliky Ustyug craft," the factory states in its official materials. “It remains so to this day." It is not written down, not passed on except to the next masters in the same factory. You can find the basic components on the internet — but trying to replicate it at home won't work, because you also need to know temperatures and time intervals.
Step one — the silver must be naked
Before the niello can be applied, the silver surface must be absolutely grease-free. Any trace of skin oil, polishing wax, or dust would interfere with the fusion. The workpiece is boiled in caustic soda, then cleaned with a roller brush and carefully dried.
Only then is the piece clamped in a special holder made of clay — because what comes next is hot. So hot that no human hand could hold the piece directly.
Step two — the black powder is applied
The niello mass, which looks like a dark gray stone, is ground into fine powder, mixed with water to form a paste, and applied evenly to the engraved surface. The powder covers the V-grooves — everything that is to be inlaid. Precisely and calmly, without air bubbles.
Step three — the gas flame
Now the dramatic moment: The workpiece is guided over a gas flame. The flame temperature is approximately 2,000 degrees Celsius. In this heat, the niello powder melts. It becomes liquid.
What comes next is the most delicate movement in the entire process: For the molten niello to fill the depressions of the engraving without bubbles and evenly, the master must constantly move the workpiece. He tilts it slightly, turns it, inclines it. Niello is heavy and sluggish — but it follows gravity. The movement guides it into every single V-groove that the graver has cut.
During this process, the niello does not just connect superficially with the silver. A molecular bond is created — the sulfides diffuse minimally into the silver lattice and form a true alloy transition zone. This is the point at which two materials become one piece.
Step four — the first acid bath
After firing, the piece goes into a sulfuric acid solution. This dissolves excess residues from the clay holder, powder residues, and all oxide layers that formed during firing. Then, a roller brush, repeated rinsing, repeated drying.
What lies before the master now does not yet look like a finished niello piece: The surface is a solid black layer. The pattern is inside — but it is not yet visible.
Step five — making it visible
Only now does the workpiece go to the grinding and polishing workshop. On rotating abrasive bodies, the excess niello layer above the silver is removed — piece by piece, in several stages. With each stage, the silver becomes brighter. With each stage, the pattern becomes clearer.
In the end, the eye sees what the V-grooves promised two weeks ago: A black niello drawing, inlaid like a tattoo in the mirrored silver. It cannot flake off. It cannot rub off. It is part of the metal.
Who makes this work
One of the niello masters at SevChern has been working there for eight years — he has reached the fourth degree, belongs to a family whose ancestors already made niello in Veliky Ustyug. When asked what the most beautiful part of his work is, he says: "This is the only work of its kind in Russia. Russian North, tradition, generations who have worked here — somehow you want to be part of it too. To touch something great, so to speak."
“On the street, I meet people wearing our pieces. There's a joy — a kind of pride. But for the factory, the greatest pride is: the people who work here. They put love, knowledge, and talent into the production — so that the factory can continue to surprise the world with true works of folk art. Works that are rightly a national heritage of Russia."
What this means for you
When you pick up a SevChern piece with niello, you can test it: Run your fingernail over the black line. You won't feel any transition. The line is not applied — it lies in the silver. Try to scratch it. You can. But then you'll also scratch the silver. Both belong together.
This is the guarantee that no certificate can express: Niello at SevChern is a fusion of metals. It cannot cease.
In the next secret
We're not done yet with the finished niello piece. What comes next is the refinement: galvanic gilding with 990 gold, the final mirror finish, the triple contrast of gold, polished silver, and matte niello. Who does it, since when, and why the grinding motion must be circular, that is Secret No. 5 — the completion.
