1. Characteristics of Niello inlay

The most distinctive feature of niello inlay is the contrast between the shine of the silver and the black color of the metal sulfide, which gives depth and three-dimensionality to the decoration and highlights the intricate patterns and designs.
Although the base metal may be something other than silver, it is often used as a decorative technique for silver products to create beautiful contrasts.

Niello can also be used to fill minute grooves, allowing for extremely intricate decoration. In the hands of a skilled craftsman, a wide variety of motifs can be created, including geometric patterns, plant motifs, and human figures.

Niello inlay is often combined with gold plating, and a combination of three colors - silver, black, and gold - is also common.

2. The technique of Niello inlay

The Niello inlay process is a very complicated one that requires the skill and knowledge of a skilled craftsman, and is carried out in the following steps:

Pattern engraving:
The patterns are hand-carved into the silver surface using chisels and carving knives.

Niello's Formula:
Silver, copper, lead, etc. are mixed and reacted with sulfur to produce a black alloy.
The composition of niello has varied over time and region; the Roman writer Pliny the Elder described a lead-free formula, but since then lead-containing formulas have become the norm.

Niello filling:
The engraved grooves are carefully filled with Niello powder.
For fine grooves, precise work is done using thin needles.

Firing:
The silverware filled with niello is heated, causing the niello to melt and set in the grooves.
Firing temperature and time are adjusted depending on the composition of the niello and the shape of the silverware.

Polishing and Finishing:
After firing, the surface of the silverware is polished to remove excess niello and, if necessary, buffed to a high shine.

summary

Niello inlay is a very distinctive decorative technique that gives silverware a black contrast.
Its history dates back to ancient times, and its characteristics vary depending on the era and region.

Items from the Imperial Russian era are relatively new and were made in large quantities, but they were scattered due to chaos such as the revolution and are difficult to find on the market. The alloy parts are prone to peeling due to wear, so there are few that remain in good condition.

It is not easy to find ones in good condition, but as the owner of the store, I personally love this decorative technique, so when I find a good one, I try to purchase it.
