Secretion 4 — Alchemy: How Four Components Become Niello

Silver sulfide, copper, lead, sulfur — and a 2,000 degree gas flame. How SevChern creates the black line from four components that won't come off.
At SevChern, every line is cut by hand — with a graver, the tool that has remained unchanged for 300 years. Why a laser cannot replace it.
Before the silver meets the graver, it has felt the hand of an artist — like Olga Petrova at SevChermet, who crafts every ornament from paper.
Before the niello is applied, SevChern melts pure 999.9 silver in an induction furnace at 1080 °C — with a slight surplus for the benefit of each buyer.
