What is etching in jewellery making?

Definition
Etching is the process of using acid to selectively eat into the surface of metal, creating recessed patterns, textures or designs. The jeweller coats the metal with an acid-resistant substance called a resist, draws or scratches the design through the resist to expose the metal, and then immerses the piece in acid, which attacks only the exposed areas. The result is a slightly soft, organic quality distinct from the clean lines of hand engraving, and it can cover large areas of metal with repeated patterns more efficiently than cutting each line by hand.
Frequently asked questions
- What metals can be etched?
- Copper, brass and silver are the most commonly etched metals in jewellery making, as they respond well to standard etching acids like ferric chloride. Gold requires stronger acids and specialist handling, so it is less commonly etched at a bench level.
- What is the difference between etching and engraving on metal?
- Engraving removes metal mechanically with a sharp tool, producing crisp, precise lines. Etching removes metal chemically with acid, which gives a slightly softer, more irregular edge and can be used to create fine overall textures and tone across a surface.
- Is etching used in modern jewellery?
- Yes, both traditional acid etching and photochemical etching, which uses light-sensitive resists to transfer very detailed imagery, are used by contemporary jewellers for everything from delicate surface textures to elaborate pictorial work.
