What does galvanoplastic mean?
Galvanoplastic is a technical adjective describing a method in which metal is deposited onto a form by electrolysis. The deposit builds up as a continuous layer and can reproduce the shape of the original object or form. Galvanoplastic methods are especially associated with electrotyping, the traditional production of printing plates, and with electroforming, in which a usable metal shell is made around a removable form. The term is uncommon outside specialist writing in metallurgy, manufacturing, and conservation. It is also occasionally used more broadly to describe electrolytic metal coatings. Although “galvanic” may sound similar, it concerns chemical electricity more generally, whereas “galvanoplastic” identifies a particular metal-forming application of electrolysis. The word is worth knowing because it names a distinctive combination of chemistry, electricity, precision, and metalworking.
adjectiveOf or relating to galvanoplasty, especially the electrolytic deposition of metal on a form or object to create a shaped or reproduced metal layer.
- Relating to the electrolytic deposition of metal on a form or object, especially for making plates, shells, or exact reproductions.
"The workshop used a galvanoplastic process to reproduce the sculpture in copper."
"The workshop used a galvanoplastic process to reproduce the sculpture in copper."
"Restorers applied a galvanoplastic coating to the damaged handle before finishing it by hand."
A metal shell can be grown around a form and then slipped away—a remarkable way to reproduce an object in solid metal.

Where does galvanoplastic come from?
Galvanoplastic was formed in English during the 19th century from “galvano-,” associated with the Italian scientist Luigi Galvani, and “-plastic,” derived from Greek plastikos, meaning moulded or formed. The combination refers to shaping or depositing metal through an electrolytic process. Its relatives galvanic, galvanism, galvanize, and galvanometer likewise derive from Galvani's name.
How galvanoplastic is actually used
This is a rare, formal technical term, used chiefly in metallurgy, electrotyping, electroforming, and the conservation of metal objects.
Easily confused with galvanoplastic
Galvanic refers broadly to electricity produced by chemical action or to effects associated with such electricity, whereas galvanoplastic specifically concerns the electrolytic deposition of metal.
