Dick Johnson submitted this entry from his Encyclopedia of Coin and Medal Terminology. Thanks. It's a rare term often overlooked by collectors. -Editor
Niello. A design entirely of engraved lines. Niello medals have a flat background or field which is engraved (CISELE). They can be struck from
dies which have very fine lines or niello medals can be hand engraved (one at a time). Niello dies must be handled with extreme care, since they are entirely of fine raised lines
they are susceptible to damage.
Early niello objects, including medals, had the incised lines filled with a material composed of copper, lead and sulphur of borax – a form of black FILL-IN which was fired and
polished. Such objects lacked modulated relief as all niello is biplanar – of two planes – incised lines in a flat surface with a fill-in of the incised lines.
The modern photoengraving process can produce medals of this type (PHOTOETCHED) from a black-and-white drawing – and the Paris Mint has issued numerous medals in this
cartoon-like style – however the process is not widely used elsewhere in modern times. True niello has the black fill-in of the sulphur/borax composition. An imitation niello
would be made in modern times with black enamel or crayon fill-in. A bas-relief model is not required for a niello medal, only a drawing.
CLASS 07.8
