A fully tarnished, shiny black silver artefact was tried out as a detector in place of the germanium transistor in my series-tuned, shunt-fed crystal radio.
Fortunately the presence of an untarnished spot facilitated the metal to metal connection.
A length of pencil 'lead' was used to probe the tarnished portion to locate the 'sweet spot'.
