Default Re: Tarnished Silver as a Crystal Radio Detector

Hi OM Graham,

The razor blade I used was a 'Gillette Platinum' (not blue).

The small embossed resin-filled artefact is made of silver foil and had been lying in the loft for years.

I suppose a well tarnished EPNS piece would work just as well.

Have fun!
