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!
73,
Nandu.
