Well, we don't know what background this guy has... perhaps he is more comfortable working with metal or started with some related skills. Also, he worked with metal clay, took that material at 'face value' as a credible stand in for traditional precious metal use... and does not seem to know that polishing and plating it is not a straightforward proposition, so that does sound like a gifted beginner's tale.
I wonder how long before precious metal clay will make its way in the beaders' forum here.
Btw. that recipe sounds awesome!
