Hi Johnny Blue,
In a case where magnification is limited or not possible and with tiny pieces, I would take a piece of Scotch Tape (or similar) and encase one of those pieces in the tape. This would be done with two long ears of tape left on either side of the sample (the tape is folded over the sample in such a way that neither of the 'ears' are sticky. With this done some ability to hold the sample is possible. Then take a smallish hammer and hit the sample. If the sample flattens then it is a malleable metal, if the sample shatters It Ain't Gold! If it flattens then I would remove from the tape and heat the piece with a torch to see if it melts easily. If it melts easy, forms a shiny silver puddle then it likely is lead. The best of success with your Quest!!...........................63bkpkr
