Hi Charlie, Roberto, and R.S...
Thanks for the clarification. I was afraid I had forgotten some important technical term from the few geology courses I had long ago. Apparently "hardstone" means "hard stone". Ok... Poking around on the web, I see that in archaeological contexts it is also sometimes used generically in reference to the igneous/metamorphic rock from which hand axes, celts, etc. are manufactured.
R.S., I have a reply to you regarding cameras/optics, but this involves two photos, and at the moment my web site's server is hosed up, so it'll have to wait.
Regards, Alan
