(in article ): ncidentally, let me introduce an entrancing new time-wasting site, http://20q.net, which will help explain why I'm running so far behind on Usenet. I actually got behind when I added the StumbleUpon extension to Firefox and this site added to my woes. I even went to http://www.20q.com and bought a couple of the little hand-held version for our god-kids (and one for myself, naturally). Mary "try 'diagonal cutters (dykes)' at 20q.net" Heh, My older daughter has a little electronic gadget that plays 20 Questions incredibly well for a device with the processing capability of an Apollo Guidance Computer. The site guessed my cell phone within 16 questions, but I had the last laugh. I fooled it with a certain item my wife likes - after 27 questions it gave up with the final guess, "Get your mind out of the gutter - but I am guessing it has something to do with sex!" ;-) -- Herb Schaltegger, GPG Key ID: BBF6FC1C "They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety." - Benjamin Franklin, 1759 http://www.angryherb.net |

Have a look at http://www.goodearthgraphics.com/virtcave/pearls/madperls.jpg. I've got a couple of these and they're not particularly fragile. They're certainly not brittle. They are really cool, though. Try to dent one and tell me what happens. These two photos appear to show two different spheres, based on the differing degree of oblatness: http://www.ufoarea.com/pictures/spheroids.jpg http://www.ufoarea.com/pictures/spheroids2.jpg (unless somebody's been fiddling with the pictures to get the second one to be more spherical, although you note that the hole in the center of the dent appears to be off-center in the opposite direction in the second photo.) Each has a dent or hole in it...I suspect there is another hole 180 degrees opposite of it, as this is where the string goes through them when they are made into a necklace or bracelet. I think these are corroded brass or bronze beads of some sort. The corrosion visible on them has a whitish or greenish hue, which suggests copper is a key component of their chemical makeup. Cave pearls require a lot of free water but sun disks (pyrite suns) don't and they look about as man-made as they can be. I was sure they were cast, not grown naturally. Those are neat; I don't have one, but I've seen them. You should see my "Fossil Chesire Cat" sometime. I was out rockhounding, and came across a dark gray rock with a calcite intrusion in it that makes a white toothy grin on one side. Incidentally, let me introduce an entrancing new time-wasting site, http://20q.net, Yeah, somebody else mentioned that site here a few weeks back; the thing is scary, isn't it? Pat |
