I'm sorry for getting to this forum so late, DO NOT THROW AWAY THAT BLOB.. I've recently found 10 of those here in Kansas, my first thought was aluminum aswell but my detector went ape !!!!. Definitely not aluminum otherwise it would've said its aluminum. It came up as jewelry/Silver. I've read alot of posts tonight and people are revolting this stuff.. STOOOOP. Dont lick it, dont eat it, and dont burn it! I took every one of my blobs to a spectrometer and they all pretty much weigh the same 5-7 grams. My Blobs are Identical to yours and everyone else's I've seen online. This is what our stuff is composed of:
Ag: Silver
Au:gold
Ni: Nickel
Cu: copper
Zn: zinc
Pb: lead
Cd: cadmium (More poisonous than cyanide)
Fe: iron
I'm almost guaranteeing you that your blob is also in that order from silver being the most of its content and iron being the least. I've called a lot of people here in Kansas for the last few weeks and they are stumped. Nobody knows what this is and everyone says its man made and melted junk.. It's literally a chunk of silver and almost every other metal including gold. It's not junk. The bad thing is the cadmium. There is no safe way to separate the cadmium from any of the metals you want to keep like gold or silver in your blob. Touching it is safe but licking it or it somehow getting into a wound or you breath it in while its burning then your screwed my friend. I thought this was just a weird Kansas thing but I've seen people asking about this from Scotland and their silver blob looks just like ours. Please spread this message. I dont know any other way to find out what this is or where it came from, perhaps carbon dating is our only option. I can see where this Could be a meteorite but its non magnetic despite iron and nickel and such. However metals in their RAW form are not powerful enough to be magnetic. So could this be a freak occurence? Or riches waiting for a name to be put on this stuff. It's not aluminum.
