Giant Meteorite Discovered in China

Here is a link to some other meteorites for some more info.


I have always like the smooth iron ones.

Oh, about the lead type, maybe it was an alloy, the oven didn't have to be over 700ºF for me to pour (that was it's MAX). I would begin to clean the oven at 600º when it was largely liquid, (dropping in some canister of blue something wrapped in a lead casing), it smoked like hell for about 20 minutes, (one leaves the room), and gets the dirt to float on top so I can skim it off and throw on the floor.

Pure lead as an element has a melting point of about 622º F. I know I can melt thin solder with a match. Only tin, and 'phosphorus' have lower metal melting points than lead, unless you count mercury.

I wouldn't be surprised if the lead I melted was a tin alloy lead, but mostly lead because it was very heavy and tin isn't. I'd wager to guess that a cubic foot (easily one of the 'dump trucks') I had to empty weighed over 700 pounds. Water is about 62 pounds per cubic foot. I'm sure you can look up tin.

Lead is beautiful because it always holds it's gleaming silvery sheen. I used to paint some small ingots with gold metallic paint to tell my friends (we were kids OK) that I have real gold bars. Of course gold is heavier, but kids really didn't know by how much. A tiny palm sized ingot would be a sizable weight, like 5-8 pounds. OK, I'm done hijacking this thread, sorry.
