[GreenKeys] Way OT: fun with molten metal

[hwhall at compuserve.com]

Once was 'way into mineral & crystal collecting. Some smelter started selling crystallized Bismuth samples and later it turned into a deliberate product instead of just an accident. The crystals I have tend to be cubic and hoppered (like salt will do) and have rainbow effects on the surfaces. Interesting things to look at!

   If you want to have fun with a little more safety, try using bismuth metal & it's alloys.

Melt temps are BELOW water boiling point , 212F.

Really handy stuff.

     Quite amazing! to actually produce a metal representation of the? ant  city!
 ?
 A note of warning though ...if there is a lot of moisture in the?  ground?? the aluminum will?literally? explode back up?  towards? you with the moist? earth.? We had a great?  foundry? area in High School and eve once in a while? someone?  would? slop molten aluminum?? on the most? California  concrete resulting? in exploding floor material!

    Hey, here is an unusual thing to do:? pour molten metal into an ant    hill, and dig up a mold of the colony.? Yeah, it kills all the ants, of    course, but shows just how deep and wide those lil buggers dig.
   

   Personally, I leave ants alone if they are far enough away from the    house.? If they are near the house or getting inside, then it is time for    them to go.? Amdro is my fav chem to nuke the nest, but maybe next time    it's time to fire up the kiln!
