[meteorite-list] Photos of a meteorite?

[Göran Axelsson]

I don't think it is necessary to dump a meteorite in the acid etch. I 
have used a toothbrush to apply a small amount of acid to the surface of 
a meteorite to get a partial etch. The good thing is that you don't need 
much acid and you could watch the pattern appear and stop when you feel 
it's enough.
Any acid proof brush should do, I just happened to have a tothbrush at hand.

... no, I didn't use it on my teeth later.

   :-D

Just for comparison, and as an example, please look at all those beautiful Henburys with a natural reddish-brownish patina left to them - aren´t these far, far more pretty than all those others which at some point after having been picked up from  the desert had hit some fate of preparation and "face-lifting"? Or is it just me who thinks this way?
