AW: [meteorite-list] Etching Neumann lines

[Martin Altmann]

No, over-etching doesn't help.

Btw. Neumann lines are also quite common in octahedrites,
I know a wizard, who brings them out in almost all irons and even in
mesosiderites..at least if there are Neumann lines inherent.
But his recipes and elixirs are a secret.

Betreff: [meteorite-list] Etching Neumann lines


Hi again folks,

It has been a while, but,

correct me if I am wrong,

I remember cutting up a few Henbury Irons and polishing and etching them, a 
few that I left in my etchant for way to long ended up looking very much 
like these pics.

Is an "over etch" the standard way to get these Neumann lines to become 
visible?

Cheers, Kevin Forbes, VK3UKF.
