[meteorite-list] Irons DON'T form Fusion Crust's - yes they DO

[Mark]

Hi List

It occurs to me that many "silicated" irons exist. So, if it walks like a 
duck and looks like a duck....

I defined glass in a previous post specifically as
that which is formed from fuseing/melting silicates.
Which is closest to your thrid definition of "glassy".
This isn't a discussion of commercial applications of
glass or philosophical ones.  You missed the point of
this whole arguement that technical literature defines
fusion crust as containing glass -- the amorphous
state of silicates.  There is no manipulation of the
terms by me. I quoted directly from the published
definitions. I used your website in research  btw.
