[meteorite-list] New Topic - Can you ID - Fusion Crust

[Thunder Stone]

List:
 
I was wondering if anyone can ID a meteorite type solely on the fusion crust; like drinking different cokes or holding agate nodules and identifying the ones that are geodes.
 
Imagine a number of half-cut meteorites on a table (cut-face down); could you ID the types of meteorite, and how would you do it? Only looking at the fusion crust.
