[meteorite-list] Meteorite casting.

[spocke at poczta.onet.pl]

Hi,
When you find a new meteorite you suppose to send a sample to analysis. This means that you will need to cut it and you will loose its natural beautiful shape. Can you do a casting of the meteorite before you will cut it? What kind of materials should you use not to affect a meteorite's chemical components? Is it recommended or not to do a meteorite cast before a sample analysis? Does anybody have any experience in casting a meteorite?
Best regards,
Marcin.
