Hello listees,
...bit of an obvious observation but I noticed on my Allende individual I
got today (Thanks, Christian!) that the fusion crust is peppered with tiny
holes whereas my Millbillillie crust is a solid (unperforated) glassy coat.
I guess I know why this is ie exgassing during atmospheric entering, butI
was just curious as to what EXACTLY what gases were escaping - water vapour
or whatever.
And therefore the assumption that Millbillillie has far less 'free' gases in
the matrix maybe drawn.
Any comments?

very best!
