That sounds good but there are so many degrees of crust. Thick primary,
double thick primary, primary ranging into secondary with metallic splatters
and thin secondary that ranges suddenly into a zero crust pristine matrix.
Fine misty crust mixed with matrtix and metal that that fogs over the piece
next to it during any stage of ablation. Hard to codify all the combinations
that I've seen and I've seen so few. I can only imagine the limitless
variations.
