I wonder... if the beads have shattered due to (internal) heat stress,
would it be safe to assume that they've also lost all of their RF
absorbtive properties as well?  Not because they're in pieces, but
because of the excessive heating?

Anyone with real knowledge (as opposed to sheer conjecture) on this 
subject care to comment.

And if so, are there larger (heavier duty) beads available which might
be better choices than those many of us now use?
