Guys,

FWIW Bill Grumbine seals the inside and outside OF THE END GRAIN part of a
green bowl. States the objective is to slow it down to the rate of the
side grain parts.


Which makes little difference. As you may notice in your firewood stack,
end checks run about 1 1/2" deep before they can no longer draw water from
the interior. Unless you've got someplace on that bowl more than an inch
and a half from being endgrain, and that'd leave out most designs, you might
as well consider the entire to be endgrain for your drying calculations.

As noted, insides don't count, merely adding to the mildew problem if you're
not careful. Fill a bucket half full of sand and spin it vigorously to
bring it up the sides a bit, then plunge your finger in the center. Notice
it closes immediately.

Now heap a cone up in the center and plunge your finger in. Not only does
the hole stay, it may cause a further avalanche. Pretty good analogy for
what the incredible average bowl does.
