When you use the pine branch as an anvil, burning and brushing the end
grain to bring out the growth rings, this is what you will get on the
interior of your pot. This is a rather uneven example. With practice you
get a wave or fish scale effect. I often decorate the lid with the anvil
as well to mirror the interior of the pot.
I make my bats in the same way as paddles, with the burner treatment.
Then the bottoms of everything made on them reflects the nice wood
figuring. I make the bats out of cedar because pine is so pricey. Too
bad, because pine often has nicer figuring.
