Sometimes patience is your only answer. I've had driftwood that has sunk after an hour of boiling, others that have taken 6 weeks, and one piece I remember, never did sink after 2 months of being weighted down in a plastic bin.

Have you tried putting it in the dishwasher yet and running it through a cycle of hot water?

I mentioned that to my wife one time, and she said if you wash that in the dishwasher, we're buying a new dishwasher. I never did wash it.
