Oops, didn't realize the whole soaking/tanin thing was already dealt with on your other thread. As for baking, a friend of mine who keeps reptiles told me 30 minutes at 300 degrees. KEEP AN EYE ON IT THROUGHOUT THE PROCESS. Size of the piece and dryness vary the safe time/temp and makes it absolutely necessary that you stay near the stove the entire time. Double lining with aluminum foil is also a good idea in case any sap or other goodies leak out or you will have a hell of a smoky, sticky mess on your hands.
Also, although this should kill any parasites, the wood is not considered 'sterilized' unless it is boiled - I have no clue why. I would imagine high temps are high temps.
