Cork bark and malaysian driftwood prep

[Transcendental topiary]

I took a trip and phoned just about every aquarium, herp shop and pet store in my area looking for suitable wood for a high humidity vivarium. Found some malaysian driftwood for a great price from a herp breeder... might go buy more it was so well priced and a cork bark flat and a couple rounds. I know if your keeping an animal in your viv you should sterilize it before adding it. I assume its a good idea to do the same even without animals in the habitat. I'd hate to bring in something and have it destroy all the hard work im going to be putting into this viv. Any suggestions how to go about this? I went to a couple second hand shops looking for a large pot to boil them all in and no luck. I read that boiling them will ruin whatever pot you're using so im going to have to go out and find a suitable pot i guess. I also read i can bake them... the malaysian at least... not sure how cork will hold up to baking.
Lots of info on the interwebs but they all vary in time and heat. I cant find a concensus.
What has work for you guys?

Info appreciated greatly!
