I mean I agree it's likely that the process makes the wood lighter. But no, the article doesn't explicitly say the end result is lighter. It explicitly says it's thinner and stronger. I don't really know much about the process or whether the chemical treatment can potentially make the wood heavier/absorb some of the liquid, which would offset the weight of the material that's lost. My point wasn't that there's no way the result is lighter. My point was that the article didn't mention the weight before and after, so it seemed presumptuous to me to claim it was definitely lighter. I went to check the actual paper to confirm, hit a paywall, and so was unable to verify. I was hoping someone would comment with more details.
