Lee Valley has begun using what they call "torrefied wood" in their plane totes and knobs, which seems like the same thing as what you're explaining above. To quote: All totes are made using domestic torrefied maple – wood treated with a heating process that changes the structure of the wood at the cellular level, stabilizing it against the swelling and ...

Now, the wood is thermally modified. Which basically means it went into a kiln at a somewhat higher temperature and underwent a heat-induced chemical reaction. The thermal modification of wood into what is variously called roasted, toasted, caramelized or more technically torrefied wood takes place at significantly higher temperatures than are used in ...

Not burning or charring the wood, but heating it to a high temperature. In this article dealing with the "Strength properties of thermally modified softwoods..." that deals specifically with three different softwoods the authors present information about distinct changes that occur in the mechanical properties brought about by heat-treating. First, the ...

It's not the burning of wood, it's the heating of it. By heating it one of the things that happens is you remove the moisture from the wood. This makes it more physically stable. Letting a stick dry out in the sun will have similar properties (as long as it isn't in the rain). Moisture helps keep wood supple and when you want to push a stick into ...

To answer this question: Can I heat-treat wood in a similar manner to the quoted paper and get the results I want (resistance to rot), with none of the downsides mentioned in the same paper? The short answer is, no. For your purpose there isn't much benefit, even if it would work (which it will not), because many of the benefits of using wood for a chair ...

I have worked with both poplar and maple cambia as it is called here in Portland. Carmalizing kills the wood in a way. I believe it breaks the cell walls. Gluing and fastening are OK figuring for a small amount of loss in strength. The memory quality is lost - much harder to swell a ding back out. I made a chair out of the maple cambia ( a very good test) ...
