The combustion process or “fire” is sometimes called “rapid oxidation.” It is similar to the formation of rust on iron or the decay of dead wood in the forest, except that the process is drastically speeded up. ... temperature of the fuel is raised to the point where gases start to volatize. Pre-ignition – volatile materials in the ...
But wood has many components and it is not a type of crystalline material. Before you heat it to the melting point, some components including lignin and cellulose will oxidize to burn. In this case, wood does not have a melting point, it only has a combustion point. Any wood will just burn like wood pellets in the stove.
3. Using the Transfer Point, press firmly, rubbing continuously in a circular motion on the back of the image. 4. Lift the paper image often to make sure the image is transferring. 5. When transferring an image to wood, use sandpaper to correct any mistakes. Made in China.

Stable, seasoned wood probably doesn't being liberating more volatiles (remember it looses some with the moisture in seasoning/kilning) until exposure to a significant amount of heat. Funny you mentioned the blackened wood as that will take higher temperature to combust. I've got some of that in my house.

Firewood should have a moisture content of below 30% at least for burning. The density of the wood also affects how long it needs to be seasoned for. Oak is a very dense wood and can take up to 2 years to season fully. The following is a list of common firewoods with a brief description of their burning characteristics.
Burning wood is a complex chemical reaction. When it starts initially, all that happens is the water in the wood evaporates or vaporizes. This process uses the initial energy of the reaction, and ...
The tests of the 1-in cube punky wood sample on the laboratory hot plate with steady heating (see table 2) was found smoking at 230° C (446F° ) and was totally consumed by glowing combustion within 7 minutes after the initial combustion on exposure to 300° C (572° F) for 40 sec.
Stoichiometric or Theoretical Combustion is the ideal combustion process where fuel is burned completely. A complete combustion is a process burning all the carbon (C) to (CO 2), all the hydrogen (H) to (H 2 O) and all the sulphur (S) to (SO 2).. With unburned components in the exhaust gas such as C, H 2, CO, the combustion process is uncompleted and not stoichiometric .
