I got a plan for a toy dump truck and it showed using thermally treated or heat treated wood. If done right, it can darken a wood anywhere from a light caramel to almost a dark brown.

Has anyone have any experience either heat treating wood or working with heat treated wood.

I read some articles about the commercial heat treatment and they use a couple of different furnaces including a vacuum furnace and others a combination of steam and heat. The toy dump truck website just said to use an oven a 400°F for 30-60 minutes.

I concerns about cutting this wood, glueing it and even finishing it as it will come out of the oven with zero moisture. I probably would have to let it re-adjust to some moisture level.

I am hoping that someone has some helpful ideas about this. Worst case is that I will need to make some pieces of a couple of kinds of wood and try the heat treatment with some variation in time. I do have some concerns about using my wife’s oven.

Here is an article which may be of some help.

The treating process is done before you use the wood which changes the properties, some pros and some cons.

I’ve used heat treated poplar, it turned brown and looked like a light walnut. (I have a pic if interested).
Never done it in the oven though.
