Is it a good idea to make torrefied wood cookware?

I like the look and feel of torrefied wood and wa thinking about making torrefied wood tables for serving pizza in a restaurant that I am starting with a partner. However I could not find examples of this being made before.

So my questions are:

Is this a good idea?
Would it be unhealthy in any way?
Any advice on how to do it?
Any examples or resources you know of?

I thod it might contain toxic substances, howevwe, wood cookware gets torrefied over time and Ive never heard of it being unhealthy.

Thank you ver much.
