Thank you very much for your long and elaborated explanation about long and short chain molecules and their importance in the process of torrefication.
I am probably one of those ignorant persons you not very nicely refer to. My approach is more pragmatic (and guided by experience as well) and I like to ask "What is it good for?", so my basic question simply is:
- Which direct consequences has a torrefied top for the sound of a guitar?
- Or why else should we use torrefied material in building a guitar if not for the sound?
In the past I made a few guitars with "heat-treated" spruce that I bought from a sawmill or had commercially treated by a company where I sent my tops to. All I can say from my experiences is "I do not like it!", I did not like to work with it, it took some time until I found the right glue, dents and dings during the building process could not be dampened out (I did find out the hard way), it was rather prone to cracking (as I did experience with a guitar I made and that came back) - I did not like it. Soundwise the guitars already had some sort of an "aged" sound (not bad I have to admit) but not very much potential for further development in sound as a spruce top usually has - again I did not like it. It looked phantastic under shellac - that's what I liked very much!
Finally I decided not to go on with it, and my decision was guided by my personal experience and not by the knowledge about short and long chain molecules.
So, please be careful in your anger, there might be more aspects beyond science! Thank you.
@ Grenner: There is a company in Austria where you can send your tops for treatment.
