Maybe this has been covered before, but I have not found it...
The whole drying of wood concept seems a bit confusing.
If we start with green wood (mostly what I have), we need to get it to dryness in some fashion. The easiest is to let nature take care of it and leave the wood to dry naturally outdoors. This takes a long time and usually results in cracked/checked wood that is unsuitable. Reason: Water is drawn from the wood too quickly on the ends.
In order to reduce the cracking/checking, we try to slow down the drying process with paper bags, wax coatings, etc. This would indicate that slowing the exit of moisture from the wood ends reduces the cracks. (flawed logic perhaps?)
Another method of removing moisture is DNA soaking. As I understand it, the DNA replaces the water in the wood. Then we are back to some method to control the rate of DNA exiting the wood with bags or coatings. The DNA drying is considerably faster than the water - but seems contradictory to slowing the removal of "liquid" from the wood to prevent cracking.
Then we have the kiln drying aspect (this is the really confusing part...). Here we force the moisture from the wood at an accelerated rate with heat, and yet, do not have the cracking/checking that would seem to be indicated as reasons for bags and coating use for drying at home.
Have I missed something? I guess the simple question from my long winded description is:
Why does kiln dried (or microwaved) wood not crack during the process if moisture is being removed at an faster rate than other drying methods?
