I have been running into this mistaken assessment as to the temperature that one would use to " kiln " lumber. Wood is not like say glass for instance slump fires at 1200° F . That and soft woods may be cured at a more rapid manner then hard woods. As the more rapidly the moisture is removed from the wood the faster that the wood changes size etc. the effects of the processes on the soft woods are less detrimental to the integrity of the wood since by its nature is more "pliable" then hard woods. I am working with hardwoods for my 1850s camera bodies, as well as high end butcher block, chop block, end grain, cutting boards. By way of explanation, those of you that have a collection of high end blades already know that cutting against or across the grain will dull the blade, end grain is better on the blade, then face grain and or edge grain. The reason being that the two latter grains are horizontal and the end grain is vertical so that the blade cuts down into the grain and not across the fibers of the grain. This is also the reason that "real" kitchens use the thick heavy end grain cutting boards. The end grain if struck hard enough say with a proper cleaver it could split the board. Therefor that is the reason that the end grain boards are at least 2.5 inches thick, and the blocks are joined with biscuits and using an FDA approved glue and clamped for the strongest joints.

For centuries, freshly cut lumber has been allowed to dry in response to the temperature and humidity of the surrounding air, also known as the ambient conditions. The result was air-dried or air-seasoned lumber which, in Missouri, typically has a moisture content (MC) between 12 percent and 14 perc...
