Maybe the key here is "sealed container of air" vs. unsealed. I am able to dry out a soundboard simply by heating the area around it up, but I have to vent it to allow moisture from the wood to escape... Just an average joe trying to understand. - Sorry, guys. - - I've taught science too many years to accept that the relative humidity - change has anything to do with the change in wood moisture content. - Relative humidity changes as temperature changes, but the actual amount of - moisture may indeed stay the same. I understand all about dew point, etc., - but actual moisture content does not change because the relative humidity - does UNLESS the temperature stays the same. - - A sealed container of air (or wood)may hold X amount of moisture. If it is - heated, its relative humidity goes down, because it is capable of holding - more moisture at a higher temperature. The converse is true upon cooling. - True, wood being a solid, there is less difference caused by temperature - than in air. But the content doesn't necessarily change with the relative - humidity reading which depends upon the temperature at which the humidity - reading is taken. - - Ray T.
