Solar Wood Drying

INTRODUCTION TO KILN DRYING

content can change somewhat after it's been dried In dry air the wood gives up water to the air until it is dried as it equalizes with the air When the air is more humid wood absorbs water from the air Wood expands when it absorbs water and shrinks when it gives up water In worst-case winter heated conditions in northern climates
