SEASONING

Removal of moisture from timber so as to be in equilibrium with moisture in surrounding atmospheric conditions, where

timber is likely to be used, is called as seasoning.

OBJECTIVES OF SEASONINGOBJECTIVES OF SEASONING

Seasoning improves following properties:Seasoning improves following properties: StrengthStrength DurabilityDurability Working qualities including polishing, painting, and Working qualities including polishing, painting, and
