What is the first main method for drying wood?

• A. Kiln drying
• B. Air drying
• C. Freeze drying
• D. Solar drying

Answer: (B)

Drying timber starts with air drying because it uses natural air flow to slowly evaporate moisture from the wood. This initial stage is cheap and gentle, suitable for large pieces, and helps reduce moisture gradually without introducing stresses that could cause warping or cracking. Once most of the moisture has been removed in this way, kiln drying can be used to speed up the remaining drying and bring the wood to a precise moisture content. Freeze drying isn’t practical for timber due to the energy and equipment required, and while solar drying is a form of air drying, it depends on sunny, dry weather and is slower and less controllable, so it isn’t the standard first method in most contexts.
