Timber MCQ with answer and solution

Concept

In chemical (salt) seasoning, timber is soaked in a salt solution and then dried in the normal way.

Step-by-step solution

1. Read the method: timber is put in a salt solution, then taken out and dried in the normal way. 2. Using a salt solution (such as urea or common salt) is called chemical or salt seasoning. 3. So the answer is (B) Chemical seasoning.

Explanation

In chemical seasoning, timber is first dipped in a suitable salt solution. The salt makes the outer layers dry more slowly, so the inner and outer parts dry at nearly the same rate. This reduces cracks and warping. After this, the timber is dried in the normal way.

Why the other options are wrong

A: Boiling means heating timber in water or steam, not in a salt solution. C: Kiln seasoning dries timber with hot air in a closed chamber. D: Water seasoning keeps timber in running water to remove sap.

Shortcut

Salt solution = Chemical (salt) seasoning.

Common mistake

Confusing it with water seasoning, because both involve dipping timber in a liquid.
