What effect did firing have on the surface of seals?
Answer and explanation
Correct answer: It became hard
The governing concept is heat treatment in craft production. Harappan seals were commonly made from steatite; after designs were engraved, firing transformed the material and hardened its surface. This made the seal more durable for repeated impressions. Therefore, option D is correct. Softening, dissolving in water, or becoming wood-like does not describe the purpose or result of firing the seal.
