"Early humans shaped and scraped clay to make vessels, cooked in them and realised they hardened, learned to make them impervious to water, and also to decorate them, with incisions and with glazes made from salts and metals. All pots are different, and all resemble each other (except for some defiant modern monsters). They are made elementally, using earth, air, fire and water. They represent the arts of peace, domestication, and elegance, whether of pure simplicity of form or of bravura demonstration of difficult mastery of techniques and images. They are where art meets craft, the useful meets the beautiful."
