塞缪尔·斯迈尔斯：自助论·摘录 92

Böttgher was, however, well aware that the white colour was an essential property of true porcelain; and he therefore prosecuted his experiments in the hope of discovering the secret. Several years thus passed, but without success; until again accident stood his friend, and helped him to a knowledge of the art of making white porcelain. One day, in the year 1707, he found his perruque unusually heavy, and asked of his valet the reason. The answer was, that it was owing to the powder with which the wig was dressed, which consisted of a kind of earth then much used for hair powder. Böttgher’s quick imagination immediately seized upon the idea. This white earthy powder might possibly be the very earth of which he was in search—at all events the opportunity must not be let slip of ascertaining what it really was. He was rewarded for his painstaking care and watchfulness; for he found, on experiment, that the principal ingredient of the hair-powder consisted of _kaolin_, the want of which had so long formed an insuperable difficulty in the way of his inquiries.
