Moses states that the women who waited all night at the door of the tabernacle, cheerfully offered their looking glasses, to be employed in making a brazen laver for the purification of the priests, Exodus 38:8 . These looking glasses were doubtless of brass, since the basin here mentioned, and the basis thereof, were made from them. The ancient looking glasses were mirrors, not made of glass as ours; but of brass, tin, silver, and a mixture of brass and silver, which last were the best and most valuable.
