“And he made the laver of brass, and the foot of it of brass, of the lookingglasses of the women assembling, which assembled at the door of the tabernacle of the congregation.”

Here metal, highly polished, must certainly be meant, as glass was not yet in use; and had it even been in use, we are sure that looking-glasses could not make a Brazen laver. The word therefore should be rendered mirrors, not looking-glasses, which in the above verse is perfectly absurd, because from those maroth the brazen laver was made. The first mirrors known among men were the clear, still fountain, and unruffled lake; and probably the mineral called mica, which is a very general substance through all parts of the earth. Plates of it have been found of three feet square, and it is so extremely divisible into laminae, that it has been divided into plates so thin as to be only the three hundred thousandth part of an inch. A plate of this forms an excellent mirror when any thing black is attached to the opposite side. A plate of this mineral, nine inches by eight, now lies before me; a piece of black cloth, or any other black substance, at the back, converts it into a good mirror; or it would serve as it is for a square of glass, as every object is clearly perceivable through it. It is used in Russian ships of war, instead of glass, for windows. The first artificial mirrors were apparently made of brass, afterwards of polished steel, and when luxury increased they were made of silver; but they were made at a very early period of mixed metal, particularly of tin and copper, the best of which, as Pliny tells us, were formerly manufactured at Brundusium.
