Glass, and a knowledge how to manufacture it, with them out of Egypt, were not the evidence of history so explicit that it was actually discovered and wrought at their own doors. Whether it was used by them for mirrors is another question. That Glass, however, was known to the Hebrews appears beyond a doubt. (Dr. Kitto's Cyclopædia of Biblical Literature; art. Glass.)

Notwithstanding so many records exist of the knowledge of Glass-making possessed by the ancients, there remain but comparatively few specimens of antiquity to prove the fact. Most writers have erroneously referred to the beads, which ornament mummies, as satisfactory evidence of Egyptian Glass-making; the majority of these, however, are composed, not of Glass, but of burnt clay, or earthenware glazed; or, perhaps, of glazed earthenware pounded, and mixed with coloured Glass, fuzed together; of such substances are the numerous small images of mummies, beetles, and other figures. There can, however, be but little doubt that the Egyptians were well acquainted with the materials for making Glass, as well as with the chemical properties of the metallic oxides for colouring it; since, among the tombs at Thebes have lately been discovered small solid pieces of Glass, of a turquoise colour, which are reasonably supposed to have been used for the glazing of the earthenware beads and figures.

Fragments of blue, white, yellow, and green Glass, have likewise been found but these may possibly have been made by the Greeks and Romans, who successively conquered Egypt; or, such specimens may have been procured from neighbouring or distant nations. One of these fragments is flat and of a circular form, resembling a coin; it is nearly entire, of an amber colour, and has a well executed figure of a
