Some of the bronze vases found at Thebes and other parts of Egypt show great skill in the art of compounding metals, and were highly polished. Their bronze knives and daggers had an elastic spring, as if made of steel. Wilkinson expresses his surprise at the porcelain vessels recently discovered, as well as admiration of them, especially of their rich colors and beautiful shapes. There is a porcelain bowl of exquisite workmanship in the British Museum inscribed with the name of Rameses II., proving that the arts of pottery were carried to great perfection two thousand years before Christ. Boxes of elaborate workmanship, made of precious woods finely carved and inlaid with ivory, are also preserved in the different museums of Europe, all dating from a remote antiquity. These boxes are of every form, with admirably fitting lids, representing fishes, birds, and animals. The rings, bracelets, and other articles of jewelry that have been preserved show great facility on the part of the Egyptians in cutting the hardest stones. The skill displayed in the sculptures on the hard obelisks and granite monuments of Egypt was remarkable, since they were executed with hardened bronze. Glass-blowing was another art in which the Egyptians excelled. Fifteen hundred years before Christ they made ornaments of glass, and glass vessels of large size were used for holding wine. Such was their skill in the manufacture of glass that they counterfeited precious stones with a success unknown to the moderns. We read of a counterfeited emerald six feet in length. Counterfeited necklaces were sold at Thebes which deceived strangers. The uses to which glass was applied were in the manufacture of bottles, beads, mosaic work, and drinking-cups, and their different colors show considerable knowledge of chemistry. The art of cutting and engraving stones was doubtless learned by the Israelites in their sojourn in Egypt. So perfect were the Egyptians in the arts of cutting precious stones that they were sought by foreign merchants, and they furnished an important material in commerce.
