was known to the Egyptians at a very early period of their national history, at least B.C. 1500. Various articles both useful and ornamental were made of it, as bottles, vases, etc. A glass bottle with the name of Sargon on it was found among the ruins of the north-west palace of Nimroud. The Hebrew word zekukith ( Job 28:17 ), rendered in the Authorized Version "crystal," is rightly rendered in the Revised Version "glass." This is the only allusion to glass found in the Old Testament. It is referred to in the New Testament in Revelation 4:6 ; 15:2 ; Revelation 21:18 Revelation 21:21 . In Job 37:18 , the word rendered "looking-glass" is in the Revised Version properly rendered "mirror," formed, i.e., of some metal. (Compare Exodus 38:8 : "looking-glasses" are brazen mirrors, RSV). A mirror is referred to also in James 1:23 .
The Hebrew word occurs only in ( Job 28:17 ) where in the Authorized Version it is rendered "crystal." In spite of the absence of specific allusion to glass in the sacred writings, the Hebrews must have been aware of the invention from paintings representing the process of glass-blowing, which have been discovered at Beni-hassan, and in tombs at other places, we know that the invention vas known at least 3500 years ago. Fragments too of wine-vases as old as the exodus have been discovered in Egypt. The art was also known to the ancient Assyrians. In the New Testament glass is alluded to as an emblem of brightness. ( Revelation 4:6 ; 15:2 ; 21:18 )
glas (zekhukhith; hualos):
Glass is of great antiquity. The story of its discovery by accident, as related by Pliny (NH, xxxvi.65), is apocryphal, but it was natural for the Greeks and Romans to ascribe it to the Phoenicians, since they were the producers of the article as known to them. The Egyptian monuments have revealed to us the manufacture in a time so remote that it must have preceded that of the Phoenicians. A representation of glass-blowing on monuments of the Old Empire, as formerly supposed, is now regarded as doubtful, but undoubted examples of glazed pottery of that age exist. A fragment of blue glass has been found inscribed with the name of Antef III, of the XIth Dynasty, dating from 2000 or more BC (Davis, Ancient Egypt, 324). The oldest dated bottle, or vase, is one bearing the name of Thothmes III, 1500 or more BC, and numerous examples occur of later date. The close connection between Egypt and Syria from the time of Thothmes on must have made glass known in the latter country, and the Phoenicians, so apt in all lines of trade and manufacture, naturally seized on glass-making as a most profitable art and they became very proficient in it. The earliest glass was not very transparent, since they did not know how to free the materials used from impurities. It had a greenish or purplish tinge, and a large part of the examples we have of Phoenician glass exhibit this. But we have many examples of blue, red and yellow varieties which were purposely colored, and others quite opaque and of a whitish color, resembling porcelain (Perrot and Chipiez, Art in Ancient Phoenicia and Its Dependencies). But both they and the Egyptians made excellent transparent glass also, and decorated it with brilliant coloring on the surface (ib; Beni Hasan, Archeol. Survey of Egypt, Pt IV). Layard (Nineveh and Babylon) mentions a vase of transparent glass bearing the name of Sargon (522-505 BC), and glass was early known to the Babylonians.
Phoenicia was the great center, and the quantities found in tombs of Syria and Palestine go to confirm the statement that this was one of the great industries of this people, to which ancient authors testify (Strabo, Geog.; Pliny, NH). Josephus refers to the sand of the Belus as that from which glass was made (BJ, II, x, 2). It seems to have been especially adapted for the purpose, but there are other places on the coast where plenty of suitable sand could be obtained. The potash required was obtained by burning certain marine and other plants, and saltpeter, or niter, was also employed. The manufacture began centuries BC on this coast, and in the 12th century AD a factory is mentioned as still being worked at Tyre, and the manufacture was later carried on at Hebron, even down to recent times (Perrot and Chipiez).
Both the Egyptians and Phoenicians gained such proficiency in making transparent and colored glass that they imitated precious stones with such skill as to deceive the unwary. Necklaces are found composed of a mixture of real brilliants and glass imitations. Cut glass was manufactured in Egypt as early as the XVIIIth Dynasty, and diamonds were made use of in the article Glass composed of different colors in the same piece was made by placing layers of glass wire, of different colors, one above the other and then fusing them so thar they became united in a solid mass without intermingling. Colored designs on the surface were produced by tracing the patterns, while the glass was still warm and plastic, deep enough to receive the threads of colored glass which were imbedded in them. The whole was heated again sufficiently to fuse the threads and attach them to the body. The surface was then made even by perishing. By this process vessels and ornaments of very beautiful design were produced. Many of the specimens, as found, are covered by an exquisite iridescence which is due wholly to the decomposition of the surface by chemical action, from lying buried for centuries in the soil which thus acts upon it. This is often lost in handling by the scaling off of the outer surface.
Glass, in the strict sense, is rarely mentioned in Scripture, but it was certainly known to the Hebrews, and occurs in Job 28:17 (translated "crystal" in the King James Version). Bottles, cups and other vessels in glass must have been in use to some extent. The wine cup of Proverbs 23:31 and the bottle for tears mentioned in Psalms 56:8 were most likely of glass. Tear bottles are found in great quantities in the tombs throughout the land and were undoubtedly connected with funeral rites, the mourners collecting their tears and placing them in these bottles to be buried with the dead. As mourners were hired for the purpose, the number of these bottles would indicate the extent to which the deceased was honored. These were, of course, small, some quite diminutive (see illustration), as also were the vials or pots to contain the ointment for the eyebrows and eyelashes, used to heighten the beauty of the women, which was probably a custom among the Hebrews as well as their neighbors. Rings, bracelets and anklets of glass are very common and were doubtless worn by the Hebrew women (see Isaiah 3:18 f). In the New Testament the Greek hualos occurs in Revelation 21:18,21, and the adjective derived from it hualinos in 4:6 and 15:2. In the other passages, where in the King James Version "glass" occurs, the reference is to "looking-glass," or mirror, which was not made of glass, but of bronze, and polished so as to reflect the light similar to glass. The Hebrew word for this is gillayon (Isaiah 3:23), or mar'ah (Exodus 38:8), and the Greek esoptron (1 Corinthians 13:12; James 1:23; compare The Wisdom of Solomon 7:26; Sirach 12:11).
The composition of the Phoenician glass varies considerably. The analysis shows that, besides the ordinary constituents of silica, lime, lead, potash or soda, other elements are found, some being used for the purpose of coloring, such as manganese to give the purplish or violet hue, cobalt for blue, copper for red, etc. The articles illustrated above are of ordinary transparent glass with an iridescent surface, caused by decomposition, as mentioned above, indicated by the scaly appearance. Numbers 1, 4 and 5 are tear bottles, number 4 being only 1 3/4 inches in height; numbers 2 and 3 are ointment vases which were used for the ointment with which ladies were accustomed to color their eyebrows and eyelashes to enhance their beauty. This custom still prevails in the East. The small ladle by the side of the larger vase is of bronze, used in applying the ointment. This vase is double and 6 3/4 inches high, ornamented with glass wire wound upon it while plastic. The larger vases (numbers 6 and 7) are about 6 inches in height. The hand-mirror ("looking-glass" the King James Version) is bronze, and had originally a polished surface, but is now corroded.
