From Ibn Al-Haytam’s optical lenses and Ibn Hayyan’s chemistry flasks to a mosque lamp of Amir Qawsun, Muslim Civilisation played a major role in inspiring the growth of glass industry from the 8th century onwards.
Mosques, houses and cities were transformed into beautiful spaces richly decorated with glass. Beauty and functionality were both essential elements of design in Muslim Civilisation. Possibly in an effort to supply the thousands of mosques, and also thanks to the input provided by the thriving scientific activity in fields such as optics and chemistry, glassmakers in Muslim Civilisation turned - what had up till then been - a craft into an industry employing new techniques and large number of workers from different parts of the Muslim Civilisation.
Under Islam, the glass industry witnessed a revival. The old centres flourished and new ones were established. The remarkable, sumptuous Islamic glass treasures which are distributed among museums throughout the world, bear witness to the high artistic and technological level of Islamic glass."

"... Similar bottles are in museums in Saint Petersburg, Kiev, and Berlin. That a majority of these examples were reportedly found in the Caucasus region or along the coast of the Black Sea suggests that they were part of the well-established glass trade between Syria, northwestern Asia, and eastern Europe"
Throughout the Muslim Civilisation glassware was produced in vast amounts from the 8th century either by blowing liquid glass into holds or by cutting it from crystal. Glassmakers in Syria and Egypt inherited the Roman glass industry and improved it by developing their own technique perfecting glass decoration and colouring, and expanding the variety of products.
Muslim and non-Muslim glassmakers working in the Islamic areas, however, were extraordinarily creative and, in tune with the general evolution of Islamic art, brought this craft to a new technical, technological, and artistic heights."
*Meri, J. W. “Medieval Islamic Civilization: An Encyclopedia”; Routledge, 31 Oct 2005; Page 297.
Excavation work in Syria and other parts of the Muslim Civilisation uncovered a huge amount of glassware. Aleppo in Syria was mentioned as a glassmaking and decorating centre by the geographers Yaqut Al-Hamwi (d. 1229) and Al-Qazwini (d. 1283). Damascus, too, was described as a glassmaking centre by Ibn Battuta (d. 1377). Egypt, Iraq and Andalusia were also all producing glass in vast quantities.
Glass from the Muslim Civilisation, and especially that from Syria, was highly prized the world over. Glass objects were discovered in medieval European sites in Sweden, and Souther Russia. Even such fragile objects as Syrian enamelled glass of the 13th century have been found in Sweden.

In the early 14th century, more than 300 years after Ibn Sahl, Maragha astronomer-mathematician Kamal al-Din al-Farisi experimented with a glass sphere filled with water to analyze the way sunlight breaks into the spectrum colors of a rainbow. The rays that produced the colours of the rainbow, he observed:
... were refracted upon entering his glass sphere, underwent a total internal reflection at the back surface of the glass sphere (which sent them back toward the observer), and experienced a second refraction as they exited the sphere. This occurred in each droplet within a mist to produce a rainbow."

"the makers of such objects may have been seeking ways to achieve some freedom of expression within the rules of repetition common in Islamic art. This freedom could be achieved by using different combinations of tongs, which bore patterns different from those of one- or two-part molds. Archeological finds indicate that this type of glass was traded extensively in the Islamic world during the ninth and 10th centuries."

The technique of cutting crystal was said to have been introduced by ‘Abbas ibn Firnas (d. 887), scholar and inventor in the courts of ‘Abd al-Raḥman II and Muḥammad I. It is worth pointing here to the genius of Ibn Firnas, who was not only able to decipher the most complex writing, but also made attempts at flying by building artificial wings. In relation to glass, he was familiar with the scientific properties of glass, and contributed to the early experiment with lenses and the idea of magnifying script by their use. He also lent his skills to the glass making furnaces of Cordoba, and made a representation of the sky in glass, which he was able at will to make clear or cloudy, with lightning and the noise of thunder at the press of a finger.

"The rise of Islam, and the resulting expansion of Muslim territories through the seventh century A.D., ultimately gave rise to a society that kept alive many of the achievements that were lost in the west. Mosaic glass, cast and cut vessels, and free- and mold-blown wares continued to be made, and starting in the ninth century, new decorative approaches emerged. The principal advance began with the discovery that glass could be painted with metallic stains, resulting in a type of glass known as lustre ware because of its distinctive sheen. This was the first stained glass."*
9.1 Window in stained glass, 17th century, Egypt or Syria (Ottoman period?) (38.7 x 48.3 cm). A window such as this with brightly coloured panes in blue, orange, green, and red might have been found in a room of an aristocratic home in the Islamic world. Tinted glass was favoured because it filtered the light, but it also complemented the multihued furnishings of the room.
German art historian Otto von Simson explained the origin of the rose window by comparing the idea to the six-sided rosettes and octagon window on the outside wall of the Umayyad palace Khirbat al-Mafjar, built in the Holy Land in about 750 CE. The theory is that Crusaders saw such windows and brought the idea back to Europe, introducing it into churches."
10.1 Mosque Lamp of Amir Qawsun, ca. 1329–35 (Source)
"... Large glass lamps of this type were commissioned by sultans and members of their court for mosques, madrasas (Qur'anic schools), tombs, hospices, and other public buildings in fourteenth-century Mamluk Cairo. This example bears the name of its patron, Qawsun (d. 1342), amir of the Sultan al-Nasir Muhammad ibn Qalaun (r. 1293–1341 with brief interruptions), and was probably intended for one of his two architectural commissions in Cairo—a mosque or a tomb-hospice complex."

... The first painters of glass in the Islamic world applied a brownish or yellowish metallic pigment on bowls, dishes, and other objects. The decoration usually consists of animal or vegetal motifs, sometimes accompanied by inscriptions. By applying pigments to both sides of these objects, glassmakers could highlight details or exploit the transparency of the glass to produce subtle shading effects..."

Some of the most sophisticated Egyptian glass vessels were decorated with lustre. This shiny, sometimes metallic effect was achieved by painting copper or silver oxide on the surface of the object, which was then fired at a temperature of about 600°C (1112°F) in reducing conditions. The same technique, as already noted, was used in the decoration of earthenware, not only in Egypt but also in Iraq and Iran. Until recently, controversy raged over the origin of lustre painting, but the problem appears to have been solved by the discovery at Al-Fustat, of a glass cup of local type, inscribed with the name of ‘Abd al-Hamad, governor of Egypt in 771-772; Egyptian glass painters were therefore using lustre some time before its appearance in Iraq.

"At once decorative and functional, the delicately applied trailing designs on the present hanging lamp cover almost its entire surface. Composed of deep blue glass, these trailing motifs act as contrasts to the yellowish body of the vessel. Stefano Carboni links this type of decoration to the late Roman period, the production of which was extended into the early Islamic period, and at first limited to: "areas that were once part of the Roman and Byzantine Empires, including Egypt, Syria, and Mesopotamia" (Carboni 2001, p. 163)

"... Its decoration is probably inspired by contemporary manuscript paintings and depicts courtly figures and scenes of royal pastimes, such as hunting and polo."
Contact between the Byzantine Empire and the new empire of Islam allowed Islamic glassmakers to add the known Roman and Byzantine glassmaking techniques to their own glassmaking knowledge. As with many chemical arts, this cumulative glassmaking knowledge was then preserved by the world of Islam until the coming of the Renaissance in the West. In Islam glassmaking flowered again for a time, combining Roman knowledge with indigenous traditions..."

In Al-Andalus, glass vessels were blown in Almeria, Malaga, and Murcia in imitation of eastern wares, such as the irakes –glass goblets– so favoured on the noble tables of 10th-century León. The technique of cutting crystal was said to have been introduced by ‘Abbas ibn Firnas (d. 887), scholar and inventor in the courts of ‘Abd al-Raḥman II and Muḥammad I. It is worth pointing here to the genius of Ibn Firnas, who was not only able to decipher the most complex writing, but also made attempts at flying by building artificial wings.

There is an excellent passage by al-Farabi (870-950), which proves that Muslims used telescopes and other sighting devices for the observation of the planets at quite an early date. His passage on the science of mechanics and other devices includes:
"The optical devices used in the production of instruments that direct the sight in order to discern the reality of the distant objects, and in the production of mirrors upon which one determines the points that reverse the rays by deflecting them or by reflection or refraction. With this, one can also determine the points that reverse the sun’s rays into other bodies, thus producing the burning mirrors and the devices connected with them." Al-Farabi*

Glass changed the course of the history. For example, it is said that - the inventors of gunpowder, paper, printing, and the compass -Chinese did not make much advances in technology after 14th Century because they simply preferred porcelain tea cup over wine glass: “The invention of glass meant that we also had the technology of lens grinding, telescopes and microscopes. The invention of spectacles meant that intellectuals and scientists had an extra 15-20 years of a reading and active life. Also came the invention of beakers, flasks and retorts, which was useful because glass is chemically neutral. Between the 14th century and the 19th century, no glass was made in China. It also meant that they had no mirrors and their windows were made out of paper, which meant they had dark houses. So, the point is that since they liked drinking tea from the teacup, they never bothered to try to invent glass.”*

18.1 Nasīr al-Mulk Mosque in Shiraz, Iran
"The designers Muhammad Hasan-e-Memar and Muhammad Reza Kashi Paz-e-Shirazi used extensively stained glass on the façade and other traditional elements such as panj kāseh-i (five concaves), which create a breath taking effect of the interior like standing in a kaleidoscope. Once the sunlight hits the stained glass, the entire building is flooded by a vibrant rainbow of colours. In popular culture, the mosque is also called Pink Mosque, because its tiles are beautifully decorated with a pre-eminently pinkish rose colour."

"Al-Tusi made his observations without telescopes or even glasses," says Djebbar, removing his own spectacles and waving them theatrically in the air. "Even though the Arabs possessed the knowledge to make lenses, they probably thought it was an idiotic idea. God made us like this; why hang something on our noses to see better?" he jokes, placing his glasses back on his nose with a flourish. His audience erupts into laughter as Djebbar, who was curator of "The Golden Age of Arabic Sciences"—the Paris exhibition, which ran from October 2005 through March 2006 at the Arab World Institute—tries to quiet them down."
