9th century 10th century 11th-12th centuries 13th century
  • Fritware: It refers to a type of pottery which was first developed in the Near East, beginning in the late 1st millennium, for which frit was a significant ingredient. A recipe for "fritware" dating to c. 1300 AD written by Abu’l Qasim reports that the ratio of quartz to "frit-glass" to white clay is 10:1:1. [116] This type of pottery has also been referred to as "stonepaste" and "faience" among other names. [117] A 9th-century corpus of "proto-stonepaste" from Baghdad has "relict glass fragments" in its fabric. [118]
  • Mercury clock: A detailed account of technology in Islamic Spain was compiled under Alfonso X of Castile between 1276 and 1279, which included a compartmented mercury clock, which was influential up until the 17th century. [119] It was described in the Libros del saber de Astronomia, a Spanish work from 1277 consisting of translations and paraphrases of Arabic works. [120]
  • Mariotte's bottle: The Libros del saber de Astronomia describes a water clock which employs the principle of Mariotte's bottle. [119]
  • Metabolism: Ibn al-Nafees is the first scientist in history to describe metabolism. [121]
  • Naker: Arabic nakers were the direct ancestors of most timpani, brought to 13th-century Continental Europe by Crusaders and Saracens. [122]
  • Tusi couple: Nasir al-Din al-Tusi was the first astronomer to attempt a solution which would provide for latitudinal motion without introducing a longitudinal component.

  • Hispano-Moresque ware: This was a style of Islamic pottery created in Arab Spain, after the Moors had introduced two ceramic techniques to Europe: glazing with an opaque white tin-glaze, and painting in metallic lusters. Hispano-Moresque ware was distinguished from the pottery of Christendom by the Islamic character of its decoration. [133]
  • Polar-axis sundial: Early sundials were nodus-based with straight hour-lines, indicating unequal hours (also called temporary hours) that varied with the seasons, since every day was divided into twelve equal segments; thus, hours were shorter in winter and longer in summer. The idea of using hours of equal time length throughout the year was the innovation of Abu'l-Hasan Ibn al-Shatir in 1371, based on earlier developments in trigonometry by Muhammad ibn Jabir al-Harrani al-Battani (Albategni). Ibn al-Shatir was aware that "using a gnomon that is parallel to the Earth's axis will produce sundials whose hour lines indicate equal hours on any day of the year." His sundial is the oldest polar-axis sundial still in existence. The concept later appeared in Western sundials from at least 1446. [134] [135]
Sultanates12th century
  • Blood measurement device: Created by Al-Jazari [136]
  • Double-acting principle: The principle was used by al-Jazari in his water pumps. [137]
  • Tadelakt: The history of the material dates back to the 12th century, in the Almoravid and Almohad dynasties. [138]
13th century
  • Various automatons: Al-Jazari's inventions included automaton peacocks, a hand-washing automaton, and a musical band of automatons. [139] [140] [141]
  • Camshaft: The camshaft was described by Al-Jazari in 1206. He employed it as part of his automata, water-raising machines, and water clocks such as the castle clock. [142]
  • Candle clock with dial and fastening mechanism: The most sophisticated candle clocks known were those of Al-Jazari in 1206. [143] It included a dial to display the time. [144]
  • Crankshaft: Al-Jazari (1136–1206) is credited with the invention of the crankshaft. [34] He described a crank and connecting rod system in a rotating machine in two of his water-raising machines. [145] His twin-cylinder pump incorporated a crankshaft, [146] including both the crank and shaft mechanisms. [147]
  • Crank-slider: Ismail al-Jazari's water pump employed the first known crank-slider mechanism. [148]
  • Cotton gin with worm gear: The worm gear roller gin was invented in the Delhi Sultanate during the 13th to 14th centuries. [149]
  • Design and construction methods: English technology historian Donald Hill wrote, "We see for the first time in al-Jazari's work several concepts important for both design and construction: the lamination of timber to minimize warping, the static balancing of wheels, the use of wooden templates (a kind of pattern), the use of paper models to establish designs, the calibration of orifices, the grinding of the seats and plugs of valves together with emery powder to obtain a watertight fit, and the casting of metals in closed mold boxes with sand." [150]
  • Draw bar: The draw bar was applied to sugar-milling, with evidence of its use at Delhi in the Mughal Empire by 1540, but possibly dating back several centuries earlier to the Delhi Sultanate. [151]
  • Minimising intermittence: The concept of minimising the intermittence is first implied in one of Al-Jazari's saqiya devices, which was to maximise the efficiency of the saqiya. [152]
  • Programmable automaton and drum machine: The earliest programmable automata, and the first programmable drum machine, were invented by Al-Jazari, and described in The Book of Knowledge of Ingenious Mechanical Devices, written in 1206. His programmable musical device featured four automaton musicians, including two drummers, that floated on a lake to entertain guests at royal drinking parties. It was a programmable drum machine where pegs ( cams) bump into little levers that operated the percussion. The drummers could be made to play different rhythms and different drum patterns if the pegs were moved around. [153]
  • Tusi couple: The couple was first proposed by Nasir al-Din al-Tusi in his 1247 Tahrir al-Majisti (Commentary on the Almagest) as a solution for the latitudinal motion of the inferior planets. The Tusi couple is explicitly two circles of radii x and 2x in which the circle with the smaller radii rotates inside the Bigger circle. The oscillatory motion be produced by the combined uniform circular motions of two identical circles, one riding on the circumference of the other.
  • Griot: The griot musical tradition originates from the Islamic Mali Empire, where the first professional griot was Balla Fasséké. [154]
  • Segmental gear: A segmental gear is "a piece for receiving or communicating reciprocating motion from or to a cogwheel, consisting of a sector of a circular gear, or ring, having cogs on the periphery, or face." [155] Professor Lynn Townsend White, Jr. wrote, "Segmental gears first clearly appear in al-Jazari". [156]
  • Sitar: According to various sources, the sitar was invented by Amir Khusrow, a famous Sufi inventor, poet, and pioneer of Khyal, Tarana and Qawwali, in the Delhi Sultanate. [157] [158] Others say that the instrument was brought from Iran and modified for the tastes of the rulers of the Delhi Sultanate and Mughal Empire. [158]
  • Torpedo: The concept of a torpedo existed many centuries before it was later successfully developed. In 1275, Hasan al-Rammah described "...an egg which moves itself and burns". [159]

  • Coffee: Stories exist of coffee originating in Ethiopia, but the earliest credible evidence of either coffee drinking or knowledge of the coffee tree appears in the middle of the 15th century, in the Sufi monasteries of the Yemen in southern Arabia. [163] [164] It was in Yemen that coffee beans were first roasted and brewed as they are today. From Mocha, coffee spread to Egypt and North Africa, [165] and by the 16th century, it had reached the rest of the Middle East, Persia and Turkey. From the Muslim world, coffee drinking spread to Italy, then to the rest of Europe, and coffee plants were transported by the Dutch to the East Indies and to the Americas. [166]
  • Dardanelles Gun: The Dardanelles Gun was designed and cast in bronze in 1434 by Munir Ali. The Dardanelles Gun was still present for duty more than 340 years later in 1807, when a Royal Navy force appeared and commenced the Dardanelles Operation. Turkish forces loaded the ancient relics with propellant and projectiles, then fired them at the British ships. The British squadron suffered 28 casualties from this bombardment. [167]
  • Iznik pottery: Produced in Ottoman Turkey as early as the 15th century AD. [168] It consists of a body, slip, and glaze, where the body and glaze are "quartz-frit." [169] The "frits" in both cases "are unusual in that they contain lead oxide as well as soda"; the lead oxide would help reduce the thermal expansion coefficient of the ceramic. [170] Microscopic analysis reveals that the material that has been labeled "frit" is "interstitial glass" which serves to connect the quartz particles. [171]
  • Standing army with firearms: The Ottoman military's regularized use of firearms proceeded ahead of the pace of their European counterparts. The Janissaries had been an infantry bodyguard using bows and arrows. During the rule of Sultan Mehmed II they were drilled with firearms and became "the first standing infantry force equipped with firearms in the world." [172]

  • Classical Oriental carpet: By the late fifteenth century, the design of Persian carpets changed considerably. Large-format medallions appeared, ornaments began to show elaborate curvilinear designs. Large spirals and tendrils, floral ornaments, depictions of flowers and animals, were often mirrored along the long or short axis of the carpet to obtain harmony and rhythm. The earlier "kufic" border design was replaced by tendrils and arabesques. All these patterns required a more elaborate system of weaving, as compared to weaving straight, rectilinear lines. Likewise, they require artists to create the design, weavers to execute them on the loom, and an efficient way to communicate the artist's ideas to the weaver. Today this is achieved by a template, termed cartoon (Ford, 1981, p. 170 [180]). How Safavid manufacturers achieved this, technically, is currently unknown. The result of their work, however, was what Kurt Erdmann termed the "carpet design revolution". [181] Apparently, the new designs were developed first by miniature painters, as they started to appear in book illuminations and on book covers as early as in the fifteenth century. This marks the first time when the "classical" design of Islamic rugs was established. [182]

  • Hookah or water pipe: according to Cyril Elgood (PP.41, 110), the physician Irfan Shaikh, at the court of the Mughal emperor Akbar I (1542–1605) invented the Hookah or water pipe used most commonly for smoking tobacco. [183] [184] [185] [186]
  • Metal cylinder rocket: In the 16th century, Akbar was the first to initiate and use metal cylinder rockets known as bans, particularly against war elephants, during the Battle of Sanbal. [187]
  • Multi-barrel matchlock volley gun: Fathullah Shirazi (c. 1582), a Persian polymath and mechanical engineer who worked for Akbar, developed an early multi-shot gun. Shirazi's rapid-firing gun had multiple gun barrels that fired hand cannons loaded with gunpowder. It may be considered a version of a volley gun. [188] One such gun he developed was a seventeen-barrelled cannon fired with a matchlock. [189]
  • Seamless celestial globe: It was invented in Kashmir by Ali Kashmiri ibn Luqman in 998 AH (1589–1590), and twenty other such globes were later produced in Lahore and Kashmir during the Mughal Empire. Before they were rediscovered in the 1980s, it was believed by modern metallurgists to be technically impossible to produce metal globes without any seams. [190]
