The iron pillar of Delhi (375—413). Dagger and its scabbard, India, 17th—18th century. Blade: Damascus steel inlaid with gold; hilt: jade; scabbard: steel with engraved, chased and gilded decoration. Akbarnama—written by August 12, 1602—depicts the defeat of Baz Bahadur of Malwa by the Mughal troops, 1561. The Mughals extensively improved metal weapons and armor used by the armies of India. Hyder Ali (c. 1722-1782)—the ruler of the Kingdom of Mysore till 1782—developed military rockets using metal cylinders to contain the combustion powder.

Fairhurst (1918) helped initiate what would later become IISCO. History of metallurgy in the Indian subcontinent began during the 2nd millennium BCE and continued well into the British Raj.[1] The Indian cultural and commercial contacts with the Near East and the Greco-Roman world enabled an exchange of metallurgic sciences.[2] With the advent of the Perso-Mongols, India's Mughal Empire (established: April 21, 1526—ended: September 21, 1857) further improved the established tradition of metallurgy and metal working in India.[3] The cautious approach of the British Raj led to stagnation of metallurgy in India as the British regulated mining and metallurgy—used in India previously by its rulers to build armies and resist England during various wars.[4]
[edit] Early History (—200 CE)Recent excavations in Middle Ganga Valley conducted by archaeologist Rakesh Tewari show iron working in India may have begun as early as 1800 BC.[5] Archaeological sites in India, such as Malhar, Dadupur, Raja Nala Ka Tila and Lahuradewa in the state of Uttar Pradesh show iron implements in the period between 1800 BCE-1200 BCE.[5] Sahi (1979: 366) concluded that by the early 13th century BCE, iron smelting was definitely practiced on a bigger scale in India, suggesting that the date the technology's early period may well be placed as early as the 16th century BCE.[5] Some of the early iron objects found in India are dated to 1400 BCE by employing the method of radio carbon dating.[6] Spikes, knives, daggers, arrow-heads, bowls, spoons, saucepans, axes, chisels, tongs, door fittings etc. ranging from 600 BCE—200 BCE have been discovered from several archaeological sites.[6] In Southern India (present day Mysore) iron appeared as early as 11th century BCE—12th century BCE.[7] These developments were too early for any significant close contact with the northwest of the country.[7] The earliest available Bronze age swords of copper discovered from the Harappan sites date back to 2300 BCE.[8] Swords have been recovered in archaeological findings throughout the Ganges-Jamuna Doab region of India, consisting of bronze but more commonly copper.[8] Diverse specimens have been discovered in Fatehgarh, where there are several varieties of hilt.[8] These swords have been variously dated to periods between 1700-1400 BCE, but were probably used more extensively during the opening centuries of the 1st millennium BCE.[8] The beginning of the 1st millennium BCE saw extensive developments in iron metallurgy in India.[7] Technological advancement and mastery of iron metallurgy was achieved during this period of peaceful settlements.[7] The years between 322—185 BCE saw several advancements being made to the technology involved in metallurgy during the politically stable Maurya period (322—185 BCE).[9] Greek historian Herodotus (431—425 BCE) wrote the first western account of the use of iron in India.[6] Perhaps as early as 300 BCE—although certainly by 200 CE—high quality steel was being produced in southern India also by what Europeans would later call the crucible technique.[10] In this system, high-purity wrought iron, charcoal, and glass were mixed in a crucible and heated until the iron melted and absorbed the carbon.[10] The first crucible steel was the wootz steel that originated in India before the beginning of the common era.[11] Archaeological evidence suggests that this manufacturing process was already in existence in South India well before the Christian era.[12][13] Wootz originated in India before the beginning of the common era.[11] Wootz steel was widely exported and traded throughout ancient Europe, China, the Arab world, and became particularly famous in the Middle East, where it became known as Damascus steel. Archaeological evidence suggests that this manufacturing process was already in existence in South India well before the Christian era.[12][13] Zinc mines of Zawar, near Udaipur, Rajasthan, were active during 400 BC.[14] There are references of medicinal uses of zinc in the Charaka Samhita (300 BC).[14] The Rasaratna Samuccaya (800 AD) explains the existence of two types of ores for zinc metal, one of which is ideal for metal extraction while the other is used for medicinal purpose.[14] The Periplus Maris Erythraei mentions weapons of Indian iron and steel being exported from India to Greece.[15] [edit] Early Common Era—Early Modern EraThe world's first iron pillar was the Iron pillar of Delhi—erected at the times of Chandragupta II Vikramaditya (375–413).[16] The swords manufactured in Indian workshops find written mention in the works of Muhammad al-Idrisi (flourished 1154).[17] Indian Blades made of Damascus steel found their way into Persia.[15] European scholars—during the 14th century—studied Indian casting and metallurgy technology.[18] Indian metallurgy under the Mughal emperor Akbar (reign: 1556-1605) produced excellent small firearms.[19] Gommans (2002) holds that Mughal handguns were stronger and more accurate than their European counterparts.[20] Srivastava & Alam (2008) comment on Indian coinage of the Mughal Empire (established: April 21, 1526 - ended: September 21, 1857) during Akbar's regime:[21]
Statues of Nataraja and Vishnu were cast during the reign of the imperial Chola dynasty (200-1279) in the 9th century.[18] The casting could involve a mixture of five metals: copper, zinc, tin, gold, and silver.[18] Considered one of the most remarkable feats in metallurgy, the Seamless celestial globe was invented in Kashmir by Ali Kashmiri ibn Luqman in 998 AH (1589-90 CE), and twenty other such globes were later produced in Lahore and Kashmir during the Mughal Empire.[22] Before they were rediscovered in the 1980s, it was believed by modern metallurgists to be technically impossible to produce metal globes without any seams, even with modern technology.[22] These Mughal metallurgists pioneered the method of lost-wax casting in order to produce these globes.[22] [edit] Colonial British Era—Republic of IndiaIn the The New Cambridge History of India: Science, Technology and Medicine in Colonial India, scholar David Arnold examines the effect of the British Raj in Indian mining and metallurgy:[4]
The first iron-cased and metal-cylinder rockets were developed by Tipu Sultan, ruler of the South Indian Kingdom of Mysore, and his father Hyder Ali, in the 1780s.[23] He successfully used these iron-cased rockets against the larger forces of the British East India Company during the Anglo-Mysore Wars.[23] [edit] Notes
