wootz steel

HYDERABAD: There is archaeological evidence aplenty at the World Telugu Conference (WTC) to establish the antiquity of Telangana. Though Telangana is the youngest state in India, it has rich scientific and documentary evidence that catapults it to antiquity - one of the oldest regions in the world with ...

In Hong Kong to address the Asia Society this weekend, one of the things that strikes me again is that amid the profusion of colonial buildings in this teeming city, there is one startling absence. There is no museum to Hong Kong's colonial history. The story of Hong Kong for 156 years was the story of ...

As it cools, the Wootz steel is reheated, reshaped, and then abruptly doused with water. This quenching process, suddenly cooling the glowing hot steel with water, gave the blade a special hardness (by shrinking the crystal grain size of the material). The water used to quench the blade was referred to as ...

As we plunge forth into Industry 4.0, we discover new ways to take advantage of our existing infrastructures. Nature is often inspiration, but what's more uncommon is rediscovering lost knowledge. As we use our bones as inspiration for crack-proof metal materials, we discover that we once had already ...

Do you remember the Green Destiny sword from Crouching Tiger, Hidden Dragon. I didn't. But that damascus steel blade finished with jade is so damn gorgeous and stunningly detailed that after seeing the guys at Baltimore Knife and Sword make it, I don't think I'll ever forget it again. The whole build ...

Indian steel - also called 'crucible steel' or 'wootz steel' - was in great demand as the material with which legendary swords were forged. Foreign geographers of the 11th and 12th centuries, such as the Moroccan geographer, Ash-Sharif al-Idrisi, and the Venetian geographer, Giovanni Ramusio, were all ...

Its high carbon content of at least one percent shows it is made of wootz steel. This type of crucible steel was historically used in India and Central Asia to make high-quality swords and other prestige objects. Its band-like pattern is caused when a mixture of iron and carbon crystalizes into cementite.

At the time the Ulfberht swords were forged (approximately 800–1000 A.D.), equally perplexing swords made of a substance called Damascus steel were being produced in the Middle East out of a raw material, known as Wootz steel, from Asia. Both Damascus steel and the Ulfbehrt's so-called “crucible ...

Damascus swords – sharp enough to slice a falling piece of silk in half, strong enough to split stones without dulling – owe their legendary qualities to carbon nanotubes, says chemist and Nobel laureate Robert Curl. The blades used so-called wootz steel, smelted with a technique developed 2000 years ...

Think carbon nanotubes are new-fangled? Think again. The Crusaders felt the might of the tube when they fought against the Muslims and their distinctive, patterned Damascus blades. Sabres from Damascus, now in Syria, date back as far as 900 AD. Strong and sharp, they are made from a type of steel ...
