Each of the (iron) staples (used to pin down the cannon in position) weighs 3 catties and measures 1 ft 2 in. in length. The six cast-iron bands (for strengthening the barrel) each measures 1 ft 1 in. and weighs 3 catties. The barrel holds 100 bullets, each weighing 0.5 oz. (5 qian) and 3 oz. of (gun-)powder. [36]
Hongyipao (Chinese: 紅夷炮/紅衣炮; pinyin: hóngyípào; lit.

[1] The distinctive san yan chong, or three eyed gun, was one of the most common Ming hand cannons. Three eyed guns were usually made from cast iron or crude steel, each of the three ...
Of special note are the iron bands acting as reinforcements around the cannon—they indicated that the "Crouching Tiger Cannon" was a built-up cast-iron gun. [9] The iron bands were shrunk onto the barrel while red hot, and the consistently fitting bands show that the Ming Chinese foundrymen had mastered quenching in mass-production conditions ...
It is composed of a cast-iron casing, iron pellets coated in tung oil, urine, sal ammoniac, feces, and scallion juice. In the middle is a gunpowder stick. Stoneware bombs, known in Japanese as Tetsuhau (iron bomb), or in Chinese as Zhentianlei ( thunder crash bomb ), excavated from the Takashima shipwreck, October 2011, dated to the Mongol ...

If iron ores are heated with carbon to 1420–1470 K, a molten liquid is formed, an alloy of about 96.5% iron and 3.5% carbon. This product is strong, can be cast into intricate shapes, but is too brittle to be worked, unless the product is decarburized to remove most of the carbon. The vast majority of Chinese iron manufacture, from the late ...
The Chinese were also the first to master cast-iron cannon barrels, and used the technology to make the earliest infantry firearms — the hand cannons. Early European guns were made of wrought iron, usually with several strengthening bands of the metal wrapped around circular wrought iron rings and then welded into a hollow cylinder. [3]
