Bellows - Bellows

Japanese: ふいご(鞴∥吹子) - ふいご
Bellows - Bellows
Humans first learned to use metals when they discovered gold dust (native gold), native copper, and meteorites. They then learned to obtain metals by burning charcoal to melt the raw ores, but this required blowing in large amounts of air to supply oxygen and raise the temperature. To do this, methods were devised using leather bags, fans, and blowpipes to blow large amounts of air at once. In Japan, the process of smelting metals has long been referred to as "blowing gold," which is probably an accurate description of the process.

Japanese:
人類は砂金(自然金),自然銅,隕鉄(いんてつ)などを見つけ,初めて金属を使うことを知った。次に炭を燃焼させて原料の鉱石を溶かし,金属を得られるようになったが,それには,送風つまり空気を多量に送って酸素を補給し,温度を上げる必要があった。そのためには,皮袋,うちわ(団扇),火吹竹などを使い,一時に多くの空気を吹きつける方法が考案された。日本では,昔から金属の製錬を〈金(かね)を吹く〉と呼びならわしているが,その実態を的確に表したものであろう。
