Surely. How can I make gunpowder on my ship when I have no saltpeter, sulfur, or charcoal?

可不是。船上没有硝石，没有硫磺，没有木炭，您要我怎么制造火药呢？

Black charcoal, gray is saltpeter and gold is the sulfur.

黑色是木炭，灰色是硝石，金色是硫磺。

Well, they come from the three principal ingredients of gunpowder, which are sulfur, charcoal and saltpeter.

嗯，它们来自火药的三种主要成分，即硫磺、木炭和硝石。

And by the 11th century, the Chinese were writing down recipes for a mixture of saltpeter, sulfur and charcoal, that we now know as gunpowder.

到 11 世纪，中国人已经写下了硝石、硫磺和木炭混合物的配方， 我们现在称之为火药。
