The glaze was mixed with metal oxides containing copper iron and cobalt, resulting in an array of different colours.

釉面与含有铜、铁和钴金属氧化物混合，产生了一系列不同颜色。

That, in turn, means a lot of cobalt, copper, lithium and nickel with which to build them.

反过来，这也意味着我们需要大量钴、铜、锂和镍来制造它们。

The recovered cobalt can be reused, meaning fresh new batteries could potentially be made from old ones.

回收钴可以重复使用，这意味着有可能用旧电池制造出新电池。

We couldn't prove where exactly the dirty cobalt enters the international supply chain but we witnessed that it does.

If you take batteries we used to use a lot of cobalt in our original lithium ion high energy batteries.

如果你拿电池来说，我们过去在最初锂离子高能电池中使用了大量钴。

They then applied a magnetic field which, thanks to cobalt's ferromagnetic nature, arranged the particles into thin columns.

然后，根据钴铁磁性，他们应用一个磁场把这些粒子“安置”到了薄薄柱子中。

Nor is it certain that cobalt mining will even be all that important in car-battery technology going forward.
