If we want to bake the pizza with the cheese on it, I always recommend good melters.

如果我们想烤带奶酪的披萨，我总是推荐容易融化的奶酪。

The same is true of glass melters.

玻璃熔炉也是如此。

The glass industry vows to build hybrid melters, to be heated by a mix of electricity, gas and, one day, green hydrogen.

玻璃行业发誓要建造混合熔炉，用电、气和有朝一日的绿色氢气混合加热。
