阅读《鲁滨孙漂流记》片段，回答问题。

　　于是我开始研究怎样支配我的火力，替我烧几只罐子。我不知道怎样去搭一个窑，像那些陶器工人烧陶器用的那种窑；我也不知道怎样用铅去涂釉，虽然我还有一点铅可以利用我只把三只大泥锅和两三只泥罐一个搭一个地堆起来，四面架上木柴，木柴底下放上一大堆炭火，然后从四面和顶上点起火来，一直烧到里面的罐子红透为止，而且当心不让它们炸裂。我看见它们已经红透之后，又继续让它们保留五六个小时的热度，到了后来，我看见其中有一只，虽然没有裂，已经熔化了，因为我搀在陶土里的沙土已经被过大的热力烧熔了，假如再烧下去，就要成为玻璃了。于是我慢慢熄灭火，让那些罐子的红色逐渐退下去，而且整夜地守着它，不让火退得太快。到了第二天早晨，我便烧出了三只很好的瓦锅和两只瓦罐，虽然不能说美观，却烧得再硬也没有了，而且其中的一只由于沙土烧熔了，有一层很好的釉。　　

　　经过这次试验成功之后，不用说，我不缺什么陶器用了。但是我必须说，讲到它们的形状，却很不像样，这是任何人都想得到的，因为我实在没有别的办法，只有像小孩们做泥饼，或是像一个不会和面粉的女人做馅饼那样去做。

　　当我发现我已经制成了一只能耐火的罐子的时候，我对于这件微不足道的事情所感到的快乐，真是无可比拟。我来不及等它们完全冷透，便把其中的一只放到火上，倒进一点水去，煮了一点肉；结果成绩非常好。我用一块小山羊肉，煮了一碗很好的肉汤，虽然我没有燕麦粉和一些别的配料把它做得合于我的理想。
