I have read today a sentence I haven't understood, simply it doesn't have sense to me:
Ceramics can be pottery made of hardened clay.
I have looking for the meaning of pottery and ceramic and are the same: 'Cerámica', so in Spanish language, I don't know how can I give sense to the sentence. I would be glad if someone can orient me a bit.
In my poor opinion, I think it's better:
Ceramics can be made of hardened clay.
