Ceramics is pottery done with a specific material. 'Slip' is poured into a mold and later removed from that mold when it has dried enough to hold its shape. At this stage a ceramic item is called "greenware." At some point the ceramic item needs to be fired in a kiln to be completed.

ceramic 主要指陶瓷材料及制品 比如SiC陶瓷 氧化铝陶瓷等； pottery 一般指陶瓷制品，偏古典陶瓷品 盘子 碗 瓶等。你想pot是什么pottery就是和它一类的东西
