瓷銅是一種瓷器***工藝。其內部有銅器鋪墊,外表由瓷器覆蓋***而成。從原始社會的陶器演變而來,例如有名的銅紅釉,以含銅物質為著色劑,經還原焰燒成的紅色釉。用適當的還原焰煅燒,可以得到美麗的紅色,只要略有偏失,還原不完全,或部分氧化,都可能造成發灰、發綠、發黑、或燒失等現象。

瓷器的定義:

1、瓷器的胎料必須是瓷土的。瓷土的成分主要是高嶺土和化妝土,并含有長石、石英石和莫來石成分;含鐵量低。經過高溫燒成之后,胎色白,具有透明或半透明性,胎體吸水率不足1%,或不吸水。

2、瓷器的胎體必須經過1200℃~1300℃的高溫焙燒,才具備瓷器的物理性能。各地瓷土不同,燒成溫度也有差異,要以燒結為準。

3、瓷器表面所施的釉,必須是在高溫之下和瓷器一道燒成的玻璃質釉。
