陶瓦
陶瓦(Terracotta、Terra cotta 或 Terra-cotta,意大利文:“烤过的土”,[1]从拉丁语:terra cotta而来),又称粗陶、赤陶,是一种陶器,以粘土为原料,上釉或者是不上釉。[2] 器体本身为多孔设计。[3][4][5][6] 陶瓦被运用在许多器物上(最常被用在花瓶)、水道、屋瓦还有建筑工程的外部装饰,还有雕像如秦始皇兵马俑。陶瓦同时也可以指运用这个材料所做成的物品,或者是陶瓦的原色(棕色),这个范围相当大。在考古学与艺术史中,“陶瓦”通常指那些不是用陶工轮所制造的物品。

生产和特性
编辑一个适当品质好的粘土被塑造为所需的形状。干燥后,它被放置在一个窑中然后烧制。典型的烧成温度为1000℃,其中的铁含量,使得烧结体呈现出黄色、橙色、红色、粉红色、灰色或褐色。燃烧过后的陶瓦并不防水,然而若在燃烧之前将表面抛光则可以减少表面的孔,此外,釉层可以使其防水。这适合作为在热带环境中的花园或建筑的装饰,以及耐油容器,油灯,或烤箱。 大多数其他用途,会运用在餐具,卫生下水道,而在寒冷的环境,这种器具需要上釉面。陶瓦如果无裂纹,轻轻地拍击将会发出声响。某些陶瓦是从回收的陶瓦中制造的。
