翻译:建盏有毒吗?

肯定不是,但我不知道“廉价建盏”到底有没有毒。首先,我们要了解建盏的原材料。

建盏釉的制作原料非常简单,基本由釉矿物和草木灰两大类组成,其他原料还有石英、长石、石灰石等。

陶瓷釉由釉基、着色剂、熔剂三部分组成。

  1. 釉坯以石英为基底,釉矿物为着色剂,草木灰为助熔剂。

釉基石英:其实就是具有玻璃质感的成分,大概是类似石英的东西,也就是二氧化硅。

釉中矿物呈色剂:呈色剂中的化学成分决定了瓷器的颜色。例如,蓝色用氧化钴呈现,绿色用氧化铜呈现,红褐色用氧化铁呈现,是建盏的主要呈色剂。

釉料所用的矿物来源于建阳南山,这种矿物是建盏釉中最重要的呈色剂,是决定建盏能否形成花纹的最关键因素。

含铁量较高的石灰釉即为建窑黑釉,属铁结晶釉。

那么,什么是结晶釉?

当温度达到一定程度时,釉料就会结晶,在釉面或釉内形成美丽可见的晶花。

釉中在高温下会析出多种晶体,如建盏上出现的褐色兔毛纹、银滴纹、鹧鸪斑纹等,都是这类晶体。

红褐色的水晶花是由赤铁矿(Fe2O3 的结晶物质)构成的,磁铁矿(Fe3O4 的结晶物质)是形成银斑的结晶物质。

助熔剂:可以降低石英的熔点,节省大量燃料和时间。助熔剂材料通常为长石、草木灰或钡。

建盏黑釉是以氧化钙为熔剂的石灰釉。

关于建盏是否有毒,从重金属析出角度来看,它的熔剂物质需要1300℃左右才能析出。而沸水的最高温度是100℃,所以饮用或泡茶时无需担心铅等重金属会溶出。请放心使用。
