“火石红”的真伪是鉴定古陶瓷真伪的重要依据之一。有关“火石红”的论述和文章很多,总体来说有两种观点:1.“火石红”是出窑前降温时胎釉中含铁的氧化物二次氧化所生成的,也就是说“火石红”是“天生”的。2.“火石红”是出窑后胎釉中铁的氧化物在常温常压下经过长期风化所生成的,也就是说“火石红”是“后生”的。 “Flint red ” authenticity is one of the important basis for authenticity of ancient ceramics. There are two kinds of opinions and articles about “Flint Red ”. Generally speaking, there are two kinds of views: 1. “Flint Red” is generated by the secondary oxidation of iron-containing oxide in the tire glaze before the kiln is cooled down, In other words, “Flint red” is “born ”. 2. “Flint red ” is out of the kiln after the glaze iron oxide at room temperature and pressure generated by long-term weathering, that is to say “Flint red ” is “afterlife ”.
