青花的起源,学术界有过多次的探讨。青花的矿物化学成分在许多釉类中都存在,而青花与蓝釉或其它彩釉类之区别,仅在于是单色釉下彩还是混合釉产生。如果将青蓝色或含有钴料釉都说作青花,那么就得追溯到汉朝。青花料在瓷胎上烧制,实际上不罩上表釉(透明釉)则不会出现青蓝色的效果。就算罩上表釉,不同胎质和火候所产生的色彩也不同。同一种釉可产生多种颜色。在肯定元青花的同时,也开始了对唐青花的探索。由于人们公认的唐青花实物太少,只是在扬州出土的青花碗碎片上作了些文章,未能有更多的资料可供研讨。目前的有关资料,我们可以公认青花瓷早在唐代已烧成,国外的实物和国内出土资料的佐证,此说成立无疑。从已发表的青花瓷图片看,青花色
The origin of blue and white, the academic community has had many discussions. Blue mineral chemical composition exists in many glaze classes, and blue and blue glaze or other color glaze only difference is that monochrome underglaze or mixed glaze produced. If the cyan or cobalt material glaze is said to be blue and white, then you have to go back to the Han Dynasty. Blue and white porcelain firing on the tire, in fact, not covered on the table glaze (transparent glaze) is not cyan blue effect. Even if the cover on the table glaze, different tires and the heat generated by the color is also different. The same type of glaze can produce a variety of colors. Affirmed yuan blue and white at the same time, also began to explore the blue and white flowers. Due to the fact that there are too few people in the world to recognize the Tang blue and white flowers, some articles were made on the fragments of the blue-and-white bowl unearthed in Yangzhou and no further information was available for discussion. The current relevant information, we can recognize the blue-and-white porcelain as early as the Tang Dynasty has been burned, foreign physical and domestic evidence of the unearthed evidence, this is no doubt established. From published blue and white porcelain picture, blue and white color
