三彩筆記 vol.06 美國辛辛那提藝術博物館：唐三彩藍釉馬 - Cincinati Art Museum, Tang Sancai Blue Glaze Horse.

在三彩（三色）器的彩色鉛釉中，藍色是最顯著和珍貴的。來自波斯（伊朗、阿富汗）的進口鈷料被用作釉料的著色劑，產生豐富、絢麗的藍色。在唐時代，這種原材料的價格往往是黃金的數十倍，因此，三彩中的藍彩也是極為罕見、珍貴的，通常僅限於皇家、貴族使用。

In the colorful lead glazes of Sancai (Three-color ware), blue is the most striking and valuable hue. Imported cobalt materials from Persia (modern-day Iran and Afghanistan) were used as glaze colorants, creating rich and vibrant blue tones. During the Tang Dynasty, the cost of this raw material was often several times that of gold, making blue glaze in Sancai extremely rare and precious, typically reserved for use by royalty and the aristocracy.
