En av flera förklaringar till vad det är för sorts guld:
"In the 20th century, Tomimoto Kenkichi (1886-1963), was one of these first “individual” potters of Japan. He selected overglaze enamel porcelain as his area of specialization. One of Tomimoto’s greatest contributions in the overglaze decorating field was the practice of firing gold and silver at the same temperature. Gold and silver melt differently; therefore, in order to use both on the same piece, a difficult problem arose. An additional fourth firing would have to be engineered. The gold from the third firing became tainted as it went through the cooler fourth silver firing. Tomimoto mastered a new technique by adding small amounts of gold to the silver to raise its temperature to that of gold. Then, he was able to fire both metals in one firing. He documented his discoveries, leading the way for future generations of potters to employ gold and silver on their artwork."
