What makes people most curious about this process is that the white dye must reach a temperature of 1300 ℃ before it can dye the surface of the agate, but agate is quite unstable at such high temperatures. So unless there were some means of lowering the pressure, it would have been impossible to prevent the agate from shattering.
在這個過程中，最令人好奇的是，白色染劑要在攝氏一千三百度的高溫下才能熔蝕進整顆瑪瑙中；可是在如此高溫下，瑪瑙的結構會相當不穩定，除非在溫度升降過程中做好「控壓」處理，否則瑪瑙極容易崩裂。
