Wait, cinnabar doesn’t need to be changed, otherwise it will damage the mercury bath production line.
In reality, cinnabar is directly heated and decomposed into sulfur and mercury under the condition of air isolation. When oxygen is added, sulfur dioxide and Mercury will be generated. Since mercury is liquid, it is difficult to add recipe in the roasting oven. This may be the reason why cinnabar has not been roasted so far.
As for powellite and wulfenite, I don’t know what the real prototype is? Do you have relevant information?
