Two days later was the day the officials from the Ministry of Works and Ye Xinyan had agreed upon to observe the smeltery workshop. Ye Xinyan, Wong Qiao, and Zhang Chang, who managed the construction affairs of Prince Yu's Mansion, went to the smeltery workshop in Huaiyuan County.
At this time, the smelting technology was quite backward. It was indeed only in the form of a workshop, rudimentary and simple, both technologically and in scale, it was far from advanced.
An experienced master craftsman from the workshop took them around, inspecting the smelting process and explaining the smelting procedure in detail, as well as the tasks required at each stage.
Sure enough, during this craftsman's narration, the key factor limiting the smelting technology and the output was the insufficient temperature.
