After waiting for a long time, there was finally the sound of boiling inside the reactor vessel.
Lavoisier simply watched the technicians as they worked—the manufacturing process had already been repeatedly instructed by him—and he explained to the Crown Prince:
"Soon, distillation of the solution will begin, and afterwards it will be pumped into another reactor vessel to start cooling and precipitation.
"Of course, there will still be other impurities in the product, but they only require simple processing."
He then pointed at the discharge outlet, where three workers were loading damp, pale yellow powder into burlap sacks.
"After it is dried, we'll get potassium fertilizer with a purity of over 97%. At present, this factory can produce about 100 sacks per day, which is roughly 5 tons—assuming there are sufficient raw materials."
