After waiting for a long time, there was finally the sound of boiling in the reaction kettle.
Lavoisier just watched the technicians busy at work—he had already guided them through the production process repeatedly—and explained to the Crown Prince:
"Soon the solution will be distilled and then pumped into another reaction kettle to begin cooling and precipitating.
"Of course, there are other impurities in the product, but they only need simple treatment."
He then pointed to the discharge outlet, where three workers were packing the damp, light yellow powder into burlap sacks.
"After drying, you can obtain potassium fertilizer with a purity of more than 97%. Currently, this factory can produce about 100 bags a day, which is 5 tons, if the raw materials are sufficient."
"You have done very well." Joseph nodded appreciatively, then asked, "So, if we want to increase production capacity a hundredfold, how long do you think that would take?"
