"The process of coke formation releases ammonia gas, which can be used to make important fertilizers, but it requires acid for absorption,"

The Head Warrior looked toward the corner at the "acid" section, where below were written "hydrochloric acid," "sulfuric acid," and "nitric acid." He recognized each word, but together, they were entirely confusing.

"The easiest acid to obtain is sulfuric acid. If you find sulfates, like green vitriol or gall vitriol, just use ceramic pots for dry distillation. If you can't find those, you can also use the lead chamber process. We already have sulfur and saltpetre, the combustion of the two produces a mixture of gases, which, through a corrosion-resistant lead chamber, oxidizes to form sulfuric acid... Well, that should roughly be the principle. There are also lead-zinc ores here, making lead quite easy to produce. If you don't care about purity and efficiency, you could try making some with primitive methods..."
