Chapter 166 The Night before the Final Battle

On the promised fifth day, Roland finally finished preparing all the ingredients needed to produce guncotton.

He made a serious error during the electrolysis of the salt water. He used the copper strips Anna cut out as the electrodes, causing the electrodes to dissolve. He ended up wasting an entire pot of the salt water. Saturated brine was typically used to prevent the dissolution of chlorine in water during the electrolysis process, but salt in this era was not an inexpensive, everyday item. He felt like he was uselessly throwing away gold royals when discarding the contaminated salt water. He was finally able to solve the issue after using carbon rods as the electrodes.

He boiled the caustic soda with water to remove the grease. When he ended up with grease-free cotton gauzes, he brought the rest of the caustic soda to the chemistry lab.
