Fortunately, it seemed that Anna was still calm, Roland discovered in relief, “Even though an enhanced witch is not affected by the God’s Stone of Retaliation, she still has to fight with their own body. Comparing this with the quick fire of hot weapons, the limitations of the body will always be too big in comparison, I think the odds that we win is at least around 70 %.”
Roland had already corrected designs for the Revolver’s bullet a long time ago. After all, circular lead bullets and loose gunpowder were an arrangement that was simply too archaic. Taking Anna’s processing capacity into account, it should be feasible for her to directly manufacture the shell for the ammunition. The problem was that there didn’t exist a reliable primer, which could light the cartridge of the bullet that was filled with black powder.
The outer shell of the ammunition was generally made out of mercury fulminate which was very sensitive to impacts. When the firing pin was pulled and it hit the base of the bullet, the mercury fulminate would ignite, which would ignite the black powder, ejecting the bullet from the chamber.
It was such a pity that even after breaking his head over it, he still couldn’t recall the necessary raw materials he needed for the mercury fulminate. From a literal point of view, he would definitely need nitric acid and mercury. However, if he looked at the result of the chemical equation he had written down, it became apparent that these two substances would only produce nitric acid together.
In addition, knowing the raw materials wasn’t equally to having a smooth production of usable products. Roland would still have to discover the right concentration and temperature for the reactive process, and whether he still needed to add another catalyst or not add one, was also a crucial point he had to figure out before finishing the product.
Moreover, because of the sensitive properties of mercury, manufacturing it was considered a very dangerous process and if it exploded one could easily lose some fingers, so Roland was afraid of trying it out personally.
So, Roland had to settle for the second-best option, using a metal ammunition case but keeping the old flintlock ignition, which would require that the spark could enter the interior of the ammunition case to ignite the gunpowder. Therefore, he had to leave a hole at the bottom of the ammunition case, but he still had to find a method which would prevent leakage of black powder.
Obviously, these two points were contradictory to each other: the greater the opening, the faster the leakage of gunpowder. Yet if the opening is too small, it would become too difficult for the spark to ignite the gunpowder.
He needed something that would allow the spark to ignite the powder, while at the same time blocking the hole, to prevent the leakage of gunpowder.
Roland first thought was pyroxylin, which was also known as nitrocellulose.
It was also one of the few chemicals which he still remembered and could also be used for weapons because it had such a simple production method: the cotton had just to be soaked in two strong kinds of acids. The two acids it used were the commonly available sulfuric acid and nitric acid, and there would be no danger involved in producing them. Even though he still had wanted to wait for the hopefully soon, arriving alchemist, but now, where he had the deadline of seven days, he decided to roll up his sleeves and get to work.
Taking the quill, Roland began to write down the idea he had already in his head for a long time.
The first ingredient he needed was cotton, and the best cotton yarn were the ones which weren’t weaved or dyed and it was exactly this kind that he had brought back with him from his visit to the Duke’s castle, and was now also piling up within his castle’s warehouses. Cotton yarn needed to be skimmed. Otherwise the grease attached to its surface would prevent the nitrification.
He was already familiar with the stuff required for removing the oil, it was sodium hydroxide, which was also commonly known as caustic soda. At the same time, it was also one of the raw materials needed for making soap: For producing soap, one had to add fat to caustic soda, and then stir it until it became solid. Afterward it could be used as washing soap. But Roland has been too busy developing the industrial and agricultural technology and with defending Border Town against foreign enemies, that he hadn’t found any time to invent any such commodities.
As for how he was meant to produce caustic soda, the simplest method would probably be the electrolysis of salt water. So the Prince discovered, that in order to create the new types of bullets, he first had to develop a DC Generator.
