In a room in the great hall adapted as a small laboratory, Einar was proudly staring at the glycerin he had made using sugar obtained from beets.
Along with some vinegar, although it was natural glycerin, it worked perfectly to demonstrate to captive Vikings, as it was combined with alcohol to form a very primitive antibacterial gel.
But this was only the beginning, as Einar had managed to create sulfuric acid a few weeks ago, which is a strategic material that is easy to produce.
The only thing he did was burn sulfur in a container until it was consumed, due to the danger from the smoke.
This had been done abroad, and by slaves who had received training from Einar.
After the sulfur was completely consumed, the slaves emptied it into a large glass container that had a small platform so that the black sulfur would remain in that place.
