Eisen blew into the hot glass and slowly turned it into a bubble that he could easily turn into a proper bottle. The glass itself that Eisen was using was a special mixture as well, since it was made with a large amount of ground-up spatial gems, as well as a few other rather interesting materials. And one of those special, interesting materials was something that Eisen got his hands on after a lot of troubles.
Komer managed to acquire small amounts of Maroon here and there after spreading Starlight's influence throughout the central continent, and most of that Maroon was swiftly turned into high-grade Margon.
That Margon was obviously safely stored inside of special boxes Eisen made where nobody could steal them, and then they were placed right into Eisen's item storage as extra insurance.
