Alchemists would have a large selection of them on their person at all times, so they can write on any material in any situation. That's actually one of the main functions of the hand cloaks. They act as both storage for various inks and as extra hands so that the more complex circuits can be completed faster. Just as an example, for a 1-hand cloak alchemist, a War Devil golem would take about 2 minutes to create, while the same alchemist would need upwards of 10-15 min for a 10m+ golem that he could control to some extent.

They are the highest rank of alchemists that achieved near impossible, and are the leaders of the country. Safe to say, even if there isn't a lot, just one appearing on a battlefield would essentially guarantee victory, specially if it's a land battle.
