Interest Check (Coal)

I’m rebuilding my lab at the moment, and I used to run a service for people where they would give me a smart stack of coal, I would compress it into the compressed variety for them and keep the few loose coal that’s extra. Would anyone be interested in me starting this service up again?

It amounts to 900 Coal --> 100 Compressed.

Welche art von kohle. Weich, mittel, hart?
Oder ist das egal.

It doesn’t matter. It’s basically the same recipe for all types.
