It would be a cool mechanic if you had to mine ice with a mining drill, then heat it up before using it in water-based recipes. Maybe it could be done with a smelter, at the very least as an excuse to give it a fluid pipe graphic for modded recipes too. Would also be cool if you had to keep pipes heated or they’d burst — there aren’t many “maintenance” or “breakdown” mechanics like that, but it could risk being annoying especially if you’re on another planet.
