I think it would make sense to have a simple vanilla mechanic for freezing water into ice. This would make ice a renewable resource, which could be useful if you need to get large amounts of ice. Currently, the only renewable way to get resources for a snow biome is to fight the frost legion, which is not only extremely slow but requires you to be in later hardmode. I think it's actually weird that this isn't already a mechanic, considering the ice machine crafting station explicitly shows the animation of water being frozen into ice. The way it works would be pretty simple - placing water on an ice machine will make the water dissappear and pop out as an ice block item. It would be similar to how an extractinator works. As for melting ice it would be a simple crafting recipe - ice + bucket at a furnace = water bucket
