Ice Cauldrons

I think that it would be cool if you could put crushed ice into a cauldron. Whether it be by putting ice on a cauldron and dropping an anvil on it, right-clicking the cauldron with ice, or getting a bucket of ice! Maybe the ice cauldron could be used for brewing things with a bottle of ice-water. Maybe crafting the opposite of fire-resistance... frostbite resistance! Going into cold oceans or snowy water might hurt you slowly, making it a must-have for adventuring out. Not only that but you could craft an arrow of frostbite using crushed ice. I find this a really cool concept that should be added in the snowy mountains update. (Or just any update in general!) I personally freaked out when I thought of this and thought it was the best idea ever. I don't know, maybe that's because I cant come up with anything ever. Let me know what you think! If you like it, give it a vote!
