Hey guys, I am back with another suggestion. Without wasting another second, Let's get on the topic.
You can put only water in it, ever thought of filling it with other liquids? Here is my suggestion.
Colored Water in Cauldrons
Leather Armor coloring will be changed. Instead of using a crafting table for it, you first put water in a cauldron and then dye it with dyes. Right clicking a piece of leather armor on the cauldron will dye it. When you try to pick up it in a bucket, you get normal water back. Feature already in Pocket Edition.
Potions in Cauldrons
Ever wanted to store potions in a cauldron? Well, now you can. It takes 3 bottles to fill the cauldron. You can store any potion, but you cannot mIx them. When attempting to mix the potions (or potions with colored water) clears the cauldrons and displays explosion particles. The cauldron which generate in the witch huts will generate with potions of instant healing, poison or weakness. Feature already in Pocket Edition.
Tipping arrows in Cauldrons
Tipped arrows can be made using right clicking arrows in a cauldron filled with potion, I guess this could be another way to obtain them but as the liquid in the cauldron goes down, the lingering potion method would be better. I still suggest this. Feature already in Pocket Edition.
More liquids in Cauldrons
Cauldrons will be able to be filled with Lava and Milk. When you fill it with milk or lava, it will work just like water. You can take them out when needed.
Mixing two different types of liquid will cause the cauldron to empty and explosion particles will be displayed. Filling any liquid in a cauldron will require filling it thrice like water.
Stews in Cauldrons
Filling cauldrons with stew for decoration was what I wanted the last time I made a campsite. This can be used for storage or aesthetically. The appearances are as follows:
1. Mushroom Stew: Pale peach-like color like the one seen in the bowl with a few bits of mushroom faintly visible.
2. Rabbit Stew. Same color like seen in the bowl with bits of rabbit feet.
3. Beetroot Soup: Maroon-Purple Soup with tiny bits of chopped beet visibled
This is great. Adding more uses to a cauldron is definitely better. I just don't like that using potions on cauldrons would make tipped arrows though because that would make the tipped arrow recipe which uses lingering potions useless.
I realy like idea of useing cauldrons to dye items. In the sence of filling cauldron with water. Then adding the dye to change the water's color. Then place in item to be dyed.
I also think one bucket should fill the cauldron. And one bucket equals three bottuls or bowls. In size of liquid it makes sense.
Now on to soup and stews. I think the cauldron should be MAKING all of the soups and stews in the game. Not the crafting tabul. This would be a very good use for the cauldron. To be the kitchen of sorts. And it would make higher teir foods more base or camp bound. And could extend the cooking / foodstuff in game. So how to implement / use : Cauldron should be placed over fire and filled with water. Water boiling could be added? Then drop in needed itums to make. Like 6 mushrooms would make mushroom soup. Which can be taken out of cauldron by right click with 3 bowls.
