Cauldrons are filled with water while snowing in biomes where it only snows above a certain height

That makes sense. Snow is just crystalized ice.

I knows what is snow. 0_0 But it would be both more realistic and cool if you couldn't get whater in snow areas this way.

Actually, It's very easy to melt snow. Just 0ºC.

Nvm... 🙂

Most likely also affects cauldrons in deserts and possibly cauldrons without access to the sky. Further testing required.
