A Powder Snow Cauldron forms when a player empties a Powder Snow Bucket into an empty Cauldron, or when a Cauldron sits in a snowy biome during snowfall and slowly accumulates powder snow. Powder Snow Cauldron stores up to 3 layers in Java Edition or 6 layers in Bedrock Edition, and a Powder Snow Bucket emptied into an empty Cauldron fills every layer at once; a partially filled cauldron cannot be topped up with a bucket. Powder Snow Cauldron carries hardness 2 and blast resistance 2, and a wooden pickaxe or better is required to recover the block as an item; mining without a pickaxe drops nothing.

Unlike a Powder Snow block, a Powder Snow Cauldron deals no freeze damage to entities that stand inside, so decorative snow storage stays safe for wandering villagers and players. A Powder Snow Cauldron still extinguishes burning mobs and players on contact, though every extinguished entity drains one layer and a full cauldron becomes a Water Cauldron one water level lower, while fall damage passes through unaffected. Powder Snow Cauldron is renewable (you can farm it endlessly via snowfall in snowy biomes) and was introduced in Minecraft Java Edition 1.17 and Bedrock Edition 1.17.0.
