Item Pots (depreciated)
With the release of Minecraft version 1.20.3, this datapack has become outdated.
This data set turns ingame pots into miniature storage containers capable of holding up to 64 units of items. To fill the container, simply drop the desired items on top of the vessel. Each decorated pot becomes a storage unit only once - you cannot put items in it again, you'll need to break it and set it up again first. However, if you drop several identical items at the same time, they will all end up inside. The items are securely stored inside until you break the ceramic vessel - then all its contents will pop out, ready for collection.
