Tutorial:Clay and Mud farming
Farming mud and clay is very simple. Making clay requires you to soak a dirt block with a water bottle to turn it into mud, and then place it over a dripstone block which has a dripstone below it. The mud block will eventually "dry out" and turn it into clay.
This method is how to farm it from scratch if you haven't found a swamp yet and don't have any mud. If you do have a lot of mud, you can replace the dirt with the mud and you don't need to worry about soaking it. Here is what you will need and how to do it:
First, you will need to build up 4 blocks and start placing some dripstone blocks in that height. You can do it in any style you prefer, such as strips or squares. Then, place stalactite dripstones under the blocks, and place dirt above it. Then, place the water in a spot where you can access it when above the dirt blocks, and fill up all the glass bottles and soak all of the dirt with the bottles, until it turns into mud. When the chunk is loaded the mud will slowly dry out and eventually turn into clay, and then you can harvest it and repeat the process of placing and wetting the dirt. Please note that this doesn't work in the Nether.
