Adobe Bricks are Building-Blocks that look like they were made of pale red Bricks.
You will not need to unlock any crafting-recipe to make them. Instead, Adobe Bricks can be obtained by putting 
Mud into a Forge
with some 
Fuel to harden 1 Block of Mud into 4 Adobe Bricks each.
Adobe Bricks can either be placed as they are like any Building-Block, but can also be used as a material to craft more refined Adobe Building-Blocks.
Upon crafting/taking Adobe Bricks for the first time, the Recipe for 
Flower Pots is automatically unlocked.
You can find Mud in the Stalactite Layer underground, but also as a Lakebed and Riverbed on the Surface of any Creativerse-World.
Mud will require at least a Wood Mining Cell
to be pulled/harvested.
