Clay is commonly found at the bottom of rivers, lakes, and swamps. Mine clay blocks with a shovel or fist to break them into dropping clay balls. Clay balls are the most important part of the recipe!
Next, craft a furnace. You’ll need eight cobblestone to do so.
If you have a furnace already, make sure you have enough fuel for the next step.
Place the clay ball in the top slot in the furnace GUI and fuel (such as coal or wood) in the bottom slot. With that, the furnace will smelt the clay balls into bricks!
Bricks can then be used to craft brick blocks or flowerpots!
