Stained terracotta is a block with blast resistance and it is also used for decoration.
You’ll need Clay, Clay Blocks, Terracotta using Furnace, Cactus and Cactus Green Dye to make Green Terracotta. Please follow the following steps to make Green Terracotta.
In order to make terracotta, the basic item that you’d need is clay. You will have to find and get at least 32 clays. Clay can be found under the ocean.
After collecting the clay, you will have to craft clay blocks. Go to the crafting table and add 32 clays in four adjacent cells of 3*3 crafting grid. where each cell should contain 8 clays. You will get 8 clay blocks in the right side box of the crafting table as 4 clays can make 1 clay block. Take these blocks into your inventory.
Terracotta using Furnace
Move to the furnace just next to the crafting table. Add 8 clay blocks in the top box and coal in the lower box to get 8 terracotta as output in the right-side box to the furnace. Bring these into your inventory.
Now you will have to find a cactus and then use it in the furnace with coal to get a green dye. Head yourself towards the ocean and find cactus alongside the water stream.
Cactus Green Dye
Go back to the furnace again and add cactus in the top box and coal in the lower box. This will give you a cactus green dye in the right side box to the furnace. Add this dye in your inventory.
Now we can craft the green terracotta. Move to the crafting table once more and add cactus green dye in the center cell and Eight Terracotta blocks in all remaining Eight cells of 3*3 crafting grid as shown in image below. You will get Eight Green Terracotta blocks in the right-side box to the crafting table. Add these into your “ready to use” stock.
