Glazed Terracotta is a new type of Minecraft block added on June 7, 2017 as part of the “World of Color” update (1.12). The blocks come in 16 different vibrant patterns and are primarily used for decoration purposes. Crafting glazed terracotta is simple, just smelt a block of stained terracotta in a furnance. You will get the same color of terracotta back, but in the glazed form.
In the photo above, you can see the main patterns and designs that can be made. Note that the direction you are facing when you place the block will rotate the block. To create these patterns, you will have to experiment with the placement in different directions. There are more potential patterns than what is shown below, however these are the primary patterns.
Tip: The easiest way to find plain terracotta is by mining it in Mesa biomes. You can then stain plain terracotta to any color using dye in a crafting grid.
Glazed terracotta is primarily used as a decoration for flooring or walls. Because of the vibrant patterns, it’s important not to over-do it or else your build will look tacky. I recommend using it sparingly, for example as a centrepiece for your wall or floor.
You can also combine different textures together to create a beautiful mural. For example, the below pattern was created by a reddit user:

They are the same thing. Hardened clay was renamed to terracotta in a previous update.
