According to the Minecraft Wiki page for the hardened clay stuff, terracotta in Minecraft has “a hardness and blast resistance comparable to stone.” That makes it an attractive material to use for building, not to mention that fact that you can color it and even glaze it, creating an even more beautiful material with which to craft opulent structures. With all the positives, and hardly anything going against it, it’s really a no-brainer to know how to craft terracotta in Minecraft and have it in your chest at the ready.
