Clay Block is used to make hardened clay, and it is a better way to store the clay. You just need Raw Clay to make a Clay Block. Please follow the following steps to make Clay Block.
In order to make a clay block, the basic item you need is Raw clay. You will have to find and get at least 4 clays. You will find them under the water. Use your stone shovel to gather the clays.
After that you can craft clay blocks from Raw clays you have collected. Head towards the crafting table and add 4 raw clays in any four adjacent cells of 3*3 crafting grid. You will get a clay block in the right-side box of the crafting table. Add this clay block into your “ready to use” stock.
