Quartz slab is one of the craftable blocks in the Minecraft game and you can use it for decoration.
To make a Quartz Slab, you will need to go into Nether to get Nether Quartz then have to make Quartz Block. Please follow the following steps to make a Quartz Slab.
In order to make quartz slab, the basic item you will need is nether quartz. So you will need to go to nether to find and get at least 12 nether quartz by using your iron pickaxe.
Then exit the nether and make your way to the crafting table. Add 12 nether quartz on 3*3 crafting grid to make 3 blocks of quartz as 4 nether quartz will make 1 block of quartz. Use 3*3 crafting grid in the same way as shown in the image below. You will get blocks of quartz on the right-side of the crafting table. Bring these blocks of quartz in your inventory.
Now you will be able to make a quartz slab by using the crafting table. Add three quartz blocks in any row of 3*3 crafting grid to craft six slabs. You will get 6 slabs in the right-side box of the crafting table. Add these slabs in your “ready to use” stock.
