Smithing table is presented as a toolsmith's job site block that can be generated in villages. It can be used to upgrade diamond gear into netherite gear. You can get it from a village or crafting. Another black pixeled material is Netherite - a pretty rare thing from the Nether. Items made from that material are more powerful and durable than diamond, can float in lava, can't burn, and are unbreakable with an explosion. But they are still breakable - cacti can destroy them immediately. Minecraft cursor with Smithing Table and Netherite.
