How to get Netherite in Minecraft: from ancient debris to full gear
You get 1 Netherite Ingot; the ninth slot stays empty.

A Netherite Ingot is the strongest metal in the game, made from netherite scrap and gold.
It is made with the Crafting Table from 4 × Netherite Scrap and 4 × Gold Ingot (other recipes also exist).
With a Netherite Upgrade on a smithing table, it turns diamond gear into netherite gear that is tougher, lasts longer and survives lava. Nine ingots make a Block of Netherite, and an ingot can pay a beacon. It also serves as a trim material with a dark color.
4 × Netherite Scrap + 4 × Gold Ingot → Netherite Ingot
Block of Netherite → 9 × Netherite Ingot
