Gold Ingot

Gold ingots are a metal obtained from the smelting of gold ore. It is primarily used to craft clocks, powered rails and blocks of gold. It can also be used to craft equipment such as tools and armor. Gold ingots can be crafted or found inside chests in strongholds, mineshafts, temples and villages.

Tools made from gold will mine much faster than those of diamond; however, because of gold's extremely low durability, it is typically impractical for usage in equipment, and is more often used for "showing off" rather than for its value as items/armor. Gold tools can only mine stone, cobblestone, coal, netherrack and slabs; but they dig the fastest out of all the tools, and as such may be useful if the player is in a hurry and has plenty of gold. Gold equipment also has the highest enchantability of any material in the game. However, it is a lower-middle-tier armor set and is not suggested for use as armor due to its rarity and rather low durability.
