Ash is a valuable resource in Infinite Craft as it can be used to create various items, including potions, dyes, and building blocks. To make ash, you will need to burn wood or other organic materials in a furnace or campfire. The resulting ash can then be collected and used for various purposes.
Ash is particularly useful for creating potions. For example, a potion of healing can be created by combining ash with water and glowstone. Ash can also be used to create dyes, such as black dye, which can be used to color clothing or other items. Additionally, ash can be used to create building blocks, such as ash bricks, which are more durable than cobblestone.
