Dusts are gained from macerating their respective ores. With the exception of coal, which only returns one dust per piece, all ores when macerated will give 2 dusts of their type.
Dusts (from Blocks)
|Note: Coal Dust cannot be made out of Charcoal.|
Dusts (from Ingots)
The Bronze Dust recipe is shapeless. Note: There's no way to separate the tin/copper dusts afterwards.
Dusts, apart from coal dust and glowstone dust, can be smelted into ingots, allowing for 2 ingots per ore. Dusts may also be used in a variety of recipes for machines and items.
