How to Make Activated Charcoal in the Potions Master Mod

Activated Charcoal is a core reagent, and you build it from Charcoal Powder. You need a Mortar and a Pestle to break charcoal down, so craft those first if you have not already.

Grinding Charcoal Into Powder

Place a Mortar down and use the Pestle on it to process charcoal into Charcoal Powder. The Mortar is the block that holds the material, and the Pestle is the tool that does the work. Keep a steady supply of plain charcoal on hand so you can convert it whenever you need more powder.

Turning Powder Into Activated Charcoal

Once you have Charcoal Powder, process it further to reach Activated Charcoal. This is the finished reagent you will use in later potion work, so do not stop at the powder stage if your goal is Activated Charcoal itself. Store the finished Activated Charcoal somewhere dry and separate from your raw charcoal so the two do not get mixed up in your inventory.

Why You Want It

Activated Charcoal is a reagent, meaning it feeds into other recipes rather than being used on its own. Produce it in batches: grind several charcoal at once into Charcoal Powder, then convert the whole batch. That way you spend one session at the Mortar instead of returning every time a recipe calls for a single unit.
