Burn wood thoroughly to create carbon black ashes. The wood must be burned completely to achieve this chemical reaction. Collecting the ash from fully burned fireplace wood will suffice.
Pour enough vodka into the ash to form a thin, slurry mixture. Mix the compound in a blender for up to an hour until the desired consistency is reached. Some mixtures are ready within only 15 minutes of blending, while others take longer.
Pour in more vodka if the ink proves to be too thick, or add additional carbon ash to thicken the liquid if it's too thin. Experiment with the ink until it's the right consistency for use.
Pour any unused ink into an airtight container for later use. Keep the ink away from sunlight to preserve it well.
