Recipe:Dove's Blood Ink

Use one part powdered Dragons Blood resin to an equal part Gum Arabic, which helps to give the ink a better consistency.
Slowly mix in alcohol a few drops at a time to dissolve the powders thoroughly into the correct liquid consistency to use with a pen or quill. After the mix is compete, you will add in a drop or two each of cinnamon, bay, and rose essential oils to direct the power of the ink.

Strain it through the finest grained metal strainer that you can find, or use a bit of coffee filter to get any clumps and impurities out before using the ink. Store it in a tightly closing glass bottle to keep the alcohol from evaporating and the ink from drying out.

Note: With frequent use, the ink may get thicker as the alcohol evaporates while the bottle is open.
To remedy this simply mix a sufficient amount of alcohol to get it back to the correct fluidity.
