Unsurprisingly, making Dragon’s blood ink is not as straightforward as all the online tutorials with the same copypasted (mis)information make it seem.
The recipe that can most easily be found online is a combination of alcohol, gum arabic and dragon’s blood resin. I put this to the test, and found success hinges on the qualities of the ingredients.
Part 1: the experiment.
First test, Polmos Spirytus rectified spirit. It’s the highest purity alcohol (95%) available to the general public in Australia. It’s also $70 per 500ml. I wasn’t willing to spend that much money on booze I’m not going to drink!
So we move down the price scale to vodka. Most vodkas are around 37% alcohol, the rest being water. Due to this high water content, the resin was reluctant to dissolve, and when it did, the drying time was prohibitively long.
My next unsuccessful experiment was with methylated spirits (denatured alchohol). Although cheap, it smells dreadful and leaves a foul smelling residue behind when used as an ink due to the additives which make it undrinkable.
Finally, success with Isopropyl alcohol (IPA). It’s only $9 per 250ml, 99.8% alcohol and evaporates quickly and cleanly. It can be found at specialty electronics stores such as Jaycar.
The gum arabic:
The purpose of gum arabic in ink is to increase the viscosity of the fluid, allowing it to grip the brush.
The problem: gum arabic isn’t soluble in alcohol. Trying to dilute it in water first and then adding it to the alcohol resulted in a stringy, goopy mess.
I couldn’t find any alcohol soluble equivalents, so I left it out.
As I covered in my last post, there are primarily two types of resin on the market. Daemonorops draco is not alcohol soluble. If mixed with alcohol, this palm draco resin may turn the alcohol a muddy brown colour, but will quickly settle to the bottom.
Dracaena cinnabari and Draceana Draco will both readily and quickly dissolve in alcohol and are suitable for creating ink.
Part 2: The recipe
What you’ll need:
- Dracaena resin. Elfhame’s Apothecary were very kind to provide me with some genuine D. cinnabari, or ‘medieval dragon’s blood’ for testing. It can be purchased here.
- Isopropyl alcohol
- A storage jar with a secure lid
- 2 beakers, open mouth jars or
- A brush or other writing implement
- Some patience
Powder the resin.
Because my mortar and pestle are quite large and the material very precious, I wrapped it up in baking paper and crushed it using the pestle alone, which minimizes wastage.
As it is quite readily soluble in alcohol, D. Cinnabari does not need to be crushed very fine.
Pour the powder into one of the open mouth containers. Add the alcohol and watch as the blood red colour instantly begins to seep into the liquid, quickly transforming it into a rich, black-red fluid. The process is quite captivating to watch and the resemblance to real blood is striking.
Let it settle for a couple of hours, then gently skim the alcohol off into the second container by carefully pouring it and leaving the bark chunks behind.
Due to the way in which Dracaena cinnabari is harvested, there will be a substantial amount of bark debris left.
Repeat this process until the alcohol runs relatively clear, leaving behind only spent fragments of bark.
Leave the second open mouthed container with no lid in a warm, dry place and allow the alcohol to evaporate down.
Due to the nature of the ink I didn’t find it necessary to filter it further.
Use a brush to make some test marks to gauge the correct concentration. When enough alcohol has evaporated to create the right concentration of pigment, bottle it in a sealable jar. If it becomes too thick, simply add more alcohol.
It should give a luxurious red ink, but not be too thick as to remain tacky while drying.
Note: keep alcohol on hand for cleaning brushes/writing implements, as it won’t wash off using normal methods. For this reason I recommend using a fine paintbush for writing, as they are easier to clean.
The process is a little messy, but very simple and easy. By making it yourself, you can be assured the ink is genuine. As pure Dragon’s blood ink dries scentless, this also opens up the possibilities for experimenting with adding fragrances and resins to create Bat’s blood or Dove’s blood ink and other concoctions.
