The production of ink has been practiced as a hobby for hundreds of years. Though the practice originated from a necessity to produce quality inks for personal use, many individuals continue to make their own ink for hobby or artistic purposes. Permanent ink is designed to mark on most surfaces and prevent easy removal. While there are a variety of ink types available on the market, you can prepare your own using a few common household items.
Step 1
Place the walnut hulls into an empty bag. Strike the bagged shells repeatedly with a hammer until broken into small, pebble-sized pieces.

Step 2
Place the crushed walnut hulls into a saucepan with 2 cups of water. Bring the mixture to a boil using medium heat. Allow this mixture to simmer until the water becomes dark. This will take approximately 10 to 15 minutes.
Step 3
Add the salt and vinegar to the mixture, and allow to simmer for five more minutes.
Step 4
Strain the ink into a jar using a piece of cheesecloth as a filter. Allow the ink to cool before using.
Tip
If you need to adjust the consistency of your ink, use cornstarch to thicken it or water to thin it.
Adding salt and vinegar to the mixture is what makes the ink permanent. You may leave these out for a less-permanent ink.
Warning
Be sure to wear gloves and the necessary garments to protect your clothes from being stained during the ink-producing process.
