How to make ink from tea
Gather materials.
For this process, you are going to need black tea, water, and a thickening agent (either gum arabic or cornstarch). Some recipes also call for vinegar, which can make your ink a bit more uniform in color.
You will also need a few measuring spoons, a metal or wooden spoon, a strainer (if using loose tea), and a ceramic bowl. Finally, if you intend to bottle your ink, you'll need a small glass bottle with a screw-top lid.
