Lets talk pearl ex pigments! I love using them to make ink for calligraphy. I made a video below going through the whole process but here is the basic breakdown:
4 Parts Pearl Ex
1 Part Gum Arabic (powder)
4 parts water
One thing I did forget to mention in the video is after mixing the ink always test it on the paper stock you will be using, let it dry, and make sure it doesn't smear. If it does try adding some more gum arabic. I do this with all my inks, in my opinion it's worth the extra time. It's terrible when 35 envelopes in you realize the ink / paper stock are not interacting well and you have to start over!
Hope you liked this video and let me know how you like Pearl Ex Pigments!
