I put a glob of gel medium (about the size of a quarter) directly on my craft mat. That's only one of the reasons I love that mat. Nothing really sticks to it, and just about anything can be cleaned off of it.
Then I added 1 drop of reinker. The distress reinkers come in a glass bottle with an eye dropper cap, so measuring drops is easy. If you try this with another brand of reinker you'll have to find another way to measure drops.
I mixed the two well, and it looked like I'd have good coverage.
When I painted it on the page of text I could barely see the blue, even though it looked fairly dark when I was stirring it up. So I tried again with 2 drops....still kind of light....and finally, 4 drops. Here are my results:
If you want a very pale color, 1-2 drops should do the trick. For a deeper color, I'd say at least 3 or 4, but if that's not deep enough for you, just add one more drop at a time until you have the depth of color you want.
Also, remember, reinkers from other companies might be more or less intense, so your results could be different.
But it's nice to know we have more than one way to create a glaze.
I hope this has been helpful.
