How do I color glass with glue and food coloring?

Patrkcia....I paint clear vases, bottles, etc. by using Elmer's glue and a drop of food coloring and stir with a toothpick until I have the color I want. I use a sponge brush to paint then it appears a little streaked but mine dries very smooth and I love the pastel colors. I don't have measurements because I do small items to paint but if you use the amount of glue you think you need and make sure it is mixed well you should have no problem. Have fun...my daughter and I love doing it!

Here's someone who mixes the two ingredients right on the glass for another look. https://craftsbyamanda.com/kid-friendly-diy-stained-glass/
