There was a post recently about how to paint glass to look like sea glass. Possibly with Elmer’s glue as a base?

I used a spray paint that looks like sea glass. They have different colors too. https://ourcraftymom.com/create-challenge-achieve-stained-glass-look/
Krylon has a great spray paint for this. Here's a candle holder I used it on. https://acrosstheblvd.com/coastal-jar-makeover-with-sea-glass-paint/
I’ve used Mod Podge mixed with food coloring to paint glass. With this method, custom colors can be created with varying intensity. It’s applied to the glass with a sponge brush and is opaque when dry. I hope this helps!
