Little did I know that after promising that Hobby Lobby would promptly sell out of Krylon's Looking Glass spray paint and not have any for weeks!!!
Finally I was able to get some, yes, I bought TWO cans this time. I didn't want to take any chances!!! The vases are still drying in the garage so I will take some nicely staged shots to add to this tut when everything is dry.
This tutorial is extremely pic heavy! Beware!

Ok, let's get started. Gather your supplies.
vases (note how super clean they are):
First hold your vase by the bottom and wet your fingers. (this sounds interesting, right?) You want to 'splash' a little water inside the vases to make droplets. Some people use spray bottles, I find that using your hands makes it a little more random. You want enough water so it doesn't dry before you start painting, but not so much that it runs. If it starts to run dry it out and start over.
Vase splashed with water:
Now, go outside to your dedicated mercury glass spray paint area aka. chimney of kids' play house. This looking glass spray paint is...weird compared to other spray paints. It's really runny (watery) and smells just...strange. Wear a mask, definitely.
Hold the vase with the water droplets (again, not inside the house!) and very, very lightly spray inside the vase. It will take 5-6 coats to get the right coverage. The paint will run, that's ok, but you don't want ALL of it to run. I let them sit upside down between coats and wait about, oh, a minute or so before the next coat.
You can see how each coat just builds and builds. The reflectiveness comes through when you can start to see my phone case in the reflection ;)
After you have the coats painted let them sit upside down overnight to dry (I like to use a fancy cat litter lid in the corner of my very dirty garage):
Fast forward to the next day. The looking glass spray paint is pretty delicate inside the vases. If you aren't careful you can rub it all off. Using your soft dry rag, carefully wipe inside the vases. The goal here is to wipe off the loosened paint where the water droplets were. You can also wipe off some of the paint if you got it too thick when you were painting the layers.
Now, the vases look nice like this (but still aren't stable, will wipe off) but they just look like silver vases. One of mine was covered well with paint, the other one was not coated as well. So, I decided to use a little of the 'hammered metal' spray paint (gray) I had on hand to fill in some of the bare(ish) areas. I figured it was silverish with some black so it would work. I added a light coat to each of the vases. Much better but still not quite finished.
To make this look like real mercury glass you need it to be black inside. These vases are pretty to look at but really don't make good candle holders because they're black inside. But like I said, pretty to look at! :)
One light coat of flat black and voila! Faux mercury glass: (see the overspray on the top edge? wipes right off!)
If you want this to be super scratch resistant (because at the end of the day this is still just spray paint on glass, it can be scratched) then you should paint the inside with black gloss enamel and let it dry. It takes several days to cure completely.
If you have any questions leave me a comment or send me an email! Enjoy. Happy faux mercury glass making!
