Thanks to Teresa at Homemade Iowa Life, the project for 1/11 is Instant Antique Glass, page 48 of January Martha Stewart Living. If you don’t have the magazine, you need some kind of glass vase, or votive holder, etc, a spray bottle with water and mirror paint in a spray bottle.
You need to work in a ventilated area. Clean the glass and cover the outside with paper. Spray the inside with water then the mirror paint. Turn it upside down on a drying rack so air can circulate and let it dry completely overnight. You can repeat if necessary. The result should look like mercury glass.
I love mercury glass, so I can’t wait to see how this turns out.
