DIY Mercury glass mason jars. Looking glass spray paint, equal parts vinegar/water spray bottle. Spray with water mix then add light coat of spray paint. Allow to dry. Use a paper towel to wipe away bubbled areas for completed look.
Spray paint pine cones to have that mercury glass look to them. Use Krylon Looking Glass Mirror-Like Paint on pinecones, add a little fresh or faux greenery to accomplish this look.*** this link really doesn't tell you how to do this, but it's pretty self explanatory (try adding some white twinkle lights in the bowl or apothecary jar!)
