DIY Antique Mercury Glass Mirror

Before - 9 pane window from a salvage store. 

After - I used Krylon's "Looking Glass" spray paint, a spray
water bottle, and a little black & bronze spray paint for
shadowing. There are several tutorials online for this technique. 

After - Close-up view of one of the panes. The spray paint
 is surprisingly reflective and mirror-like when dry.
