Pour vinegar on ornament ?
Here is a link to an article on making Mercury Glass Ornaments... I hope this helps!
Here's a tutorial for making glass ornaments that look like mercury glass. You can't make actual mercury glass anymore.
I just saw a tutorial , they said to put a couple of drops of vinegar in the clear glass ornament , then a quick spray ( inside ) of copper and mirror spray paint . Then aim a blow dryer into the opening while spinning the ornament to spread the paint around inside . The blow dryer will dry the paint quickly .
