I had a chance to try this finish on a mirror my mom had. This mirror is one of the first pieces of furniture she bought after she and my dad got married and it is one of the only ones she has held onto. Needless to say, it was still in its original finish some 42 years later!
She bought a new console table for her entry way last year and wanted this mirror to match.
I brought it home and spread the Elmers glue all on the frame.
After waiting til it was tacky, I painted over it with black paint.
That is better, now you can see it.
Here is a close up of the console table. You can see why we went with the crackle look.
