Gold Accents?

Fun? Gold accents? This is the Krylon 18 kt gold leafing pen - applied after the glass is out of the kiln and cold.

How durable is it? Withstands casual handling - determined effort will scratch it if you really try.

Could be a fun way to add a little gold accent. Why not?  I think this is how a lot of ceramics and commercial stuff get their gold accents.
