I’ve put together this sample of a variety of different gold leaf techniques on glass (the reverse or back of the glass). It looks much better in person (feel free to email me to schedule a consultation), but this should help you decide what type of gild you want for your business or transom (glass panel above the door). They can be put into two categories: Water Gilds/Burnished (think shiny and reflective) and oil gilds/matte (non-reflective). Please note, these are all 23 Karat Gold except the bottom right.
