We are trying to avoid water base gelatin, adhesives that will leave surface residue like epoxies, or viscous fluids that prevent even layer adhesion.
I tried a thin layer of cyanoacrylate glue on a clean dry glass surface, but humidity in the air likely caused the porous surface of the thin gold foil to solidify the escaping gaseous form of the glue into a useless frosting.
Anyone have tips for a technique to bond this foil hygienically without losing the exposed conductive surface?
Where do you get/make gold foil? I need some gold foil to use it as target (source) in my sputtering experiments, since a gold coin will be prohibitively expensive for me.

Making conductive glass with Tin Chloride is more common: note, making Tin Chloride from solder near an open flame is not safe (Stannous Chloride is only $6 on ebay):
Traditionally, some people just directly flame heat a clean slide with a SnO solution to form a temporary conductive layer.
Pure gold foils are available as eatable food grade 24k gold-leaf. It is the cheapest source if uniform thickness/quality is not a requirement. Typically, apparatus structure yields can be low due to the delicate nature of handling the foils.
