Poor Results From Gold-ish Leaf (Dutch Guilding)
Did a quick experiment with some Dutch Guilding leaf to see just how conductive it is. I put some nail gel on a slide, placed a sheet of paper on top, and used a cylindrical burnisher to rub it down. The idea being to form a thin layer of resin, which I then set to hold the guilding in place. Looks nice and shiny:
Zoom in with the microscope and we see why:
I need gold. Gooooold!!!

How about silver? I am currently conducting some experiments with this stuff:

I have found it to be extremely conductive and a pretty good epoxy as well. A bit thick and gummy when it comes out of the tubes but I mix it with Isopropyl alcohol to thin it down into a smooth syrup. This mix spreads out really thin and dries quickly.
I bet it would work with your existing dip probe setup. Either setup a mix and use it combined - the hardening time is about 20 min depending on the temperature. Or possibly use two pools - one with part A and one with part B and drop in on top of one another. Being epoxy, if the pools do not mix they stay liquid indefinitely and do not harden.
The big downside is that the stuff, being silver, is stupid expensive. But for the things we are doing one does not need all that much and a tube will last a long time.
