@radiant1, I have used naval jelly (phosphoric acid) made by Loctite.
I have found by etching the electrode surface the oxides or crystals
adhere better. If it will etch it will disolve various materials including metals
into phosphate compounds.
I soaked a paper towel with the gel, got impatient, put it in the microwave
to dry it out only to find it had quickly flashed into black soot.

I experimented a little with methanol (heet) that I got at the autoparts.
In a petri dish I disolved the alum glue mix, the epsom just stood like small
rectangular blocks like stonehinge as the liquid evaporated needle like crystals formed
in the direction perpendicular to the epsom drying in a porus mycelium like fuzz.
On copper there where tiny flat pieces of epsom laying flat that repelled crystals.
the voltage was lower than thermal stovetop method.
The glue tended to lay down better and the texture was opaque.
less methanol to elmers glue ratio might adjust density as the crystals
expand. What I got could be described as hard toothpaste.
