As near as I can tell the the only thing that can form a clear solid
of any dimension in one (sorta) step is acrylic.

Glass actually solidifies green in thickness from much of what I read,
and epoxy cures yellow.

Did you look at System Three products ?

Specifically the "Clear Coat" and the "Mirror Coat" at:

I've not done deep potting with them but have done some around 1/2" with no
problem.
