Silicon is a hard glassy lustrous semiconductor, silicone is a compound of
this that's not, and can be made into sealants/...

The glass will support it just fine, as long as you don't go way
overboard,
I'd hesitate before going much beyond twice the thickness of the glass.
Ledges also can work, but if you're thinking of something thin jutting
out into the tank, silicone may be too weak to work, without support.


For full height slate ledges, I've seen them placed vertically into a frame
of concrete. Remove the frame, de-alkaline (is that a word?) and then stand
in the back of the aquarium. Generally, siliconing directly to the glass is
not a great idea unless it's a relatively permanent structure (left there
for many years).

For less permanent structure, stack in an decreasing size with sufficient
stabilizing footprint (using a U, W or T shape base). Sand is a good
substrate to fill crevices, as is a thin styrofoam sheet underneath.

Now would that be siliconing or siliconeing? ;~)
