and read up a bit. There is really too much information to put into a few posts. However, if it is a simple shelf, the easiest way might be...
* Clean as above.
* Bond a wooden cleat (3/4" x 1 1/2" strip the
depth of the shelf) to the wall. Do this with thickened
epoxy (thin epoxy will not match the rough surface well). West system is good, with thickener. Common 5-minute epoxy will
work too for something like this, thickened with perlite
paint additive. Hold in place with 2 small counter sunk screws for 24 hours. The need only be long enough to go through the first layers of glass, just enough to hold it for clamping (brass or ss). Coat the cleat with epoxy while you are at it.
* For bonding, the epoxy should be thickened to a thick jelly consistency, just barely runny.
* Even with a cored hull, it should not be required to add more material to distribute the load. The cleat will be well bonded.
* Drop your shelf on and screw down. Whether you epoxy or
paint the wooden shelf is your call. Much depends on how wet the area is.
Removable and permanent, both.
