Hi Mr T
Aaargh! I think many of us know the feeling, when trying to repair something causes more damage than anticipated.
Is the slate split into 2 separate layers through natural bedding plane, or is it split through its thickness into 2 separate pieces?
I used this stuff to repair a broken sandstone hearth:

I had to repair the masonry below to make a firm bed for the repaired stone to sit on, so that it was fully supported.
The front hearth, which I think you're talking about is resting on the joists in my house - is it the same with yours?
Please let us know some more details of the break, and your hearth construction.
I'd not want to rely on just the strength of the repair, I would want to make sure that the hearth is properly supported at the broken section so that there's no danger of it breaking / going through the ceiling or into the floor void with someone standing on it!!!!!

thanks Ian,
The heath is spilt into 2 neat pieces of 2/3 and 1/3. The spilt is vertical and reasonable straight.
My hearth is laying on stone/brick/cob/rubble built upto floor level. It is reasonabley level and supports the hearth at all points. I would be able lay a thin layer of mortar under the hearth so I guess join would be secure vertically.

Just wondered if it had split horizontally (riven) as you tried to lift it out.
It sounds like you should be able to make a good repair, as both parts of the hearth can be fully supported, as you have stated.
Try to keep the glue off the surface, and wipe any excess off before it sets rock hard.
The joint will be visible, but from your description it sounds as though you should be able to get a neat joint.
The adhesive dries to a mid grey colour, so keep it as thin as possible or it will look awful.
I reckon you'll get an excellent repair though - good luck.
