I can't seem to find a spell to strengthen, or reinforce stone, or convert from SDC to MDC (a la Ironwood for wood. I don't know if it just doesn't exist, or if I'm looking in the wrong places. Can anyone help?

Mend Stone (Earth Warlock) might work at reinforcing stone, I don't think there is a spell to turn SDC stone to MDC (though Sculpt and Animate from Earth Warlock suggests it might be possible with a spell combination since it yields up a Stone golem).

World book 9 has psionics that can harden stone.
