Repairing damaged marble veneer in kitchen
You could carefully drill a small hole from below, into the bubble. Then make a small slit in the bubble with a fresh razor. Get some five minute epoxy into the bubble via the slit, then use a vacuum to apply suction to the hole you drilled while gently pressing down on the bubble.
