There are a number of causes for yellowing marble—and a number of possible cures. The most common culprit for white marble turning yellow is iron, which can be found in many natural stones. When exposed to water, acids or bleach, the iron in the stone will begin to oxidize and turn it yellow. Other causes may include wear and tear, improper cleaning, wax buildup, and crystalization.
Loose tiles are most often a result of debonding and delamination. Debonding happens when two materials are supposed to stick together, but don't. Delamination happens when layers of laminated material separate. There are numerous reasons why these problems occur.
