Travertine Production Process and its Use in Ancient and Modern Rome. Introduction. Travertine is a porous stone that is halfway between limestone and marble because if it is compressed such that when there is enough pressure over time, it can turn into travertine. If the stone is compressed for a thousand more years, it can turn into marble.

Marble is formed from limestone when the limestone is affected by heat and high pressure during a process known as metamorphism. During metamorphism the calcite limestone recrystallizes, forming the interlocking calcite crystals that make up the marble. Metamorphism occurs in limestone when the limestone is located to convergent plate
