Mexican Noce is quarried near Torreon, Mexico. This sedimentary stone is formed in hot springs which is composed of calcite calcium carbonate. Like all travertines, the cavities were created when the carbon dioxide bubbles were trapped as the stone was being formed. The travertine is filled with a colored cement three days before the honing process, allowing time for the cement to dry. During the dry summer months, the cement will cure faster, and in the more humid parts of the year, the cement will dry much slower. This variation in curing can alter the overall tone of the fill.
