Marble, Travertine & Limestone

These are all calcium-based stones that are sensitive to acids. These stones are also softer than granite, ranging between 3 and 6 on the Moh scale of hardness.

This does not mean that marble, limestone or travertine are bad choices for countertops, but merely that they will require different care.

Since they will all etch when exposed to acids, we suggest that these materials be honed prior to installation to make maintenance a little easier.

Calcium-based stones are softer and warmer than cold, hard granites and will acquire a graceful patina with regular use.
