GET TO KNOW YOUR STONE

The first step in proper stone care and maintenance is to understand your stone's geological classification and composition. This information will help you to identify what cleaning products to use and how best to care for your natural stone. It will also ensure your complete satisfaction and provide years of long lasting durable beauty.

Natural stone is categorized into three basic geological classifications by their respective formation processes: Sedimentary, Metamorphic and Igneous. Additionally, stones in each category can be either Calcareous or Siliceous.

Calcareous stone is composed mainly of calcium carbonate, a chemical compound commonly found in natural stone, shells and pearls. Calcium Carbonate is sensitive to acidic solutions so mild, non-acidic cleaners are recommended.

Siliceous stone, as the term implies, is one composed primarily of silicates, such as quartz, feldspar, mica, etc. as such, a siliceous stone is generally resistant to most acids found in kitchen settings, although acidic cleaners are still not recommended, as these stones may contain trace levels of minerals that are acid sensitive.

TYPES OF FINISHES

There are a number of finishes that can be produced on some natural stone surfaces. Below are a few of the more commonly seen finishes:

Surface Finishes
POLISHED

Grinding, sanding, and buffing produces a high gloss, mirror-like surface

HONED

Grinding and sanding produces a smooth, yet not glossy finish. This is best for low maintenance, high traffic applications.

FLAMED

A flamed surface is achieved by subjecting the stone to the high temperature flame of a torch and burning most of the carbon content, leaving textured quartzites with gentle coloration.

LEATHER

This finish gives the stone a suede look and feel. This texture is smooth and slip-resistant.

CROSS-CUT

The cross-cut method involves end-cutting blocks of travertine to display a less linear, more rounded "wavy" pattern.

VEIN-CUT

Opposite of cross-cutting, the veining of the stone is shown as a linear pattern.
