Everyone knows that uncoated iron will rust if exposed to moisture. Fortunately cast iron's crystalline structure is laced with carbon particles that concentrate on the surface as the iron molecules oxidize. This stops the oxidation effectively sealing the material from further deterioration. The only problem with rust is that it will rub-off or stain anything that comes into contact with it. A sealer or finish is therefore desirable especially for furniture pieces or items mounted atop porous materials that may stain.

Historically speaking cast iron was always painted to resemble more expensive materials such as marble or bronze. Details were often picked out in gold leaf or contrasting colors. It was only in the twentieth century that ironwork was slathered with many coats of white paint. Today Robinson Iron has been asked to develop all sorts of specialty finishes _ even a "rusted" look. This is achieved with chemical patina and clear satin polyurethane sealants and sometimes through the use of acrylic polyurethane paint applied with spray bottles.

A quick and easy method used to marbleize an urn requires a large container of water. Drizzle several alkyd oil based paint colors onto the surface of the water. Take the urn, painted in a desired background color, and lower it gently into the water. As the urn is dipped swirls of floating paint adhere to the surface marbleizing the piece. After allowing the paint to dry thoroughly apply a coat of paste wax and buff to a soft luster. Dispose of all remaining materials properly and in an environmentally conscientious manner.
Other popular effects are antiqued bronze, aged terra cotta, carved limestone and gilding. Gilding requires the use of genuine 24 carat gold leaf especially if it is an exterior application. "Dutch" gilding with imitation gold leaf is suitable only for pieces that will not come into contact with moisture. They must always be sealed with varnish to prevent tarnishing.

When requesting specialty finishes try to supply a photograph, swatch, sample card or item to match. This provides the colorist with a frame of reference. Remember, the appearance of most natural materials is made of many colors in varying shades and tints. When asked to "paint it the color of the Statue of Liberty" one must remember that such a request encompasses an extremely broad range of green/blue-blue/black colors depending on ambient light and the time of day the statue is viewed or photographed.

Decorating trends and tastes are constantly changing. What effects will be popular ten years from now we can only surmise. Perhaps you will be the one to request tomorrow's "hot" new look. Whatever the case Robinson Iron colorists stand ready to assist you with a variety of time tested techniques.
