Aged Garden Décor and Efflorescence

Exposing cast stone or concrete items to outdoor weather and elements will always age them. This natural aging process actually enhances the look of outdoor décor items and can give them an ‘old world’ feel. This can make even a very recent purchase appear to be something your family has owned for generations.

The Natural Aging Process

EfflorescenceThe salts found in the natural materials of cast stone, combined with water, touches off a chemical reaction. This reaction is called efflorescence. The degree of efflorescence will vary depending on weather conditions.

Mother Nature often provides rainy, cold, windy weather in the Spring months. Therefore, this touches off and activates that chemical reaction. The calcium carbonate (salt) contained in the raw materials used to make case stone will be drawn to the surface if the item. As a result, you’ll see a chalky white residue on the surface of the piece.

This residue will gradually disappear. Because as more of the same weather conditions occur, this will naturally complete the efflorescence cycle. Once this process has occurred on a cast stone item, it won’t reappear again.

Other Water Processes

Water agingIron oxidization is another natural occurrence that can appear on water containing items such as fountains and birdbaths. Because bowls and basins continuously hold water they are continually wet. The raw materials used as ingredients for cast stone birdbaths contain minimal levels of iron. When iron reacts with water, a powdery pink or orange residue can appear on your birdbath.

Remember, each piece of cast stone garden décor will age differently. Mother Nature will ultimately determine the appearance each piece will acquire as it ages. If you wish you can minimize these processes with some light scrubbing and cleaning with a soft cloth or brush.
