Modern day pollutants destroy a significant amount of detail that was meticulously sculpted by the artist. The remaining finer details are obscured by corrosion and are harder to enjoy visually. The typical green and black colors, known as the patina, associated with older bronze sculpture is destructive when produced by nature. The surface should be cleaned and sealed, by a professional to protect it from nature's corrosive atmosphere.
The Royalston Arts Foundry is thoroughly engaged in working to preserve outdoor bronze sculpture in towns throughout New England and beyond. If there's a memorial that you feel needs attention the time is now. Contact us and we will provide an analysis.
The Royalston Arts Foundry has been providing quality casting, refinishing, and repair to bronze and other non-ferrous alloys since 1982. Our finishes are designed to withstand many years of weathering when maintained properly.

Royalston Arts Foundry offers high quality precision non-ferrous sand castings for the hydroelectric industry. We can cast in bronze or any other special alloy composition. Sand blasted and painted surfaces are available upon request.
Although bronze can be more expensive, its surface finish has corrosion resistance and anti-fouling abi1ities, allows for a longer life span and provides increased hydraulic efficiency, A comparison of bronze with cast iron and other alloys shows that the deterioration factor of bronze is far superior, it is more resistant to cavitation damage and aquatic fauna will not grow on bronze because of the high copper content.Return to Top of Page
"Nessie" in two pieces
In 1988 the Royalston Arts foundry started their own crafts line. After countless years of Christmas shopping we realized the entire market was saturated with foreign imports. The look of all the bronzes are the same, every-one carries highly polished brass and bronze casting. Our surfaces are each unique and have a personality of their own.
The basic process
We begin by designing each item in clay. The clay is then baked and will be used for reproducing the design in bronze using a sand mould. To make a sand mould, a reusable water based sand is tamped around this clay pattern into two halves of a metal flask. The two halves are separated, the pattern is removed leaving a cavity in the sand. The two halves are put back together and the molten bronze is poured. Once the bronze has cooled the sand is shaken out. thus exposing the casting. The casting will require grinding and is then sandblasted in preparation for its finish known as a patina.
A true patina is a subtle and desirable quality brought about in the course of time by OXIDATION. The color depends upon environmental conditions..For example sulfur in the city atmosphere will turn bronze black. If sited by the sea, bronze will turn green due to the salt air. To hasten the oxidation process of our finished bronze casting we brush on different solutions and apply heat using a blow torch to achieve the desirable finish. Many factors govern the results; temperature, strength of our solution and composition of the bronze, just to name a few. For this reason no two patinas are identical.
