Conservation of marble, bronze, plaster, sandstone, limestone, and wooden polychromed and gilded sculptures is one of the major passions and strengths of our laboratory. We preserve artistic authenticity and restore the original beauty of objects from different historical periods and various provenance. This includes Roman times, through small 17 c. Madonnas, to large abstracts compositions by Henry Moore, Antoine Poncet, Karel Appel, or realistic garden sculptures of Sylvia Shaw Judson, and plaster of George Segal.

The Goose by William Turner. Bronze Sculpture. 20th century. Chicago Botanic Garden.

1st Row: sculpture before conservation. Goose was broken off from the base. A layer of grime covered the surface of the sculpture. Original patina had significant discolorations and abrasions.

2nd Row: sculpture after conservation. The goose was welded back to the base to stabilize the structure. The surface was cleaned and a new patina was applied.


The Naughty Faun by Sylvia Shawn Judson. Limestone sculpture. 1921.

1st and 2nd Row: before and during conservation. The sculpture was previously restored unsuccessfully and without sensitivity for the original color and sophisticated details. The cement was removed and the structure reinforced with titanium non-corrosive rods.

3rd Row: sculpture after conservation. The missing fragments were reconstructed reflecting the original stylistic features using original photographs of the work. The reconstruction utilized limestone material to match the original in color and texture.
