Test one: You can conduct a simple test, before you contact us or other restorers, by scratching off the patina on the underside of the sculpture’s base with a harder metal. If the scratch reveals a copper / gold / yellow color it is bronze. If it is silvery gray color, it is Spelter. If it scratch easily and feels like plastic, it is resin.
Test Two: Lift the item in your hand. Bronzes are extremely heavy. Spelter and resin are both comparatively light, but they are sometimes attached to heavy wood or stone bases to give them extra weight. Turn the item upside down and determine if it feels top heavy. If it does, it is most likely Spelter or Resin and not an authentic Bronze.
What Repair Type Should I Choose? Welding or Adhesive?
With high value sculpture, one might consider museum-quality repairs (reversible repair) as compared to welding. It is an important decision because restoration of metal sculptures using welding or brazing, that generate intensive heat, damages relatively large areas of the original patina requiring repainting / antiquing covering a much greater surface than the break area. Welding is not a “reversible” repair which museums prefer not to see. The preferred method of high value sculpture repair is using metal pins and adhesives.
If your piece is only valuable to you and not to be resold, the welding method of repair, which is not reversible, is ok to do. Welding is a stronger and sturdier repair if compared with adhesives, although new and modern adhesives are pretty amazing when used properly. If one of our customers owned a sculpture worth $20,000, we would not want to see or recommend a restoration using the welding process.

Care and Maintenance
Keep metal sculptures away from moisture. Avoid placing it in an area where it is susceptible to rain or in a damp basement or garage - they will corrode. Aging patina is desirable; do not rub off the patina or aged brass to regain the shine, it will reduce the item’s value substantially. Do not use metal cleaners or abrasives that will take the patina off. To clean, dust the sculpture with a terry cloth towel.
