Note: Owner Information Source

PreColumbian Master; Panama Gold

Note: Object Description

Open back cast pendant with all details made in the wax model. The surface appears enriched as it is gold colored while the interior is coppery. There is some visible porosity and pits from casting. A suspension loop is present in the open back and there is a lump that may be a casting flaw

Note: Owner Accession

3 metal objects (one of gold and two of copper gilt) from Chiriqui, province of Panama, South of boundary of Costa Rica. Purchased from C.H. Soar Order # 57337. $55.00. The above were forwarded from San Francisco by the Dr. Walter Hough, and are excellent examples of the metal work of the ancient peoples

Note: Research Notes

Museum purchased from Henry Soar in 1915. No reference to who excavated them. Cannot yet find info on Soar

Exhibit Hall 23 9-17-74

Note: Condition Review

The object is whole but there is evidence of cracking and corrosion in several locations. A large crack is visible through the "wings" near the head of the pendant. The surfaces are heavily scratched, revealing in some areas the copper colored alloy below. Likely cleaned in the past as only a very small amount of green corrosion present. Black corrosion also visible in some areas. Adhesive-like material visible at attachment of elbows to body and in crack of headress at back

Note: Follow-up Notes

XRF: Analyze the sides of the wings, body, and suspension ring. Possible candidate for X-radiography as the flat headress/wings has interesting join/crack

Note: Analysis Recommendations

XRF X-ray radiograph

Condition: Corrosion

Note: Green-surface; black-core. small amount of green corrosion present. Black corrosion also visible in some areas

Condition: Coloration

Note: Gold; Coppery; Green corrosion. Gold colored surface with coppery color at interior.. perhaps from casting

Condition: Usewear Toolmarks

Note: Heavily scratched, perhaps from past polishing or cleaning. The raised surfaces on the back of the suspension loop and back edges appear more polished and rounded, perhaps from wear.

Condition: Pseudomorphs

Note: None

Materials:

Gold Alloy Note: Gold colored surface with coppery interior. Deep scratches reveal copper color below surface. A few very small areas of green corrosion

Technique: Fabrication Method

Cast- Open Back Note: Open back cast. All details done in mold. porosity and pitting from casting is visible on surface. Casting flaw in back and at bottom, perhaps due to pour from top. The thin band at the top may be hammered but there are not obvious marks

Technique: Joinery

Note: All cast. No evidence of joinery outside of wax model

Technique: Finishing

Note: All in wax model Polished Surface Enrichment. Gold surface appears compact and shiny, likely burnished.
