The Georgia State Capitol in Atlanta, GA.
The investigation, analysis and restoration of historic finishes at the Georgia State Capitol is one of Welsh's largest, most complex and most successful endeavors. The building is a National Historic Landmark in the neo-Classical style, designed by the Chicago firm of Edbrooke and Burnham and built between 1884 and 1889. The main entrance on the west façade has a pedimented Corinthian portico. A gilded Renaissance Revival dome crowns the eight-story central Rotunda. Large, arched clerestory windows light three-story atria in the building's north and south wings.
Welsh conducted an extensive examination of all the painted and naturally-finished architectural features in several major areas of the Capitol as part of a comprehensive restoration of the building conducted by the architectural firm Lord, Aeck & Sargent of Atlanta, Georgia. Our participation in the multi-phase project continued over five years, and the scope of the examination included the following spaces: Exterior; First Floor offices and corridors; Atria, Rotunda and entrance lobbies; House of Representatives Chamber; Senate Chamber and the Appropriations Room. The lab analysis included the use of stereo- and polarized light microscopes, micro-FTIR and a spectrophotometer for color evaluation.
The House of Representatives, Senate Chamber and the Appropriations Room (originally the Supreme Court) received ornate decorative treatments with intricate polychrome schemes designed and executed by the Almini Company of Chicago. An article published in the Atlanta Constitution on February 10, 1889 refers to the elaborate decoration of the House chamber:
The rich colours of the fresco [oil paint on plaster] give the room an appearance of magnificence. The walls are painted a dull red in keeping with the cherry [wood] finish and the pilasters are a darker shade. The frieze and capitals are in colors varying from a rich dark red to gilt old gold and buff with a delicate tracery of antique blue. Above the cornice is another tracery of delicate blue figures and above that the cove of the roof is a mass of gilt stars and spangles. The flat ceiling is broken into panels by heavy girders. The panels are antique blue ornamented with silver figures and the girders are painted in rich, darker colors.
Though not as extensive as those found in the larger House chamber, the decorative finishes in the Senate were quite impressive. As described in the same newspaper article,
the painting in the senate is in keeping with the white oak finish and the colors of the fresco, rich and beautiful beyond description, and less gorgeous than those of the house...
Such historic documentation and a detailed historic photograph of the House Chamber aided in determining the locations of the stencils. The decorative work and color palettes in the legislative chambers were extensive, incorporating 48 colors and 19 distinct stencil patterns in the House and 25 colors in 20 stencils in the Senate. Using solvents, we removed subsequent paint layers and exposed a complete repeat of each original pattern. We took paint samples from these exposure windows for color evaluation and made tracings of the stencil patterns, from which drawings and new stencils were created.
