Exterior Terra Cotta Conservation

• Preliminary conditions survey of terra cotta elements

• Laboratory testing of repairs and coatings

• Development of associated conservation repair methods and materials, including coating and patching materials

• Development of replication mortar for terra cotta and brick

• Identification of material sources

 ICR began with a visual survey of terra cotta elements on the Water Tower and extraction of cores for laboratory analysis. Microscopy of these cores revealed detachment of glaze from the tile substrate which led to a close-up investigation of terra cotta elements. The unusual glaze surface conditions identified were due to the proximity of the sea. ICR conducted water vapor transmission rate tests to inform testing and selection of appropriate patching and repair materials. Additional testing focused on development of compatible mortars and patching materials. Pigmented and clear masonry coatings were also tested to identify a coating for the terra cotta with compatible physical and aesthetic characteristics.
