Conservation Metallurgy is the application of forensic engineering and metallurgical principals to the conservation, preservation, and rehabilitation of historic buildings, machines, and artifacts. Our services can be used in a variety of contexts whether it be private or public collections where limited or no information is available. Services provided include:

  • Metallurgical analysis to identify the composition and mechanical properties of old components.
  • Coatings (Paint) analysis to identify colour, thickness and composition, including the presence of lead. The colour(s) of all previous coating layers can also be identified.
  • Composition analysis and thickness measurements of metallic coatings.

Testlabs International Ltd. with its complete materials laboratory and engineering experience has offered its services to the following conservation projects of ageing and historic buildings, components and landmarks:

  • The Golden Boy – Manitoba Legislature. Testlabs International Ltd. performed material testing and analysis to identify the composition of the bronze alloy used to cast the Golden Boy, and provided a condition assessment and repair procedures for the statue.
  • Grain Exchange Building – Materials testing and analysis identified the presence of a protective zinc sheeting around the top of the building. Recommendations were provided to preserve this layer when removing layers of paint.

Dr. Wayne Tennesey, P. Eng, has over 30 years of interest in architecture, art and design and wood working/furniture design, which is readily adaptable to conservation testing and analysis.
