Materials analysis utilizes a host of scientific equipment and methods to identify unknown materials (such as coatings), and characterize historical and architectural materials (such as brick, metals, mortar, or paint) as well as identify their composition and compatibility with other products. Some techniques, such as paint analysis, can also be used to determine the approximate age of various building elements. Recommendations are provided to guide field work; in some cases a preservation professional can come out to collect samples for analysis.
Laboratory testing can be used to evaluate the compatibility and performance of products and treatments for use with historic materials. Methods such as accelerated weathering allow technicians to evaluate the performance of a material or product over time. Recommendations based of this testing are provided to guide field work.
