Microscopic analysis of sectionsl samples offers obvious advantages over conventional surface examination when studying the composition, condition, interaction, properties, and behavior of individual layers. When considered concurrently with art historical and aesthetic aspects of artistic and historic objects and surfaces, information on individual layers and their interaction with other layers in constituting a surface can have a direct and practical bearing on surface-related treatments, such as consolidation, cleaning, and varnishing. Access to this information typically requires a sample, and the time, materials, and equipment for analysis. An ongoing research project at the Williamstown Regional Art Conservation Laboratory focuses on practical aspects of microscopic sectional sample analysis of thick and thin sections using visible light ans fluorescence microscopy. Aspects of the project were presented, including a general overview and several novel techniques for preparation and examination. This postprint article reports on several practical developments for sample preparation and an interesting use of the dtage microscope for surface analysis of objects; other aspects of the project (microtomy, fluorescence microscopy, solubility testing, and media characterization) are not covered herein, but will be incorporated into notes for future workshops. -- CAL
