Partial Immersion Technique for the Photography of Sand Grain Surfaces

George R. Fournier

ABSTRACT

A new technique is described for the photography of sand grain surfaces utilizing an ordinary monocular microscope. By partial immersion of the sand grains in glycerine, and employing the pinhole diaphragm on regular objectives, photographs ranging between 50 and 1000 times magnification can be obtained with enough resolution to satisfy the requirements of routine work. The simplicity of the method plus its low cost may add a practical tool to further the research on sand grain surfaces.
