Abstrakt: Experiments done with Congo red crystals and with Congo red deposits polished in a single direction by a glass wheel have shown that the appearance of green polarization color primarily depends on near-perfect parallel alignment of the dye particles. The green polarization color was seen only in the deposits which showed a clear transition from red to colorless when examined for dichroism. Another factor was found to be the thickness of the object, as the green polarization color was not present in too thick or too thin sections of amyloid-containing tissues stained with Congo red.
