Abstract
It has long been noticed, during certain physical and chemical processes with substances containing sulfur, the appearance of violet, indigo-blue, blue and green colors, sometimes remarkable in their beauty. These color reactions are historically closely related to hypothetical modifications of elemental sulfur; black, translucent blue in thin layers, Magnus sulfur and Wehler blue sulfur. The presence of these modifications in ultramarine has been explained by a number of scientists for its varied colors.
