Description
The Grotto of the Shrine of Redemption is a religious site in West Bend, Iowa. The large structure is made of a variety of minerals and rocks, some synthetic, that can be studied. Many of these synthetic rocks are a product of smelting crayons together. It was found that several of these synthetic rocks were fluorescent. Those found in the Grotto of the Shrine of Redemption were studied with fluorescence spectroscopy and cross-referenced with knowledge of pastel dyes in use in the 1930s. It was found that some of the fluorescing rocks were likely made using crayons containing various red madder molecules based on their emission wavelengths.
