The Cyanotype process was developed in 1842 just after the invention of Photography. It was discovered by the English chemist Sir John Herschel. The Cyanotype works by mixing together two raw chemicals (Potassium Ferricyanide & Ferric Ammonium) and then exposing the image to a source of UV light.
The image has been set into a glass pendant and each necklace will come with a black piece of waxed cotton cord. Please note that the number in the title is a reference for me, not the number of items you purchase.
