In 2004 I found in an old book a receipt for Phosphorescent Paint and Enamel and I have been experimenting for over a year to find a way to produce a bright, luminous powder from sulfurized oyster shells. The powder does not have the purity of modern illuminants such as Super-LumiNova, which is used in the watch industry for example. The powder or granulate is also too coarse to be used for printing. It is also not completely homogeneous in larger areas and the result sometimes appears somewhat blotchy. But it is 100% natural and impresses with its strong and long-lasting luminosity, which will last for years if not forever. For illuminating my watches, I combine the luminous powder mixed with clear, transparent cold enamel.
