Last Thursday i have been at Museum Veste Coburg in northern Bavaria and had a long and very interesting conversation with the museums director Dr Alfred Geibig who gives me some valuable hints. The red colour of the fabric in Marcus den tooms qouites can be a result of a chemical reaction of mercury and sulfur forming cinnabar compounds. Cinnabar is a bright red pigment which was often used in arts. Many early authors of fireworks books and works on blackpowder were recommending the addition of metals such as mercury to powder mixtures. According to modern chemical knowledge the mercury as no positive effect on the powders brisance and its use was maybe based on a spiritual background according to early alchemy.
