Abstract

We have explored by optical microscopy and scanning electron microscopy coupled with energy-dispersive X-ray twenty-two particles and formations of brass located in a sample of the Face area of the Turin Shroud. They differ by the proportions of copper and of zinc in the alloys. The nineteen brass particles are micro-sheets or micro-balls, generally of yellow colour. The p5 formation is representative of the cementation process of brass production, and the k15 formation is representative of the direct process. These brasses were loaded on the Turin Shroud surface at different times during history, to imitate gold powder.
