Résumé

When examining the alloy of several works of Adam van Vianen, who was one of the founders of the Dutch Kwabstijl, with X-ray fluorescence, a much higher silver and lower bismuth percentage and was found in the silver than was commonly used by his contemporaries. It is the hypothesis that Van Vianen used a high percentage of silver, as it is more malleable, and he could therefore obtain extreme deformation of the silver without the formation of cracks. Recipes on silver production and refinement in the silversmith workshop that would have been commonly used at the time were selected to serve as a basis for making reconstructions in silver. These books were-the Probierbuchlein by Calbus of Freiberg and the Description of Leading Ore Processing and Mining Methods by Lazarus Ercker. Reconstructions were made, and the 'test' procedure, leading to 'blick' silver, generated highly refined silver, the silver being very malleable. It is therefore concluded that this recipe could have been used on purpose by Adam van Vianen to make his elaborate objects. On the other hand, there exists the possibility that this low bismuth content might be generated by coincidence, as a side effect to the multiple annealing and pickling cycles the objects went through.
