In order to validate the historical glassmaking recipes found in archival sources, we present an innovative experimental method of glass synthesis using the correct raw materials and the most appropriate heating processes. Different fusing procedures and variations of initial ingredients influence the final composition of glass. Therefore, our aim is to study these relationships to gather further information about glass provenance and age, but also about raw materials trade and transmission of handcraft knowledge between different cultures and centuries.
LA-ICP-MS and SEM-EDX are the techniques we use to investigate the composition of starting ingredients and final glasses. A first publication on Medieval Northern European glass-type synthesis is now in progress. This year a new project kicked off focussing on differences and similarities between Antwerp “façon de Venise” glass and actual Venetian glass of 16-17th century.
