Title: Preliminary Simulation of the Corrosion Rate of Archaeological Glass

In this study, we make use of a micro-continuum modeling approach (the Kinetic-Microscopic-Continuum Model or K{micro}C model) to capture the spatial distribution and identity of reaction products developing over time as a result of the archaeological glass corrosion, while also matching the time scales of alteration where possible. Since the glass blocks sat on the Mediterranean seafloor for 1800 years, the physical and chemical boundary conditions are largely constant. We focus on a fracture within the glass block identified by Verney-Carron et al. (2008) and simulate it as a 1D system, with a fixed concentration (Dirichlet) boundary corresponding to the interior of the fracture.
