Controlled diffusion by thin layer coating: The intricate case of the glass-stopper interface

A comprehensive study was carried out to investigate the critical role played by interface between stopper and bottleneck on oxygen penetration into bottle, as well effect of surface treatment stopper. First, compression micro-agglomerated cork, at close 40% (similar that a cork in still wine bottleneck), had very limited transfer. Second, once inserted glass without any treatment, up 99% total transfer took place stopper-bottleneck interface. Third, when coated with paraffin-silicone mixture, there almost no Although initially used slippery agent for easier uncorking, coating stopper, thin layer several hundred nanometers, remarkable unexpected impact control
