This research project is about bringing a fundamental understanding of the glass frosting process and its different corresponding chemical processes.
Indeed, although this process is higly used in the glass industry, there is only few fundamental researches that were led on the whole glass frosting process.
This project will try to answer to these questions : What are the different chemical steps that lead to glass surface microstructuration, giving this matt aspect of a frosted glass ? What are the roles and influences of each chemical used in the etching solution on the reaction kinetics and on the glass aspect?
To try to answer to these questions the glass dissolution mecanism and its kinetics are studied via gravimetric analysis of glass substrates and ICP analysis of etching solutions. The precipitate occuring on the glass surface during the frosting, leading to the microstructuration will be characterized and its kinetics will be determined.
