Résumé:

he objective of this work is to compare density and density fluctuations of silica as a function of temperature in the anomalous domain between 950 and 1480°C via Archimedes' macroscopic measurements and light scattering. Parallel qualitative behaviour is also recorded between density fluctuations and macroscopic density. Density fluctuations of silica show a minimum as a function of temperature, as with macroscopic density. This correlation indicates a possible common origin of both observations.
