Claim:
1. An observation and analysis method for observing and analyzing optical singularities ( 2 ) that deflect light and that are carried at the surface or in the wall of a container ( 3 ) made of glass and possessing an axis of symmetry (S), the method consisting in: illuminating the container by means of a diffuse light source ( placing at least one image acquisition device sensitive to said property of light and to its variation to take at least one view of a container portion that might contain optical singularities when observed from at least one viewpoint (P) along an observation axis (X); and processing at least one view in order to analyze the optical singularities; the method being characterized in that it consists in: illuminating the outside ( with containers of low transmittance, taking the view of the container portion by the image acquisition device receiving light beams coming from a portion of the light-emitting surface ( with containers of high transmittance, taking the view of the container portion by the image acquisition device receiving light beams coming from a portion of the light-emitting surface (
