Abstract
The invention relates to a method of fabricating a glass container, the method comprising a forming step of forming molten glass in order to obtain a semi-finished container (4) comprising a shell (5) presenting inside and outside faces (7, 8), a cooling step during which the semi-finished container is in a transient state in which the glass forming the outside face is sufficiently viscous for it not to deform under the effect of gravity, while the glass forming the inside face is sufficiently fluid to allow the inside face to deform under the effect of gravity, the method including a shaping operation while the semi-finished container is in the transient state, in which operation the semi-finished container is maintained for a predetermined time in a position that is inclined relative to its upright vertical position in order to modify the shape of the inside face under the effect of gravity.
