Method of calibrating a glass enclosure closed at one of its ends, in which the casing is applied under the effect of heat and vacuum against a gauge constituted by parts displaceable from each other, characterized in that the parts of the gauge can move radially between yes and be brought to the working position by separating them so that the outer diameter of the gauge is equal to the desired inner diameter of the casing, after which the glass of the casing initially too large is heated in such a way that, under the effect of the emptiness practiced in the envelope, is applied against the parts of the caliber without penetrating, however, in the grooves that are between the various parts of it.
