FIELD: technological processes.
SUBSTANCE: method for manufacturing glass products includes the following stages: a) providing moulds with a bottom and a top edge; downloading the molten glass drop to the bottom of the mould; bringing the mould into rotation about the vertical axis causes flowing of the drop along the bottom of the mould due to the centrifugation and getting thus a glass blank corresponding to the product form; and extracting the product from the mould immediately after its cooling. Prior to stage b) a restrictive ring is placed on the upper edge of the mould. In stage c) this restrictive ring is brought into rotation by means of the mould. This allows to stop the raising of glass by means of the restrictive ring, and also to obtain a glass product of complex shape. The restrictive ring (30) is brought into free rotation on the support (34), provided with the possibility of vertical movement in the direction of the vertical axis (XX) from the near position, where the restrictive ring is in contact with the top edge (16) of the mould, and the distant position, where the restrictive ring is at a distance from the top edge (16) of the mould.
EFFECT: improving the method of centrifugation for a greater variety of feasible forms and the ability to manufacture products of complex shapes.
