Provided herein are novel tools and methods for the formation of vessels having sculpted interior and exterior forms. Novel high-temperature non-woven textile forms may be used to create a glass vessel having a three-dimensional sculpted interior of almost any shape. The non-woven textile forms may also be used as molds to artfully sculpt bottle exteriors. The invention allows for unprecedented control over the form of glass objects in an industrially scalable process.

A production apparatus making continuously curved crystalline glass as a cover or container includes a melting device, a drainage device, a molding device, and a crystallizing device. The melting device melts glass raw material to form a glass melt. The drainage device drains the glass melt to the molding device. The molding device includes a rotating table and a plurality of molding molds thereon. Each molding mold can be moved toward or away from the drainage device by the rotating table. Each molding mold has a molding cavity. At least one part of the molding cavity includes a plane, and at least one part of the molding cavity includes a curved surface to extrude the glass melt with such different surface forms. The crystallizing device crystallizes the curved glass member to achieve the curved crystallized glass member. A method for manufacturing such glass is also provided.

A method for manufacturing an optical element out of glass comprises placing a blank made of glass on an annular contact face of a supporting body having a hollow cross section. The blank is heated on the supporting body in a cavity of a protective cap that is arranged in a furnace cavity, such that a temperature gradient is established in the blank in such a way that the blank is cooler inside than on an outside region. The blank is press molded to form the optical element.

An apparatus (10) and a method of actuating a parison plunger includes transforming linear force applied to a plunger extension (54) into roto-translational motion of the plunger extension (54) via a cam path (98) between the plunger extension (54) and a piston (94).
