Abstract

The present invention discloses a method for the preparation of a polycrystalline glass-ceramic comprising mixing raw materials capable of crystallization, heating the mixture of raw materials to form a molten glass and subjecting the molten glass to a heating and cooling temperature regime to bring about crystallization and form a polycrystalline glass-ceramic, characterized in that, prior to crystallization, pigment is added to the molten glass in a coloring unit comprising a changeable chamber for receiving the molten glass and pigment and/or the molten glass is subjected to a rolling and forming process comprising the use of horizontally (5,6) as well as orthogonally (16,17) positioned rollers, relative to the glass ribbon (18) . The present invention further discloses a coloring unit for coloring a molten glass in a device for manufacturing a poly-crystalline glass-ceramic comprising a separate changeable chamber for receiving the molten glass and pigment. The present invention finally discloses a rolling and forming unit for rolling and shaping the molten glass comprising at least one pair of horizontal (5,6) as well as orthogonal (16,17) rollers.
