摘要:
The invention relates to a glass ceramic or glass body that can be subjected to great thermal loads and is decorated with a color based on a melted silicate containing effect pigments. In order to reduce the protective look provided by the decoration, the melted silicate contains special effect pigments at a predefined ratio, said special effect pigments producing a color-flopping effect on the decorated glass ceramic of glass body. The human brain is hardly able to perceive the traces of wear as the tint changes according to the angle of vision. Preferably, the color-flopping color is based on a melted silicate to which effect pigments are added at a given ratio in the form of synthetic plane-parallel silicon dioxide (SiO2) laminae which are coated with metal oxides.

摘要:
The apparatus performs a forced reshaping of a flat green glass part during a ceramicizing process in which the viscosity of the glass is temporarily lowered due to crystallization heat. The apparatus includes a continuous furnace (3) for the ceramicizing process: a reshaping device (2′) provided with activating openings (6); and vertically movable pressure-operated reshaping tools (9) arranged in the reshaping device (2′). The furnace (3) is provided with lateral openings (4) for temporarily connecting activating lines (8) to the activating openings (6) of the reshaping device (2′) in a sealed manner in order to operate the reshaping tools (9) by supplying pressurized air to the reshaping device or by producing a low pressure in the reshaping device (2′).
摘要:
The method produces a glass-ceramic article substantially in the form of a plate with improved high temperature difference resistance or strength. The glass-ceramic article contains keatite mixed crystals (KMK) or high quartz mixed crystals (HQMK) as well as the keatite mixed crystals (KMK). The method includes heating a glass-ceramic in a high quartz mixed crystal state to form the keatite mixed crystals with a heating rate of 20 K/min to 150 K/min, preferably more than 15 K/min, especially preferably more than 20 K/min. These high heating rates increase the temperature difference resistance.
摘要:
The method produces a reshaped glass-ceramic article by forced reshaping of a flat green glass part during a ceramicizing process with temporarily lowered viscosity due to crystallization heat. To perform the forced reshaping economically the forced reshaping takes place in a continuous oven for ceramicizing and in an oven section in which the viscosity of the green glass part is temporarily lowered as a result of crystallization heat. An apparatus for performing the process is provided in the continuous oven including different active reshaping devices and/or a hollow mold. The method produces glass-ceramic articles with undamaged surfaces corresponding to surfaces produced during the making of the green glass part (smooth or structured, e.g. knobbed).
