Definitions
- the invention relates to a method for marking a glass material.
- the invention also relates to a marked glass material.
- a method for marking a glass material in which the glass material is in the molten state chemical element or a group of chemical elements (hereinafter also called chemical element for short) is added, the chemical element in the solidified state of the glass emitting a light or a light spectrum outside the waveband of visible light.
- chemical element a group of chemical elements
- the individualization of the manufactured glass object cannot therefore be easily seen.
- the glass material can be completely colored depending on the type of application. However, it is also conceivable that only very specific, for example punctiform areas are marked and are difficult for a forger to find.
- a substance that fluoresces in the infrared light range can be used as the chemical element.
- Such substances are, for example, antimony, lead oxide or zinc oxide.
- a chemical element is assigned to the melt, which fluoresces in the ultraviolet light range when the glass material solidifies.
- the elements from the group of oxides of the side earths can be used.
- a large number of light spectral ranges can be created, by means of which the glass material can be individualized.
- the percentage by weight of the chemical element in the glass material can also be varied, so that the number of different possible spectral ranges can be potentiated. This enables the user to change the color of the glass object at regular or irregular intervals. This further increases the security against counterfeiting.
- a glass body containing the chemical element is produced, that this glass body is inserted or attached in the liquid, doughy or solid state in or on a carrier glass not marked with the chemical element.
- the glass body can accordingly be worked into a recess or an opening in the carrier glass.
- a glass body to be produced and pressed into a carrier glass. This must be done in the pasty state of the carrier glass.
- the glass body is designed as a tag.
- the invention also relates to a glass material which is produced by one of the above methods.
- the object of the invention is also achieved by a glass material which has a glass base substance, into which a chemical element or a group of chemical elements is introduced, and the chemical element in the glass material emits a light or a light spectrum outside the waveband of visible light.
