Abstract
Diamonds are marked by applying apertured tapes bearing identifying indicia to the girdles, applying a flammable layer over the apertured tapes, and then igniting the flammable layer to burn the indicia into the girdles. Preferably, the flammable layer is prepackaged within the apertured tapes.
Claims17
A heat marking system for marking an object having a melting point, comprising:
- a) a carrier tape constituted of a material resistant to a temperature above the melting point of the object, the carrier tape having an adhesive layer and cutouts extending therethrough;
- and
- b) a flammable medium supported by the tape and filling the cutouts in a pattern corresponding to indicia to be marked on the object, the flammable medium being burnable at a temperature greater than the melting point of the object to burn the object and transfer the indicia pattern to the object upon burning of the flammable medium.
A heat marking system for marking a diamond having a melting point, comprising:
- a) a carrier tape constituted of a material resistant to a temperature above the melting point of the diamond, the carrier tape having an adhesive layer and cutouts extending therethrough and arranged in a pattern corresponding to indicia to be marked on the diamond;
- and
- b) a flammable medium supported by the tape and filling the cutouts, the flammable medium being burnable at a temperature greater than the melting point of the diamond to burn the diamond and transfer the indicia pattern to the diamond upon burning of the flammable medium.
A method of marking an object having a melting point, comprising the steps of:
- a) forming cutouts in a pattern corresponding to indicia to be marked on the object through a carrier tape;
- b) filling the cutouts with a flammable medium which is burnable at a temperature greater than the melting point of the object;
- c) mounting the tape with the cutouts filled with the flammable medium on the object to be marked;
- and
- d) igniting the flammable medium to burn the object and transfer the indicia pattern to the object.
2 more elements
A heat marking system for inscribing a gemstone having a melting point, comprising:
- a) a fire-resistant carrier tape constituted of a metallic material resistant to a temperature above the melting point of the gemstone, the tape being mounted on the gemstone;
- and
- b) a flammable medium supported by the tape and arranged in a pattern corresponding to indicia to be inscribed on the gemstone, the flammable medium being burnable at a temperature greater than the melting point of the gemstone to burn the gemstone and inscribe the indicia pattern to the gemstone upon burning of the flammable medium.
