Manufacturing a natural horn spectacle frame

 

 

The preparation of the horn and the colour choice are crucial criteria for the quality of a buffalo horn frame. Water buffalos have hard and solid horns.

 

  • The blanks for spectacle manufacture are cut out longitudinally from the solid part. The so called "vase horns" are in the upper part hollow and only the point is solid. These are first split in the direction of the fibres, then heated and pressed.

  • From these pressed half horns, blanks are cut out, which are then used for the spectacle manufac- ture.

  • New techniques now make it possible to combine different kinds horn with each other, which makes new colour variants possible.
    Additionally other natural materials such as silk and root wood can be inlaid. Due to the various combinations it is now possible to manufacture horn spectacle frames in a multitude of colours and designs.

  • The manufactured blank, whether it is made directly from a single solid piece in a natural colour or out of a number of layers set together, is the starting point for a spectacle frame.

  • Here, first the inside and then the outside shape of the spectacles is milled out, whereby at this stage of the process the form, colour and grain of the spectacles are determined.
    Then they are ground to the required shape using a grinding wheel. The next stage of the spectacle manufacture is to file and scrape the spectacle by hand.
    After the form of the spectacles is basically finished, the hinges are fitted into the drilled holes, using heat effect. Quality hinges of German manufacture are used.
    Ladies who have a special intuitive feeling perform the final polishing of the spectacle frame. This polish also gives a protection against natural environment influences.

  • Finally, all frames are subjected once again to strict quality control. Only products in perfect condition are allowed to leave our premises.
