In order to make a pair of horn glasses with moist color and comfortable hand feeling, skilled old craftsmen must have rich work experience and superb skills to make a pair of perfect horn glasses. Below we can better understand horn glasses through 16 manufacture crafts of horn glasses.
Above is a pair of vintage style horn sunglasses with round frames.
1.The first is to choose the horn material. Because of the variety of horn and living environment is different, the quality of different horns also varies greatly. Only high-quality horn materials can be used to make horn glasses. Natural horns without artificial treatment have a rough surface, only experienced masters can be qualified to complete the job.

2.Then put it on the cross saw machine, cut off a part of the end of the horn, and then saw the horn from the other end according to the required length into a round tube.

3.According to the specifications confirmed in advance, the two ends of the horn will be sawed off and then broken with a jigsaw to form several pieces of tile horn.
4. Then the tile-shaped horns should be heated at high temperature to soften them and avoid cracking when they are flattened.

5. After heating and softening, hydraulic pressure will be used to flatten the board, and it will become a rectangular horn board after cooling.

6.Use a grinding wheel to smooth out the uneven surface so that a horn board is finished. It is like the production of acetate glasses, cutting large sheet material into chunks according to the specifications of the horn glasses.

11. Use the CNC machine to make the inner and outer rings of the horn glasses. Because the material of horns is very crisp, experienced CNC masters have to rely on molds for positioning, and at the same time ensure that the speed of the machine is above 4800 rpm, so that the shape of the inner and outer rings can be formed at one time.
