Jasper polishing method:
1. Grind the position to be polished with the sand stick with the finest sand grains in hand, and drip water while grinding, otherwise scratches will be polished;
2. After polishing feels smooth, clean the polished part with toothbrush and water. Uncleanness will affect the next polishing;
3. Dip the cowhide strips with some diamond powder mud by hand. Do not use water, repeatedly wipe the polished parts. If the cowhide is too soft to be fixed, you can stick it on chopsticks or grinding sticks.
4. After feeling very smooth, wash the polished part with toothbrush and water, and it will be ok.
The post office is not allowed to send diamond powder. If there is no diamond powder, just rub it with cowhide a few times and it will be shiny.
