Step 1: find a cloth bag, put the olive core in the cloth bag, put the mouth of the cloth bag firmly, and play with the olive core for a week through the cloth bag plate. Is to polish the edges and corners of the olive core and the burrs of the olive core.

Second, a week later, we took the olive core out of the bag, dipped it in a little olive oil with a fine brush, and brushed all the surfaces of the olive core with a brush to prevent the olive core from being blown apart by the wind.

Step 3: Use a soft cloth (special gloves are best) to play with the olive core for a week, then a layer of patina will form on the olive core, so as to avoid the color difference caused by dirty things entering the gap when playing with the olive core by hand.

Step 4: after playing with the soft cloth tray, a layer of patina is formed on the surface of the olive core. At this time, you can play with the hand board directly, and try not to play with the sweaty hand board. The surface of the sweaty olive pit is black and red, which is not good-looking.

Step 5: When playing with the olive core, you must brush the olive core irregularly with a soft brush to brush off the dirty things on the olive core to avoid pigment precipitation and affect the follow-up effect.

Step 6: Play with the olive core for a long time, and beautiful patina will be formed on the olive core.
