The suggested tumbling times for each grit in the National Geographic Rock Tumbler Kit are as follows:
- Grit #1: 3-5 days (until the stones have all lost their sharp edges and feel smooth)
- Grit #2: 6-8 days
- Grit #3: 6-8 days
- Grit #4: 7-10 days (the long polishing time will help you get the best results)
Please note that these are just guidelines, and the actual tumbling time may vary depending on the hardness of the rocks and your desired level of polish. It is recommended to periodically check the rocks during the tumbling process and adjust the duration if needed. Remember that patience is key, as the best results come to those who wait.
