Borax Experiment for Rock Tumbling 

Many #rocktumbling enthusiasts have asked if using Borax actually does anything when used during a tumbling run. So we did an experiment.
Short answer: YES.
Experiment: We ran a 7-day cycle without Borax, then another one with adding 1 Tablespoon of Borax per barrel capacity. Example, a 3 pound barrel would get 3 Tablespoons.
Outcome: The weekly barrel clean up was a breeze when using the Borax. It also helped to break the water tension (we have hard water) creating a thicker slurry giving us a better grind during the cycle.
Recommendation: Going forward, I'll add Borax to each barrel, no matter the stage.
