Do I need to use oil or will water suffice? I ran across this video and would like some feedback. Specifically
- Can I use water? Will there be any long term negative impact on the stones? (I am guessing no as they have survived millions of years in the earth)
- I am guessing its ok to go to oil from water, but what about the other way around?
- Clogging: Water vs Oil. Guessing Oil has more specific density to keep the metal out of pores. Am I correct?
