Timescales and grit preferences for tumbling glass to a mirror finish

[mick]

I am no authority on glass, but I have friends who tumble their stone for at least a week for each grit

Thats why i was asking on here, the timescales online vary wildly but we are running a batch for a very long spell now to see how it turns out

I am hoping it was the low quality of the zinc oxide that caused our issues and the next batch we run turns out exactly how we want. We are not trying to take all the natural marks away but more trying to let the surface shine.
