Rock tumbler times


#1

Hello, Does anyone have any suggestions as to how much time it
takes for tumbling rocks,or glass pieces? We have tried for as
little as 15 minutes and as long as 1/2 hour. We would like to
have the glass come out like “beach glass” with the rounded
edges. Please respond to me privately at: @kdesigns Thank
you for any help that anyone can provide! Kim in VT

Hi Jennifer,

I don’t know specifically about beach glass, but my guess is
that it would take closer to a week (24/7) to tumble beach
glass. I tumble rocks, and it’s a three-part step of which the
first is tumbling them with steel shot and water 24 hours a day
for a week. Then there’s a week more of tumbling with less
abrasive medium, and then another four days with polishing
compound, for a total of 18 days.

Recently, someone in Ganoksin noted a book on tumbling, within
the past couple of weeks. If you check the archives you can get
the name of it and receive more specific on what
media you should use and for what length of time.

Happy tumbling!
