In case any one wondered, it can take over a month to make a small rock nice and smooth using a rock tumbler. I did not know this. My son received one for x-mas, and I thought “Awesome!” because I’ve always wanted one, and he loves rocks and crystals and stuff, so this would be a cool thing we can enjoy together. What I didn’t factor in was that most rocks are created over thousands of years of sediment and pressure, or a LOT of heat and… pressure. Therefore, rocks are hard and dense. Even the not so hard looking ones.
The first set of instructions (3 parts total) pretty much read like this:
- Put rocks in tumbler
- add grit
- add water
- wait a week
Right. A week. Part 2 is the same, except its a medium grit for 14 days! and then another 7 with the fine grit. So, we let the tumbler go in the garage for 7 days (it’s way too noisy for anywhere else in the house). and now the small pile of rocks looks like:
I wish I’d taken before pictures, but really, they were just lumps of rock. The above shows a VAST improvement.
And we have actually been having fun with this, despite the waiting. So, later on tonight or maybe tomorrow, back they go into their little drum to turn and turn for another 14 days. I shall try to remember to post more pictures, and then finally in 3 more weeks the jewelery and keychains the boy will make with the included accessories. Looking forward to it!
