SOMETHING THAT TUMBLED OUT
- Some mud coated rocks that get tumbled
- Washed and one is
- UV illuminated
- Some even Float
Tumbling is the Art of putting Rocks, Abrasive powder and. Water into a sealed container and slowly rotating it for several weeks 24/7... Yes, there are added steps in Dec 2016 worth seeing!!
After several weeks of grinding ( tumbling) there is a muddy mixture of smoothed rocks which must be emptied out of the now un-sealed container and washed as the pictures show.
After inspecting the smoothed rocks, some attract my attention as that single Quartz rock which had a very pronounced UV iridescence, please see the tenth picture.
There are also provided color images of that same rock under three different lighting sources amply outlined in the picture notes.
Then see a small Geode ( that is a nodule of Quartz inside a hard rock ball)
Some geodes are hollow (there is a million year old gas trapped inside)..
After two weeks of tumbling to remove 80% of top rock and weeks more to polish.
You get a fashionable Jewel which can be split into two halves to adorn a young finger
or becoming a striking neck pendant.
This is where some rocks can become jewelry..
Enjoy the visuals.
See That Blue Marble
Well here is a simple gauge to tell you how rough your tumble has been.
The marble diminished size compared to the original bag of them
lets you see how effective your time and tumble grit has had on the slurry.
Don't expect to see the rocks from a first shaping tumble to look this shiny when dry.
You will need to tumble several finer and finer grits to arrive at polished shiny results.
HOLLOW GEODES CAN FLOAT
When the enclosing rock is partially removed by tumbling for weeks, some hollow geodes reveal themselves in a floating expression.
