What Is A Rock Tumbler?

So rock tumbler is the machine that you use to smooth and polish the rocks especially jewelry, craft, and lapidary hobbyists. It allows you to discover the hidden beauty of rocks as well as minerals starting with a rough piece of rock. The most popular rock tumblers come with a barrel that is loaded with rocks, water, and abrasive grit.

You place the barrel on a motorized machine that rotates the barrel to tumble the rocks that are inside. As the rocks tumble, they grind against one another with particles of the abrasive grit caught between them. This will wear the sharp edges off of the rocks then smooth their surfaces. Rotary tumblers are the type that operates this way, and they are quite common.

Just like sandpaper, the grit has the label of fine, medium, and coarse. In coarse grit, you typically tumble the rocks for one or two weeks and one week for the other two. Once you finish the process, you will see the transformation of the rocks into unique and beautiful polished stones. There are many purposes that you can use rock tumblers for such as:

    Jewelry making
    Holiday decorations
    Vase or planter filler
    Various craft making

Rock Tumbler Types

    Rotary Tumblers: are so common, and they are perfect for beginners to start with. This type of tumbler simple knocks off the edges, shape, and smooth out rough rocks during the coarse grind stage. Normally, rotary rock tumblers will change the shape of the rocks and turn them around.
    Vibratory Tumblers: are ideal for fine polishing rocks that you have already shaped. The thing is this vibratory rock tumbler will not shape your rocks as a rotary tumbler does. It is more for polishing the rocks while maintaining the same shape and angles that they have. You should also use it if you want to speed up the tumbling process after you shaped your rocks.

Other Use Of Rock Tumblers

Apart from rocks, you can also use your rock tumblers for some other objects as well such as:

    Coin: Just throw the stained and rusty coins in the rock tumbler for a nice and clean shine. Make sure the coins are modern coins so that they will not lose their values. Also, remember to never mix copper and zinc metals together as well as silver.
    Glass: Sea glass, to be exact. You should stick to a thick glass-like the kind in stained glass windows or landscaping glass. You have to cut down on the time in each stage especially stage one and two to delicate the process.
    Shells: You can also tumble seashells in a rock tumbler as well, and you should pick the thick ones. However, you will have to change the process a little because shells are less tough than rocks. You should skip the course grit stage, and fill your barrel up as much as possible by using as much filler as you can.
