Discover The Art of Lapidary

Author: Joe Kanooga

A rock tumbler is a tool commonly used by rock collectors and geologists to polish rocks. It is amazing to see a rough rock transformed into a beautiful gem, just be spending time in the tumbler. This article provides you with rock tumbler instructions so you can use a rock tumbler and make it perform its' magic.

For an aspiring geologist, gemologist, or mineralogist, a rock tumbler kids will enjoy can be both a toy and an educational tool. However, there are many types suited to different purposes, and not all of them will work for an amateur.

A standard rock tumbler kit can be found at most toy stores.
This rock kit usually contains the tumbler along with some rocks, grit, and a few jewelry findings. With proper care, a good rock kit can be used over and over and can last indefinitely. However, the small size and small power of the motor will limit the size of rocks that can be used. Should the tumblers break, it may be difficult to find replacement parts.
More than likely you would be looking at buying a new rock kit.

The type of rock kit available from toy stores includes rotating or rotational rock tumblers. In a rotating tumbler, the rocks fall over and over, rolling around and polishing them as they collide with one another, similar to the way mountain rocks are polished by the steady collision with a mountain stream. It is advisable to choose a rock kit made by a company that has been around for a while in case you need a replacement part.

Vibration (or "agitating") tumblers are higher quality and generally more expensive form of rock tumbler. Instead of physically rotating the rock, vibration tumblers either use ultrasound or spin around the vertical axis. They work much more quickly, one to two weeks, as opposed to about a month for a rotational tumbler. They also maintain the essential shape of the rock, rather than producing a uniformly round rock. So unless you want all of your rocks to have the same basic round shape, you will need to consider a vibration rock kit. They are a bit quieter as well.

Size is extremely important. Rock tumblers are sized according to the weight of the load they can continuously bear. Since it can take a month or more for a rotary tumbler to polish a rock, it is important that the tumbler can handle the weight of the rock. The most common cause of rotor failure or broken belts is an overloaded barrel. Large barrels can hold both large and small rocks, but small barrels can only hold small rocks. This seems logical, but on the day that your tumbler breaks, you will regret purchasing a small barrel!

At the same time, large barrels generally cost more money (no surprise), and you will need to balance your budget against the size and type of rocks you hope to polish.

Once you've chosen and purchased your tumbler, you will also purchase a few accessories for your polishing. You will need Vaseline to seal the barrel against leaks- an ordinary store brand of petroleum jelly is fine. You will also need extra grit, unless of course you want to use the grit purchase as an excuse to buy a nicer tumbler! Keep in mind the time that will be required to tumble (a week or two for vibration or a month for rotational tumblers) and the noise that will be generated by the tumbler. If noise is a concern, you may want to purchase a large cooler to insulate and minimize the sound.

A basic rock tumbler can inspire a future career in the geology or gemology. It can also lead to the purchase of a larger and nicer rock kit! Some children may be satisfied with a simple rotary tumbler as a supplement to their rock collection, while others may seek better tumblers in their quest to collect amazing rocks. Regardless of what kind you get, a rock tumbler will inevitably be an educational and entertaining toy.

When beginning a new hobby, it is important to know where to start. The best place is to get to know what sort of equipment you will require. Hopefully, I can offer you a few tips on the correct rock tumbling supplies.

A tumbling machine is your very first step. This is essential for the rotation of the actual tumbling process. Since different sizes are available, do some checking into which one is appropriate for you.

Next, you need items called "barrels". These are actually what you put the rocks into for the tumbling process. Since they are most often made of plastic and have to be used to tumble rocks over and over, they will need to be replaced more often than the tumblers.

Since the rock tumbling process consists of four steps, you will need one barrel for each step. So, plan on starting with four barrels.

Now, we get down to the nitty gritty. Well, really just grit. Silicon carbide abrasive grit is used next. There are different sizes, but you will only need three to start with. Hardware, home improvement and rock or mineral stores are where to find this.

You will want to get one tub of size eighty, one of size two hundred twenty, and one of size four hundred when buying your grit. Ask for help in the store if you have trouble.

Now we have reached the point when you need cerium oxide polish. When the tumbling is done and all of those rough, sharp edges are removed, you need to put them into a fresh, clean barrel. Then you add the cerium oxide and some water. You know that part of the process when the stones appear to be shiny and a resemble glass? Well, this step is what makes that happen. Since you only need a tiny bit of polish for each batch, you can buy a very small container at first.

Okay, pellets are last. You must have round and plastic pellets. They protect the rocks from damaging each other while tumbling. They get tossed in at the beginning of the process and really help keep chipped rocks to a minimum.

Well, now you are informed as to the basic rock tumbling supplies. What are you waiting for? You should be on your way to the store right now!
