A rock tumbler is a device that uses a tumbling technique to polish rocks. The machine is able to mimic the forces of nature to polish stones until they are smooth and shiny. Unlike nature though, rock tumblers usually only take a couple of hours.
Most of the devices are [link widoczny dla zalogowanych] made up of [link widoczny dla zalogowanych] a rotating barrel that is sustained by a tiny battery. Once it is filled with little rocks, the barrel then starts to spin quickly. The [link widoczny dla zalogowanych] resulting movements are able to mirror a river and dramatically change the rock's appearance.
Most types of rock tumblers are the small personal use [link widoczny dla zalogowanych] kinds that are sold in hobby shops. They are primarily for recreational use such as jewelry making and gemstone collecting. These versions typically come with a number [link widoczny dla zalogowanych] of roughed up rocks and pre-measured packets of smoothing grit.
Usually the packets contain harder than sand, silicon grit which can enable the tumbler to quickly smooth and polish the barrel contents. The initial [link widoczny dla zalogowanych] erosion is due to the hard grit that is poured into the barrel. [link widoczny dla zalogowanych] A fine sand and lighter grit are [link widoczny dla zalogowanych] added in later to complete the whole process.
A titanium [link widoczny dla zalogowanych] dioxide polish is used in order to turn a smooth and polished rock into a beautiful gemstone. Much like the carbide grit, [link widoczny dla zalogowanych] it is poured in the barrel which is then turned on for a period of time. It's not a step that is necessary, but doing this results in prettier and shinier stones.
Gemstones created by rivers naturally are nice but rock tumblers can create the same pretty effect [link widoczny dla zalogowanych] in less time. People who use them are able to create gems for displaying or jewelry making quickly. The device also gives geology enthusiasts and children chances to [link widoczny dla zalogowanych] appreciate and experience this hobby from the comforts of their own homes.
