The post Product Review: Cut That Agate- Speedy Tumble Rapid Refil Kit – Tumble Stone Polish Kit appeared first on Where to Find Rocks.
]]>Speedy Tumble is a product released by Cut That Agate that provides the rough material and everything you need to tumble a wide variety of stones to a high, professional looking finish in under 1 month time. The only thing not provided are the tumbler itself, water, and optional Ivory soap. In essence, it is the fast food of tumbling- an inexpensive, highly consistent product that can be made in a comparatively short time. Unlike fast food, the quality of the product is great and I am very satisfied with the fact that there were probably over 50 different kinds of rough in my assortment. You get 4 pounds total. Speedy Tumble also includes a bag of one pound of premier material too. I think my bag had some almandine garnet. I think it’s amazing what they give you for only $30!!
To test Speedy Tumble, I decided to take the minimal amount of time it instructed to tumble for. So from start to finish, three weeks and one day total time. For my tumbler, I decided to use the most convenient option I could find. That meant I decided to take a trip down to my local Harbor Freight and purchase their Chicago Electric 3lb. rotary rock tumbler. It proved to be surprisingly well made, rigid, and perfect for getting the results I desired. Definitely a surprise.
I decided to leave some headspace in the tumbler barrel, and filled it about two thirds of the way with stones from the set that I lightly prewashed. It’s a bad idea to totally fill the barrel, so the stones can move freely and let the grit work them.
I added about 3.5 tablespoons of 400 grit, added some water, sealed the drum, released pressure after 3 hours, then tumbled for one week uninterrupted.
One week later I opened the barrel, placed the rough in a strainer and carefully rinsed off the grit. The material is looking nicer!
Getting more tumbled! I washed this material well and then added about half the envelope of cerium oxide powder and more water.
After a week with cerium oxide, I washed the material well and added a small chunk of Ivory soap and tumbled with a little water to get a higher gloss. There you have it! It’s finished! Let’s take a look:
Here is a handful of the beautifully glossy finished product. Ready to go for a craft project or just to enjoy!
Summary: Overall I really like Speedy Tumble and I think the value is amazing. Not only do they do the dirty work for you, but they include the grits you need to finish the job. You get a ton of material and the quality is great. I found many semiprecious stones in my assortment including amethyst, rutilated quartz, agate, sodalite, and turquoise. The only thing I can really criticize is I wish the premier material was something a little more colorful, but I can’t even really complain because of how well executed everything else was. Great job on making an interesting product for all ages, Speedy Tumble

]]>But, you never know how much you miss something like a good UV light until it is gone. There are just so many things a UV light helps with when checking out minerals. From the visual identification to seeing if a purchased specimen is glued, a good UV light pays for itself, quickly.
I was excited to read about the improvements to UVTools.com handheld Lamp, an all in one unit with a long wave bulb and a strong short wave bulb powered by 6 watts, a decent output, for just under $100. The kit comes with the light, which requires 3D batteries, a sample of minerals to test the light with shortwave and longwave reactive specimens. Safety goggles and a cd rom with study guides and informative literature complete the package, all in all, it gives a great start to any beginner, while the advanced collector will appreciate the power this highly portable hand held unit produces. I found the LW light to be very bright and it made some of the fluorites in my collection to glow bright white/blue. The shortwave light gives a bright reaction, but typically from a distance of no more than 6 inches from the lamp. It will not light up a hillside, or even a whole flat of minerals, but it is perfect for “one on one” specimen viewing.
Below: Photos of the kit, the minerals that came with it and some UV reaction from those specimens.
You can purchase this UV Lamp from the manufacture, directly at http://www.ultraviolet-tools.com for $99.99.
There were two interesting things I learned by using this UV light. This agate deposit near my house became that much more interesting when I found out that every single piece of agate glows bright green under shortwave light. That means there is a lot of uranium in the area, which is giving the agate that color. Then, a hill over from that agate deposit, at another agate deposit, the brown crust on some of the agates was determined to be an uncommon variety of feldspar, after it was found that these crystals, in micron size, were glowing bright pink, typical of the species. You might wonder, so what, crusts of brown on agate? Well, the sweet thing is that these agates would now glow three different colors, green, pink and orange, sometimes yellow, as well. Three color rocks are what it is all about, so being able to notice the brown crusty bits on some of the agates helps identify them for further UV evaluation! It should be no surprise, those glowing agates include the local petrified palm root and what I like to call “Manix Lakebed Agate” which is a slurry of reeds, roots, rods and roughage from the lake that got silicated into a variety of translucent gel agate in shades of clear to black with red inclusions to a thick jasper-like layered wad of organics in stripes of black, red, cream and white. All of these organic masses were ripe with uranium! Several uranium deposits dot the mountains to the south, UV light is a great indicator of “hot rocks”!
