Yellow Feather Jasper Tumbling Rough

Size: mostly 3/8 to 1 1/2 inch pieces

Yellow feather is a multi-color jasper found in Utah. The name "yellow feather" was inspired by dark feather-like markings that cut across a yellowish background. The feathers are usually brown to black in color. The background colors vary, but they are usually in the range of yellow, orange, and tan. The background color of some pieces can be red or brown. (The rough in the photo above was photographed wet to show full color.)

The yellow feather that we offer here is a very nice tumbling rough. The material that we sell is in pieces that range in size between 3/8" (9 mm) and 1 1/2" (38 mm). It shapes well when tumbled in a rotary tumbler and it polishes nicely in either a rotary tumbler or a vibratory tumbler using TXP or Rapid Polish (both aluminum oxide polishes). Other polishing compounds such as cerium, tin or titanium will also produce good results. Photos of tumble-polished stones are shown below.

EASY Rock Tumbling Recipe:

Yellow Feather Jasper (3/8 to 1 1/2 inches)

This yellow feather jasper has been crushed and sized to perform well in small rotary tumblers such as the Thumler's MP-1, A-R1, and A-R2. The size range gives the material a good tumbling action and eliminates the need for ceramic media. Our EASY Rock Tumbling Recipe works well for rough that has a Mohs hardness of 7 and has been crushed to a variety of particle sizes under about 1 1/2 inches.

Recipe for Rotary Tumbling

Tumbling Recipe for easy crushed rough

Coarse Grit Step:
Fill your tumbler barrel about 2/3 full of rough. Then add 2 tablespoons of coarse (60/90) grit per pound of material in the barrel. Add water to just below the top of the rocks. Run the material in coarse grit for 1-2 weeks. One week in coarse grit will give you good results. However, we feel that two weeks in coarse grit gives you much better results.

At the end of all steps in the rock tumbling process, make sure to clean your rocks and barrel to reduce the chance of coarser grit contaminating the finer grit steps..

Medium Grit Step:
Put your cleaned rough back into the barrel. Then add 2 tablespoons of medium (150/220) grit per pound of material in the barrel. Add water until it is just below the top of the rocks. Let it tumble for one week.

Do not pour tumbling mud down the drain
Barrel slurry dumped down the drain will harden like concrete.
Fine Grit Step:
After clean-up, put the rocks back into the barrel using 2 tablespoons of fine grit per pound of material. Again add water to just a little below the top of the rocks. Tumble for one week. The rocks should now be smooth and possibly starting to get a slight luster.

Polish Step:
IMPORTANT: Make sure that your barrel and rough have been cleaned thoroughly. Any grit carried over from a previous step will likely ruin your polish. Place the rough in the barrel with two tablespoons of TXP polish for each pound of material in the barrel. Add enough water to almost cover the rocks and let it tumble for one week.

Burnish If Needed:
Jasper, agate and petrified wood usually take a great polish. However, burnishing this material after the polish step can often improve the shininess of the finished stones. If you would like to try burnishing to see if it improves the look of your polished stones full burnishing instructions can be found here.
