Rock Tumbler Polish

Rock tumbling polish and pre-polish
We offer a variety of polishes for rock tumbling. Most people who have been tumbling for a while have found a personal favorite and use it for most of their work. Others like to experiment with different polishes, looking for a polish that will produce the highest possible luster on a stubborn material. Which one do we use? We use TXP aluminum oxide polish for almost all of our rotary and vibratory tumbler polishing. It produces a great polish and is a lot less expensive than tin or cerium oxide. We also use #61 Rapid Polish for some of our vibratory polishing and for polishing cabochons on a flat lap.

TXP Aluminum Oxide Rock Polish


This is our favorite polish!

TXP Polish



We use TXP Aluminum Oxide for almost all of our rotary and vibratory polishing. It produces a great polish and is a lot less expensive than tin or cerium oxide.

$9.99 for 12oz

$19.99 for 40oz
TXP rock tumbler polish is used for STEP 4 of the rotary tumbling process and the final step of vibratory polishing. This aluminum oxide polish puts a bright finish on agate, jasper, petrified wood and other commonly-tumbled material. We use about two level tablespoons for each pound of rock in rotary tumbling and about 1/2 level tablespoon for every pound of rock in a vibratory tumbler.

Twelve ounce units ship in a resealable plastic tub. The 40 oz (2.5 pound) units are packaged in a durable zip-lock bag and shipped in a corrugated box.

Caution: Do not dispose of used grit, polish or rock slurry down a drain.



Cerium Oxide Rock Polish

Cerium Oxide Polish


A favored polish for use on most types of natural and man-made glass.

$41.99 for 1-Pound
Cerium oxide rock tumbler polish is used for STEP 4 of the rotary tumbling process and the final step of vibratory tumbling. Made into a slurry, it also works nicely on a felt-covered flat lap for polishing cabochons. This is optical grade cerium oxide that produces a great polish. It is a polish of choice for agate, jasper, quartz, and petrified wood. It is a favored polish for obsidian, goldstone, feldspar minerals (such as moonstone, labradorite, sunstone and amazonite).

One pound ships in a resealable plastic tub.

Caution: Do not dispose of used grit, polish or slurry down a drain.

Tin Oxide Polish


A favorite polish used since the early days of rock tumbling.

$44.99 for 1-Pound
Tin oxide polish is used for STEP 4 of the rotary rock tumbling process and the final step of vibratory polishing. It was a favorite polish during the early days of rock tumbling (1960s and 1970s). Lots of old timers still use it today. It does a great job on varieties of quartz, jasper, agate and petrified wood. It works exceptionally well on volcanic glass such as obsidian and on man-made glasses. Many people use tin oxide when polishing soft materials such as calcite, rhodochrosite and malachite on a flat lap.

One pound ships in a resealable plastic tub.

Caution: Do not dispose of used grit, polish or rock slurry down a drain.

#61 Rapid Polish



This is the polish that we use for flat lapping on a felt buff. We also use it occasionally with good results in vibratory tumblers.

$15.99 for 1-Pound
#61 Rapid Polish is a 0.3 micron alpha phase aluminum oxide (synthetic sapphire) particle that was specifically developed for polishing jade by either hand lapping or in vibratory tumblers. It was found to work so well on jade (a very tough stone to polish) that it was tried on other materials. It does a great job on agate, jasper, quartz, petrified wood and other materials in a vibratory tumbler. It is the polish included in our vibratory grit kit.

One pound ships in a resealable plastic tub.

It is inexpensive. It is a residual material produced by weathering of certain siliceous limestones.
