American Tripoli and Sandstone

What is tripoli?

Tripoli is a highly porous, lightweight material. Due to its porous structure is so soft that it can easily cut with a finger nail and crumbled to a fine powder between the fingertips.

While it may easily be crumbled to a powder, the ultimate individual grains (usually 0.01 millimeter or more refined) are so strong they will scratch steel.

Tripoli, when dry, is exceptionally absorbent. For example, a 4-inch square will absorb one-third of its water weight (complete saturation) in less than 5 minutes. This moisture will dry at ordinary room temperature and humidity in approximately three days.

Tripoli's color is usually pure white, but certain portions can be stained by iron oxide to cream, yellow, brown, and rose-colored.

Limited to a small area in the foothills of the Ozark Mountains in the southwest corner of Missouri and the northeast corner of Oklahoma, within a radius of fifteen miles of Seneca, Missouri, U.S.A., formerly the home of the Seneca Indians, nature has furnished the world one of its most unique non-metallic minerals. No other place on earth on any continent has this material called "Seneca Standard" Tripoli been discovered.

Many non-metallic minerals with chemical analyses similar to "Seneca Standard" Tripoli have been termed "Tripoli," although entirely different in physical particle structure.

Characteristics
Tripoli possesses a natural characteristic of friability, regardless of the size of the particle. The particles will break down, or crumble into smaller particles as it is being applied. Larger Tripoli particles will cut a surface when first applied, and as the particles break down into smaller sizes, they begin to polish, or color the finished item.

It should be remembered that the larger the Tripoli particle size, the more aggressive cut and little polish, or color will be the finished result. The smaller the Tripoli particle size, the less cut and more polish, or color will result.

It should also be remembered that Cream Tripoli is a softer material than Rose Tripoli. Rose Tripoli will always have more cut and less polish ability than Cream Tripoli. Both will produce the same result, but Cream would always be less aggressive.

The item to be buffed or polished will dictate the Tripoli product to be applied. The more aggressive Once Ground Tripoli product will cut heavy metal items such as aluminum bumpers or wheels, where Tripoli R-15 would not even touch the surface. The Tripoli R-15 will provide a mirror finish for a thin brass picture frame with absolutely no cut to the surface.

The above Tripoli characteristics should always be considered before determining which product would provide the desired properties.
