About Our Diatomaceous Earth

A Closer Look at Our Diatomaceous Earth

Diatomaceous earth, or DE, forms from the preserved silica shells of tiny algae called diatoms. Our freshwater deposit formed in an ancient lake in Eastern Oregon. Look closely under a microscope and you can see the small openings in the diatoms’ shells—the structure behind DE’s light weight and absorbency.

How We Prepare It
We dry the DE after mining, then process and sort it by particle size to prepare the grades used in our different products.

Our family handles this at our Oregon facility, where we package everything from individual bags to bulk orders. The grade and packaging depend on how the product will be used.

What Gives Our DE Its Useful Properties

Our Freshwater Deposit

Our DE formed from layers of freshwater diatoms that settled in an ancient lake. Today, our family mines and processes that deposit in Eastern Oregon.

Naturally Bright White

Our DE’s bright white color is a natural feature of the deposit. You can see it in the exposed layers of the mountain and in the finished material.

Tiny Shells, Open Pores

Under a microscope, diatoms reveal patterned silica shells with tiny openings. These pores give DE a large surface area in a lightweight material.

Highly Absorbent

DE’s porous structure helps it take up liquids. We prepare absorbent products for uses such as cleaning up spills and managing moisture in animal bedding.

Fine, Lightweight Texture

DE is naturally lightweight. Processing determines the particle size and texture of each grade, so we prepare it to suit the intended use.

For Homes, Farms and Businesses
Our product range puts DE to use in everyday life—from spill cleanup and animal bedding to feed handling, crop protection and labeled pest control.

Each product is prepared for a specific purpose. Explore the range to find the grade and directions that fit your needs, or contact our family for help with a bulk or manufacturing order.
