Why is it called Fossil Shell Flour®?
We use this name to differentiate our products from all other diatomaceous earth products available in the market. Amorphous diatomaceous earth from our deposits is ground until it reaches flour texture. Hence the name Fossil Shell Flour®, flour made of fossilized diatom shells. No two diatomaceous earths are the same. Our diatomaceous earth originates from deposits of fossilized shells of diatoms Melosira Preicelanica which lived in extremely pure fresh water.
Why is this type of diatoms so special?
Its shell is built of amorphous silica. The shape and hardness of the shells affect the quality of the Fossil Shell Flour®. Hardness of the shells prevents them from dissolving in fluids. Holes in the shell walls ensure that they absorb moisture. As a result our flour may be used as anti-caking agent.
What is the difference between diatomaceous earth from fresh water deposits and from salt water deposits?
Fresh water deposits, such as our one, have got stable content of diatoms. Fossilized shells preserve their original tube shape. This shape and resistance of fossilized shells are crucial for the effectiveness of the Fossil Shell Flour®.
What is the difference between amorphous earth and crystalline silica?
Amorphous silica SiO2 occurring naturally is a rare mineral variety that is necessary to every mammal on our planet. Silica changes its form to crystallized form in higher temperatures with volcanic activity or as a result of industrial activities of humans.
Diatomaceous earth containing crystalline silica is used in filtration systems, for example in swimming pools. Fine-crystalline silica is very dangerous when it is breathed in or when it is in the digestive system, as it is not biodegradable.
Diatomaceous Earth Fossil Shell Flour®:
- originates from high purity fresh water deposit
- meets the requirements of the Food Chemical Codex and may be used in food industry
- inflammable, non-toxic
- contains less than 1% of crystalline silica – smallest level of all known deposits
- safety scale according to the Hazardous Materials Identification System (HMIS) (0 – safe, 4 – dangerous): health – 0; flammability – 0; toxicity – 0
- CAS No. 61790-53-2
- WE No. 612-383-7 100
Food-grade amorphous FSF Diatomaceous Earth has been certified by:
- EPA (US Environmental Protection Agency) – as a safe insecticide against crawling insects for indoor and outdoor use
- EPA (US Environmental Protection Agency) – as a safe addition to grains to control mealworm and other pests
- USDA (United States Department of Agriculture) – as an anti-caking agent used in animal feed
- FDA (Food and Drug Administration) – as a food grade product for external and internal use
Depending on their origin, some deposits may contain clay elements in volumes sufficient to block the pores of fossilized shells. In such case, the effectiveness of diatomaceous earth is seriously limited.
We have conducted numerous analyses of deposits other than those of food grade to compare them, and they are a proof that diatomaceous earth in our products originates from the purest fresh water sources.
We also hold certificates confirming that our diatomaceous earth is a food grade product.
