 — Kaolin clay is used as a base soil due to its uniform composition (low organic content, homogeneity and uniform mineralogy) and low cation exchange capacity [1], [2], [3], [14]. The basic physiochemical properties of the kaolin clay are summarized in Table 1. The pH is measured per ASTM D4972 [25] using a pH meter HORIBA D-54.

The kaolinite content of processed kaolin varies, but is generally in the range of 75 to 94%. Kaolins from different deposits in the UK and from different parts of the world have markedly different properties and the range of minerals associated with kaolin influence its suitability for different applications.

 — In this article, we will explore the diverse advantages of incorporating kaolin clay into your garden, ranging from controlling pests to enhancing plant growth. Gardening enthusiasts are constantly on the …

This is a very complex question with many possible answers. And while each proposed answer has its advocates, no single answer seems satisfactory to all—except one. Almost everyone agrees on one cause of geophagy, inadvertent consumption of air-, water-, and foodborne dirt. Contaminated food, soiled hands, and inhaled dust add soil to our diets.

Insecticidal DE has very low mammalian toxicity, but as a fine dust it can pose a mild inhalation hazard, so the use of a dust mask is suggested. Pool filter grade DE contains crystalline silica that is very dangerous to humans if inhaled, and should never be used for any purpose except as a filtering agent in swimming pools. Kaolin Clay
