In some embodiments, the physical component (6) may be powdered or in particulate form. The physical component (6) includes diatomite. In such products (4), a crystalline silica content of the physical component (6) by weight is greater as measured according to Traditional Methods than as measured according to a method that differentiates between opal-C and cristobalite. The Silica Documentation (8) discloses the crystalline silica content present in the physical component (6) as measured according to the method that differentiates between opal-C and cristobalite. The method of preparing the product (4) may include analyzing the physical component (6) for crystalline silica content using an LH Method to determine cristobalite content and preparing Silica Documentation (8) based on the results of the LH Method.

The present invention provides for an oil pad having an oil absorbing medium which is formed or compressed to a particular shape. It is intended that such oil absorbing pad can be placed over an oily spill, or in a container containing oil, whereby the formed shape optimizes oil absorption by wicking oil to the interior of the pad, being sufficient to absorb and retain large volumes of oil, or to expand as oil is absorbed to expose one or more potions of the pad to the oil volume to be absorbed. The inventive oil absorbing pad reduces waste, does not create a mess when disposing, and effortlessly absorbs oil from an oily surface.
