Depending on the granularity, this powder can have an abrasive feel, similar to pumice powder, and has a low density as a result of its high porosity. The typical chemical composition of oven-dried diatomaceous earth is 80 to 90% silica, with 2 to 4% alumina (attributed mostly to clay minerals) and 0.5 to 2% iron oxide.

A Pacinian corpuscle is a type of touch receptor located in the skin. It is classed as a mechanoreceptor, meaning it is part of the group of sensory receptors that respond to touch and pressure.lthough there are similarities between the two, a Pacinian corpuscle is not as discriminatory as the type of fine-touch mechanoreceptor present in the fingertips, known as Meissner's corpuscle. This type of sensory receptor lies closer to the surface of the skin and adapts only moderately fast.
