Diatomaceous earth is made up of diatom cell walls, an example of biogenic silica. Silica is synthesised in the diatom cell by the polymerisation of silicic acid. This image of diatomaceous earth particles in water is at a scale of 6.236 pixels/μm, the entire image covers a region of approximately 1.13 by 0.69 mm.
While there are many ways to filter, diatomaceous earth filtration is used as a catcher, which intercepts particles in beer thus improving clarity.

Such systems advance the knife automatically as the surface is removed.
Gone are the heydays of goldsmiths and wheelwrights, but an element of those jobs live on in one form or another. With advancements in technology and science, so come changes in jobs.
When diatoms die and their organic material decomposes, the frustules sink to the bottom of the aquatic environment. This remnant material is diatomite or "diatomaceous earth", and is used commercially as filters, mineral fillers, mechanical insecticide, in insulation material, anti-caking agents, as a fine abrasive, and other uses.
