Diatoms b/w Diatoms

Diatoms

Diatoms, a type of algae, are found floating in the phytoplankton of the seas. Their cell walls contain silica. When diatoms die they sink to the sea floor. Their soft parts decay and the silica remains. Over time the pressure of the seawater pushes the silica together to form one large layer. This silica is mined and used as an ingredient in abrasives and polishes.
