Bentonite is an absorbent aluminium phyllosilicate generally impure clay consisting mostly of montmorillonite, (Na,Ca)0.33(Al,Mg)2Si4O10(OH)2·nH2O. Two types exist: swelling bentonite which is also called sodium bentonite and non-swelling bentonite or calcium bentonite. It forms from weathering of volcanic ash, most often in the presence of water. Bentonite expands when wet - sodium bentonite can absorb several hundred percent of its dry wei ...

Diatomaceous earth - Filtration. The most common use (68%) of diatomaceous earth is a filter medium, especially for swimming pools. Diatomaceous earth has a high porosity because it is made of microscopically small coffin-like hollow particles. It is used in chemistry as a filtration aid to filter very fine particles that would otherwise pass or clog the filter paper. It is also used to filter water and other liquids such as beer. Diatomaceous earth - Abrasive. The oldest use of diatomite is as a very mild abrasive and for this purpose has ...

Whether done by hand or with a paper machine, the paper making process has three simple steps: Paper - Preparation of the fibres. The material to be used for making paper is first converted into pulp, a concentrated mixture of fibres suspended in liquid. The source of fibre is often natural (softwood, hardwood, etc.) or recycled (old corrugated boxes, newsprint, mixed office waste, etc.). When natural materials are used to make paper,it is essential to break down the lignin inside of the cell walls. ...

Please remove this notice after the article has been expanded. Details are on this talk page or at Wikipedia:Requests for expansion. Because diatomaceous earth forms from the remains of water-borne diatoms, it is found in proximity to either current or former bodies of water. Diatomaceous earth is generally divided into two categories based upon source: freshwater and saltwater. Freshwater diatomaceous earth is mined from dry lakebeds and is characteristically low in crystalline silica content. Saltwater diatomaceous ea ...

Paper made in the west since the industrial revolution has been almost exclusively wood based, except for a few specialist papers such as banknotes. However, at least one company (Cloudy Bay Cotton) has recently tried to introduce cotton based tissue papers to westernised countries as an alternative to wood based ones. Their reasons for doing this are that the cotton based tissue papers are less abrasive, less likely to cause allergic reactions, and far more environmentally beneficial than wood papers, being made from renewable materials (th ...

The word paper comes from ancient Egyptian writing material called papyrus, which was woven from papyrus plants. Papyrus was produced as early as 3000 BC in Egypt, and then in ancient Greece and Rome. Further north, parchment or vellum, made of processed sheepskin or calfskin, replaced papyrus which requires subtropical conditions for growth. In China, documents were ordinarily written on bamboo, making them very heavy and awkward to transport. Silk was sometimes used, but was usually too expensive to consider. Most of the abov ...

The absorbent qualities of diatomaceous earth can result in a significant drying of the hands if handled without gloves. The saltwater form contains the highly crystalline form of silica resulting in sharp edges. The sharpness of this version of the material makes it dangerous to breathe and a dust mask is recommended when working with it. The type of hazard posed by inhalation depends on the form of the silica. Crystalline silica (silicon dioxide) poses a serious inhalation hazard because it can cause silicosis and can eventually lea ...
