Often used as a mordant when marbling to make the paint stick to the fabric or paper. Also used as a mordant for Natural dyes. Ours is a salt of aluminum known as aluminum sulfate.
Double sulfate of aluminum and potassium used as a mordant.
Salts used to prepare skins for binding, making them soft, malleable and white in color.
usually in crystal or powder form; has strong astringent properties; used in stypic sticks, popular with men who often nick themselves shaving.
double salt of aluminum sulfate with sodium, potassium, or ammonium sulfate (i.e., AlM(SO4)2, where M = Na, K, or NH4). [Black, Lavoisier
the term used in papermaking for aluminium sulphate.
Added in the drinking water treatment process causing particles to clump together and fall to the bottom of the settling basins.
Also called hydrated aluminium sulphate or papermaker's alum. A papermaking chemical that's typically used when adding rosin size to pulp, alum imparts water-resistant properties to paper. In practical terms, it keeps paper from clinging to the presses.
an astringent used in antiperspirants to prevent irritation from aluminum chloride.
Potassium aluminum sulfate, or ammonium aluminum sulfate, used especially as an emetic (i.e., an agent that induces vomiting), an astringent (i.e., a substance that contracts tissues), and a styptic (i.e., a substance that tends to check bleeding by contracting the tissues or blood vessels).
alum and was used as an astringent in mouthwashes and gargles, dermatological preparations and as the styptic in styptic pencils.
Used in rosin sizing to hold paper fibers together, it is an astringent, crystalline substance. It is responsible for introducing acid into paper.
aluminum sulfate, commonly called Floc. Used to help clarify water. Causes small particles to join together so they can be trapped in filter. Alum lowers the pH of the water.
a "double salt" that occurs naturally in various minerals and is used to cause pollutants to settle out of water. Most are white crystals. The most common alums are potassium sulfate, sodium sulfate and ammonium sulfate.
Aluminium sulphate (Al2(SO4)3): the most widely used coagulant throughout the world.
Aluna Alun The name used for aluminium sulfate in the paper industry. Used for example in initial sizing of paper.
A salt containing two types of metal ion, one of which has a single positive charge (such as Na+ or ) and the other of which has three positive charges (such as Al3+ or Fe3+). An example of an alum is sodium aluminium sulphate, with the chemical formula NaAl(SO4)2. The sodium ion and aluminium ion together contribute 4 positive charges, and these are balanced by two sulphate ions ( SO42-), each of which contributes two negative charges.
aluminium sulphate, added to gelatine in the sizing of paper to stabilise the gelatine.
An alum is a double salt comprising a sulphate salt of a monovalent element, with the sulphate salt of a trivalent element. The most well known example is potash alum (aluminium potassium sulphate) KAl(SO4)2.12H2O which is used to clear murky water.
An aluminum sulfate compound used to cause suspended particles in the water to congeal into filterable masses or to settle to the bottom of treatment units.
aluminum salt used as flocculating agent.
a chemical, aluminum sulfate, added to drinking water to neutralize negative charges on particles so that they will clump together and settle more rapidly; also added to wastewater to remove phosphorus by precipitation.
A type of immune adjuvant (a substance used to help boost the immune response to a vaccine). Also called aluminum sulfate.
A salt used to prepare a skin for binding, rendering it soft, flexible, and white in colour. See also tawing.
A papermaking chemical used for precipitating rosin size onto pulp fibers to impart water-resistant properties to the paper. It is also called aluminum sulfate.
aluminum sulfate: a chemical, which is mixed into water to cause particles in the water to clump together so they can be removed
The common name for aluminum sulfate, a chemical used in the coagulation process to remove particles from water.
a potassium aluminum sulfate or ammonium aluminum sulfate used as an astringent or as an emetic.
Alum is a double sulfate of a trivalent metal such as iron and a univalent metal such as potassium or sodium. Alums are widely used in industry as clarifiers, hardeners, and purifiers and medicinally as topical astringents and styptics.
Potassium aluminum sulfate. Jewellers' rouge Ferric oxide.
A potassium aluminum sulfate used especially as an emetic.
An astringent crystalline substance used in rosin sizing to hold paper fibers together; responsible for introducing acid into the paper.
In the papermaking context, alumina sulfate: A12(SO4)3 ù 14H20, A12(SO4)3 ù 18H20, or a mixture of these hydrates. The increasing use of alum in papermaking since the 17th century (especially since the introduction of alum-rosin sizing in the mid-1800s, and the substitution of aluminum sulfate for the milder potassium aluminum sulfate about the same time, has been seen as the principal cause of deterioration of books since 1850.

A sulphate of aluminium and potassium used in medicine to stop bleeding.
a chemical (aluminum sulfate) used to clarify water, by creating a gelatinous precipitate, that has to be vacuumed to waste. Technique is called flocculation.
A common name for aluminum sulfate, used as a coagulant.
Aluminum sulfate, commonly called floc, is used to help clarify water. Causes small particles to lose suspension so they can be vacuumed. Alum lowers the pH of the water (see Floc).
A double sulphate of aluminium and potassium.
Aluminum sulfate (an acid salt) used in the paper making process.
an astringent that's often used in after-shave products to treat nicks or razor cuts caused by shaving.
A papermaking chemical that imparts water-resistant properties to paper and keeps sheets from sticking to the presses.
The common name for aluminum sulfate [Al2(SO4)3 14H2O] which is often used as a coagulant in water treatment.
An aluminum sulfate compound, used (for pools) to cause suspended solids in the water to congeal into filterable masses (flocculate).
