Why was alum so important?
Alum was one of the most important chemical compounds involved in the dyeing of textiles and the manufacture of organic lakes, used in painting and illuminating techniques. It acts as a siccative agent in the preparation of oils and varnishes.
Alum was used not only as a mordant when dyeing textiles, wood and bone, alum was used to precipitate some pigments. In the papyrus, the mordanting process is explained in several ways.
It can be used as a fire-retardant. To remove body hair, alum can be used. In the case of non-serious minor cuts, alum can be used in styptic pencil to stop bleeding. For industrial purposes, it can be used in manufacturing deodorants.
It is aluminum potassium sulfate. This is the type of alum that you find in the grocery store for pickling and in baking powder. It is also used in leather tanning, as a flocculant in water purification, as an ingredient in aftershave and as a treatment to fireproof textiles. Its chemical formula is KAl(SO4)2.
Alum in Ancient Rome
The Romans used alum both as a mordant – to fix dye to cloth – and in the preserving of leather. The colours used in clothing reflected the status of the owner and the depth of colour and colourfastness was important.
Alum and green vitriol (iron sulfate) both have sweetish and astringent taste, and they had overlapping uses.
Generally, an alum block is used after shaving to soothe the skin, prevent the spread of bacteria, and reduce bleeding associated with minor nicks and cuts. It can also be used to prevent some of the more annoying side effects of shaving, such as razor burn and ingrown hairs.
Reduces Sweating
Alum can also be helpful in controlling sweat. If you sweat excessively, bathe in alum water and you will notice the difference soon after. It is also present in most of the deodrants these days as it has anti-bacterial properties that can help get rid of bacteria that causes bad smell.
Alum's toxicity to humans
Aluminum sulfate is fairly non-toxic, with acute and chronic oral LD50 both greater than 5,000mg/kg (5). However, alum can still cause irritation, burns, and respiratory issues. If inhaled, it may cause headaches, nausea, and respiratory irritations.
Do not drink it: as it can make you nauseous. For bleeding gums, weak teeth, and dental caries: Make a paste of one gram of alum, a pinch of cinnamon and some rock salt.
Is alum the same as baking soda?
Alum can also be used as a chemical leavener in the home. It's often used as a reactant in baking powders alongside baking soda. Complete answer: Alum powder and baking soda are not the same thing.
Alum powder soothes the burning skin and brings relief. It also helps in diminishing hair growth if you use this for a long time.
Alum has astringent and hemostatic properties. Alum promotes tissue contraction and decreases the size of the wound. It promotes healing by reducing pain and inflammation.
The informal word alum refers to a graduate of a school, such as a high school or university. It's a shortening of alumnus or alumna. In Latin, alumnus specifically refers to a male graduate, and sometimes this distinction is carried into English, with alumna being used to refer to a female graduate.
Alum is considered to be helpful for tightening the skin. Plus, it has astringent properties that remove excess oil from the skin, which is a major cause for acne or pimples. When mixed with glycerin, this toner can work effectively to improve the skin.
Yes, alum is edible. Potassium alum is an active ingredient in baking powder.
Food Grade Dry Alum is white in color and is available in powdered and ground forms. Applications for Alum include, pickles, relish, puddings, soft drinks, beer, canning, sugar beet liquors, wines, liquors, cake mixes, cheeses and food chemicals.
To apply as deodorant, simply wet the top of the alum stone and rub it onto your skin as you would any deodorant. Smooth it onto your underarm area until most of the water is absorbed, to create an invisible salt layer. The secret to making the crystal deodorant effective is to make sure you're applying to clean skin!
It acts as a hemostatic agent, allowing the blood clot to form. The high ionic strength promotes flocculation of the blood and the astringent chemical causes local vasoconstriction.
Alum block: After shaving, rinse the skin with cold water, then wet or soak the alum block in cold water. Run the block over the skin and allow the residue to remain in place for a few seconds before rinsing. Then apply moisturizer or aftershave.
Does alum remove odor?
Alum addition was effective in reducing odors in anaerobically digested biosolids. Addition of 4% alum to anaerobically digested liquid biosolids prior to dewatering resulted in a 60% reduction in the peak odor concentration in the laboratory dewatered cake, relative to the control sample.
Epsom Salts contains magnesium sulfate (10%) and Sulfur (13%) and can safely be used as bath salts for treatment of skin disorders. On the other hand, Aluminum sulfate, when mixed with water, forms Sulfuric Acid, a highly toxic solution, whose vapors can irritate the eyes, nose and respiratory system.
Just grind some alum powder and then make a paste using some rose water. Apply this paste on the hair and let it dry, after which you can wash it off with normal water. Do this every alternate day, for at least two weeks, and you will see the difference.
Alum is used as the acidic component of some commercial baking powders. It's also an ingredient in baking powder (responsible for the faintly metallic taste). In recent years, alum powder has become increasingly difficult to find because it is toxic to humans if consumed in large quantities (more than 1 ounce).
Alum powder also called Fitkari or Phitkari has amazing skin lightening properties and it helps fade acne scars and dark spots well. Alum powder also has anti bacterial properties making it very effective for not only skin lightening but also for treating many skin problems.
These are available in the range such as Alum Bleaching Agent and are used in the cleaning applications in the industries and at homes. Apart from this, this Bleaching Powder is offered to the clients at the reasonable prices.
Bnyan et al (2014) reported that alum has antibacterial effect. They examined different concentrations of alum by agar well diffusion method against four bacterial isolates including S. aureus, S. epidermidis, E.
Borax (Sodium tetraborate) is used as a cleaner in many parts of the world and may be purchasable in supermarkets or home handyman stores. Boric acid on the other hand is used as a toxic pesticide. (Sodium tetraborate is a salt of Boric acid). Alum is Aluminium Sulfate.

Baking soda does not contain aluminum.
I even called the Arm and Hammer (the “famous” baking soda company) to double check, and they stated very definitively that their baking soda is 100% sodium bicarbonate and contains zero aluminum.
Is alum anti aging?
Helps tighten the skin
The skin starts sagging with age and alum can be used to tighten it. For this, use a pinch of alum powder with one teaspoon of egg whites and rose water. Now, apply it to the face and let it dry.

Once aluminum was discovered and isolated by scientists in the mid-1800's, it was still exceedingly rare; so rare that it was deemed one of the precious metals and was extremely valuable. A precious metal is defined as a scarce, naturally occurring metallic element that has a high economic value.
Why was aluminium only discovered in the 1800s?
So, why was it not discovered sooner? The main reason is that aluminium never occurs naturally in metallic form. Aluminium is found in most rocks, clay, soil and vegetation combined with oxygen and other elements.
Aluminum is the most abundant metal on Earth, and one of the cheapest to buy. But it used to be more valuable than gold. Aluminum is the third most common element in the Earth's crust, but it also bonds easily with other elements.
Platinum is generally valued higher than gold. This is because platinum is rarer than gold, has a higher density and is purer.
In the mid-1800s aluminum was more valuable than gold. Napoléon III's most important guests were given aluminum cutlery, while those less worthy dined with mere silver; fashionable and wealthy women wore jewelry crafted of aluminum.
In North American residential construction, aluminum wire was used for wiring entire houses for a short time from the 1960s to the mid-1970s during a period of high copper prices.
While Hans Christian Oersted is acknowledged as the first to isolate aluminum in 1825 in Copenhagen, Denmark, the eminent German chemist Friedrich Wöhler is generally regarded as the first to secure a pure sample of the element by chemical reduction in 1827.
