I got a comment on the blog from a guy at Shavex, an Indian company that sells alum bars. I decided to give them a go, found that the minimum order was two bars. Okay. Got the bars quite quickly, BUT: tiny. 55 grams. WAY overpriced. Avoid.

Shavex, has lately stopped producing custom sized alum as our experts have fixed up a single size for Alum. Alum has been found to remain highly consolidated when made in cubes of our current dimension. As a result our 55g (approx.) alum blocks last 2-3 times more than even 100g alum blocks of other Alum Block companies, and is twice as effective with lesser stinging effect.
woodbane said:55g grams of alum is 55 grams, it's density (or I think what is being eluded to should be more correctly termed mass) will be a related to the chemical composition of alum and have a fixed value per molecule.
I'm still smelling :9898:
Creslin said:Isn't density the relationship of mass/volume? If I'm wrong someone please tell me becuase I hate to have incorrect thinking muddling up my brain. You can have two of a substance with the, both with the same mass but they take up different volumes depending on their density.
An example would be pure carbon. A diamond is is a form of pure carbon that has been subjected to tremendous pressure as well as heat. The pressure results in a "compressed" form of carbon. A better example would be water. You can have a certain vollume of water and it will hae a certain mass. If you freeze that water it still has the same mass but now takes up a larger volume. Again, if I am wrong please tell me.
fuerein said:You are correct. Density is the relationship between volume and mass. Hence why I said their "remain highly consolidated" comment sounded like they were making a comment on the density of their block since the "highly consolidated" sounds like it has a greater mass in a smaller equal volume to that of an ordinary alum block.

I can explain how this particular alum block works. On another forum, John Q. Shavex offers a free alum block with the purchase of, and I quote,
an
alum block. Later, we discover that it is a free alum block with the purchase of two blocks.
Apparently, this is the same math used to bring the alum molecules closer together.
There. That should make it clear. As clear as an unmuddied lake. ... clear as an azure sky of deepest summer.....
