Types of Alum

Potassium Alum: Potassium alum is also known as potash alum or tawas. 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.

Uses of Alum

Alum has several household and industrial uses. Potassium alum is used most often, although ammonium alum, ferric alum, and soda alum may be used for many of the same purposes.

Alum Projects

There are several interesting science projects that use alum. In particular, it is used to grow ​ stunning non-toxic crystals. Clear crystals result from potassium alum, while purple crystals grow from chrome alum.​​

Alum Sources and Production

Several minerals are used as the source material to produce alum, including alum schist, alunite, bauxite, and cryolite. The specific process used to obtain the alum depends on the original mineral. When alum is obtained from alunite, the alunite is calcined.

Old methods for crisp pickles

If you use any or all of the modern methods above, you probably don’t need any of the older ways of helping pickles to stay crisp. Today’s home canning authorities all advise that we use the newer methods listed above from a practical point of view: they feel it gives very good results with the least amount of futzing.

History

Here’s some advice from the Kerr company in 1948 on how to get your pickle crisp:

Newell branded (Ball and Bernardin) calcium chloride

The Newell Corporation, through its Ball and Bernardin brand names, sells it in green plastic canisters under the name of “Pickle Crisp ® .” Unlike their other pickle mixtures, their Pickle Crisp is a pure ingredient (pure Calcium Chloride) with no added salt or extra flavourings, etc. It is a coarse powder consisting of small, white round balls.

Other brands

As of 2019, Mrs Wages has launched their own version of this called “Xtra Crunch.”

How much calcium chloride to use

Generally, use about ⅛th teaspoon per ½ litre (US pint) jar; ¼ teaspoon per litre (US quart) jar.

Other uses besides pickles

Some people advise that if you want to try calcium chloride with fermented pickled products, add it into the jars when you are actually canning the pickles or sauerkraut, not into the vat during the fermentation process.

Can give a bit of a salty taste without the added sodium

In addition to crisping up pickles, calcium chloride can also give a bit of a salty taste, while not adding any sodium to your food.

Use as a pre-soak

In the first incarnation of Pickle Crisp (see History below), Ball advised that you could use it as a pre-soak.

Storage

Store your calcium chloride / Pickle Crisp in a very tightly sealed jar to keep all moisture out, or it will clump because it is very “hygroscopic.”
