Potash alum is another name for potassium alum. Alum is a class of molecular compounds, and included in the class is potassium alum. So, they are not the same thing, but yet very similar in that potash alum is a member of the alum class.
Alum can be separated from a mixture of alum and water through a process called crystallization. When the mixture is cooled or allowed to evaporate, alum will crystallize out of the solution due to its solubility properties. The crystals can then be collected by filtration. This method effectively separates the solid alum from the liquid water.
To make pure crystals of alum from impure alum, start by dissolving the impure alum in warm water. Filter the solution to remove any impurities, and then cool the filtered solution slowly. As the solution cools, pure alum crystals will start to form. Carefully collect the crystals and allow them to dry to obtain pure crystals of alum.

Refer to the National Center for Home Food Preservation (NCHFP) website, it is an excellent source for current research-based recommendations for most methods of home food preservation and includes many tested recipes.
No, calcium chloride cannot be used in place of alum. They have different chemical properties and functions. Alum is commonly used in water treatment and as a mordant in dyeing, while calcium chloride is used for de-icing roads, in food preservation, and as a drying agent.
Hydrated potassium alum appears as colorless or white crystals with a smooth or glassy texture, while the anhydrous form typically appears as a white powder. Hydrated potassium alum can also exhibit water droplets on its surface due to its water content, whereas the anhydrous form does not show this characteristic.
