Hi everyone,
I need help please on Alum crystals. On most web sites they say you can buy Alum from your spice section in the supermarket or chemist.
But is it the same as using Aluminium Potassium Sulfate? (Potash Alum)
Thanks
Julz

Alum Crystals
I use Aluminium Potassium Sulfate (Potash Alum) when ever i am making crystal that ask for Alum. Our teachers said it is the same. They make great crystals, just make sure that they heat the solution first. Also if you are making crystal with this add some food colouring to make different colours and the Junior classes love this.

Hi Mary,
I usually make up a Super Saturated solution of Alum and have them cool very slowly..
This makes for some good tetrahedral shapes and sometimes Rhombic.
See you soon,
