Is the alum available in the spice aisle the same as the alum that is presses (?) into blocks that we use as a post shave? I wasn't really sure where to post this.
I am trying to learn how much alum is dissolvable in various solutions and using a block is a bit difficult. Not to mention that the alum in the pickling aisle is significantly cheaper.
I know we have some chemists in our ranks.
