I am curious if an Alum Block has a lifespan? Or as long as you've got a piece of stone to hold onto, will it still work?
I have an "Art of Shaving" Alum Block that I bought a few a ago... I used it for a while, put it away and recently brought it out again. It doesn't seem to be changing in size or texture at all as much as I use it... Do they last forever? Or is there just a small amount at a time that gets dissolved off of it?
