Alum

[drathgeb]

I ordered alum off of Amazon and it was beaten up so bad during shipping it was unusable. Then I was at the grocery store and found alum chunks for about 90 cents. Is this the same alum that I paid $12 for online?

Could be.... my first alum block came in an Edwin Jagger wrapper which made it worth over $20..... the last two orders I've made online came with complimentary alum blocks in the package. I don't know exactly what your local grocery store is selling, but there's a good chance you can get the same product for alot less than $12 I suppose.

It usually is the same thing. I bought the expensive kind before but went to the Indian goods store and found they had $2 blocks of the alum minus the nice case. Its all the same as long as its alum.

You can melt the beat up alum in a double boiler and pour it into a glass bowl or sumthin...so I heard. No personal experience tho.

Melting point is ~90*C, so you could use a double boiler system to keep the heat regulated. I haven't tried it, but I know it's possible.
