Alumn pickle


#1

I use alum exclusively for pickling in our studio. No acids or
other toxic chemicals. It is very simple and safe to use

-you must have a stainless steel pot or a copper pot -put the 1
tsp. of alum in the pot with about 3 cups of water -if you have a
stainless steal pot you must put a few grams of copper in the
pot -you then put the pot on a burner and bring to a boil for
about a minute or two.

Are you saying that the alum/water mixture heated in a crock pot
will not work? Why do you need to put copper in? Further
explanation would be greatly appreciated.

Dear Neda,

I know of jewellers who use alum in a crock pot without any
problem. I myself prefer to use a pyrex dish on a heat proof mat
on an electric burner, because I hate fishing for things in a
crock pot and I like to see the piece that I want to take out,
whilst I leave the last one I worked on, to clean. Quite frankly,
when you considered how cheap commercial alum is, ( there is no
point in buying high qualtiy stuff). ( I pay about Aud $18 for
two kilos. One Australian dollar is worth 56 US cents.) I am
quite happy to use it and change it every week , or sooner if
necessary. Besides which “hole free” clothes are are less
expensive!!

Best wishes

You need to put copper in the stailess steel pot as the process is a
reverse galvanic reaction. If you have a copper pot you need not do
this as the copper molecules plate the inside of the copper pot.
