Hi Effie,
From what I understand, you need to store your pickle in either ceramic or glass. Any metal that is not copper used to contain the pickle or remove your items from the pickle will potentially neutralize your mixture, and make it ineffective.
Definitely don't mix up your for cooking pot and your pickle pot - you don't want to end up sick! Although the acid is very mild, it's still best to keep it completely out of the kitchen.
I use this pickle pot - which is perfect because it fits nicely on my workbench, and doesn't get too hot
