Depends on what you are electrolysing. Fibreglass wont stand up to strong alkali. Thats why I used non-woven polypropylene cloth (reusable supermarket shopping bags! :D ) in my water electrolyser (NaOH electrolyte).

What? ordinary shopping sacks are porous enough to pass ions? I know they turn to shit if you try to reuse them too much but I never thought they could be porous. How did you discover this if I may or should ask?

He's not talking about regular HDPE grocery bags. He's talking about the reusable kind that you can buy in the store sometimes.

MJP is correct. The checkout girl was rather upset when I told her what I wanted them for :D . Thought for a moment she was going to refuse to sell them to me!
