carbon arc gouging electrodes

Probably a daft question but can I use these rods for electrolysis? Thanks

I have never done so but I believe it is possible. I was considering getting some for a project and removing the copper. But I ended up changing elctrode material completely.

I don't see why it wouldn't work. As long there is no binder in the carbon, you're fine. The problem with binders is seen with the electrolysis of pencil leads (although that's not the allotrope of carbon you're talking about) which makes an incredible mess.

These electrodes can easily be obtained via eBay. I got 10 8mm rods of 30cm long for $20. They work fine for electrolysis of aqueous solutions and molten salts is my experience.
