Corrosion on steel cathodes in cells I have run always occurs just above the surface of the liquid. I have used PVC sleeves (just a small PVC pipe) filled with hot glue to cover this area and extend below the water. It solved, well minimized, the problem for me. I'm sure something similiar will work for you.

I've found treating the graphite (welding) electrode with linseed oil reduces their rate of wear significantly. I just soak for a few days, wipe off the excess and leave to dry for about two weeks before using. Graphite can be easily removed from the solution using a funnel with a few cotton balls stuffed into the bottom. I use a 2 liter soda bottle with the bottom cut off and a few holes drilled in the cap. 3 cotton balls stuffed into the neck will remove all the graphite and leave you with a crystal clear solution. It takes a while to filter through so support it well and just leave it over night. These are all pretty common solutions I found online, hope they help.

If I remember correctly, raw linseed oil doesn't dry. It just stays an oily wet coating.

I've only ever seen the boiled linseed oil used as a magnesium coating and that's in a warm pan while stirring to keep it from clumping together as it dries.

Also, check the ingredients. Linseed oil is quite often not what it says. If the ingredients say it's 100% boiled linseed oil it is suitable for your purpose.

Try a ceramic supplier. In the U.S. at least, most ceramic suppliers have it for about $2.50 a pound.

A little flour, a little KBrO3, a little sulfur...

Poof! Instant toast.

Might be quite a seller.

There are very good instructions for making your own potassium bromate here:

I followed these instructions using a platinum anode and was very successful. It's a fantastic experiment, I watched the nice red bromine form around the anode and flow to the bottom of the vessel, captivating! Crystals of KBrO3 started forming soon after.

I haven't tried using any of it yet but I'm looking forward to a few experiments.

This hasn't been banned in the US for use in breadmaking (it should be) I did see it on a list of ingredients for bread recently.
