using Electrolysis to force a patina

Why would anyone do that though?

a lot of knife makers patina their blades prior to putting handles on them.

This is simply another way of forcing a patina without using chemicals or salts, just good ol electricity and baking soda. I can see a knifemaker doing large batch runs of blades in this setup......
 
Creating hydrogen AND oxygen at the same time is not just hazardous, it will likely produce an explosion.
 
yes, there is a risk, hence the powering down of the arc welder PRIOR to disconnecting the clamps
 
ANY spark could be disastrous.
It will force a patina right through the ceiling!
 
less danger in using a lemon or onion, they usually don't explode.
 
I think its important to state that the amount of hydrogen gas produced in this method is incredibility small, at most your going to get a little "pop" if you DO NOT FOLLOW the very basic directions of shutting the welder down FIRST, as opposed to walking over to the bucket and pulling a clamp off while the unit is still turned ON.

just saying its been a bit overblown.......

Using a 5kW arc welder for electrolysis can produce large amounts of H2 and O2, but they dissipate very quickly.
