Where can I find Graphite Electrodes/Rods?

A warning about using salt as an electrolytic with water though, chlorine is given off.  If you stick with small currents for testing, this shouldn't be a problem; but I wouldn't use salt period, not in conjunction with graphite electrodes, it's just not a good idea.

it also leaves sodium-hydroxide in your tank, which over several cycles can become caustic.

I get all of mine out of dead batteries.
single-cell they are in the center, small ones.
a 9-v has 6 of them, small ones.

the square-rectangle, 6-v batteries have great, large electrodes in side them.
these I used many times in electrolizer units (H2O), several battery experiments,
electroplating/unplating units, etc.
They are a carbon (graphite) powder, with an electrically conductive glue-like binder, that holds their form.
they are stable in most conditions and do not corrode.

Yo uso los carboncillos para dibujo, he podido alcanzar los 10.000º C.

charcoals for drawing, I use crayons for drawing, I could reach 10,000th C
