If I was to electrolyse a hot sodium chloride solution I'm pretty sure a copper electrode would react to make copper chloride. Whereas I would have used graphite electrodes if the solution was cold, this reaction should produce sodium chlorate which can obviously be quite reactive with organic compounds. The only other thing I have in the house is some spare silver. It's no platinum but it is more inert than copper. Would silver or graphite be safe, or should I only attempt this with platinum?

Silver is not that noble, especially in the chlorides solution it can be relatively easy oxidized to AgCl.

What are you actually trying to do here?

Neither the oxygen gas nor sodium chlorate in aqueous solution, even at 100 degrees, should start a fire with your graphite electrode. Graphite requires very high temperatures to ignite.
