Chain waxing + graphite question

I have been hot waxing my chains for the last year or so and have been
quite pleased with the results. Before I rewax I take the still cool
"cake" of wax out of the cooker and scrape off the small amount of
sediment (dirt) that has settled to the bottom of the cake.

I have read that some people recommend adding some graphite to the wax
to help increase the life of the chain. However, if I add graphite to
the wax, wouldn't it settle to the bottom of the wax cake after I'm
done with waxing? In that case, wouldn't I remove the graphite when I
scrape off the sediment, defeating the purpose of adding the graphite?
