Silver.
Silver selenide, more likely - since selenium toner is supposed to react with silver to form silver selenide. :)

Pass the selenium toner through a coffee filter to remove the black precipitant.
Working strength selenium toner can be replenished with fresh concentrate and reused over a long period of time.
