I have a top loader, gas furnace, too. It seems to take a long time to get up to temp. patience... patience!!
This appears to contain a lot of oxide i.e. iron oxide, would it be recommended to get it up to temp and then shut it off and close up the ports including top to get a reducing atmosphere? I tried charcoal in prior attempts in a mix - it didn't seem to reduce the silver. In theory, the carbon creates co2 which consumes oxygen and reduces the oxide to metal. The paradox with the gas furnace seems to be that you can't get a reducing environment and maintain combustion of the gas.
Photographic paper would supply carbon to that type of silver recovery in a furnace. Maybe too much!
