Was the chisel steel treated to be very hard, by heating to red hot and then dropping into a bucket of oil or water? Or was it tempered by heating to a lower temperature for a while and then cooled slowly?

We had a 1.5 cubic gas furnace. Water cooled for temper ‘cause we were in Jr High and would have found a way to set the oil on fire. :)
