The Furnace Atmosphere During the Fire Assay

It has been claimed that the introduction of excess air to the assay furnace during sample fusion can materially increase the gold yield. Testimony by expert witnesses for the defense in recent federal hearings dealing with the dependability of the gold fire assay includes data purported to show this.

There was an outcropping of exposed bedrock on the bank, and it again resurfaced in the river about 25’ away. I decided to start a hole near that exposed bedrock, and pointed the nozzle down into the sand and cobbles.
