Medieval Africans Had a Unique Process for Purifying Gold with Glass
What does the material efficiency for the gold look like? Is there room for improvement? Can statistical physics tell us something about purification effficiency? Is there room for improvement?<p>Or is it strictly of historical interest?<p>Can this decrease mercury pollution of the environment, especially by the poorer small scale gold refinement? Or has that already been succesfully replaced world wide?<p>Edit: I have no clue why this got downvoted? I don&#x27;t mind being downvoted, but please don&#x27;t squander an opportunity for interesting discussion?
