people call fluxes because they are added to ores not only for assaying but also for smelting Agricola p 232 All silver ores need to be fluxed for smelting6 In Pliny s day when almost all the ore smelted was high grade the addition of lead or lead ore galena Assaying and Smelting We will go into fluxes later The ore and flux is placed in a clay crucible and heated at about C or F for about an hour or until it is a thick homogeneous liqu For example If we are assaying a sample of ore for gold we must first divide all the ore as well as possible by grinding it Usually 30
