Abstract

"There are on the market various cupels. Many of the assay-supply firms sell a "manufactured" cupel, presumably made of bone-ash. The great majority of all cupels used, are made of bone-ash in the assay office itself. The object of this work is to compare the losses of gold when the various patented, the various manufactured and the ordinary hand made cupels are used" – p. 1.
