| It hath also the property of rendering them volatile, and greatly facilitates their scorification. |
| Various assays are described and directions given for crucible, scorification, and cupellation tests. |
| The concentration of the button of lead may be effected either by scorification or by fusion in a crucible. |
| If the scorification has been unsatisfactory, the quantity of silver obtained from the slag will be by no means inconsiderable. |
| If these larger cupels are not at hand the larger buttons will have to be reduced in size by a scorification before cupelling. |
| Next pour into the scorification mould, and, after the slag has set, remove it with a hammer. |
