Cupels


   Magnesite cupels that can be supplied packaged for use with either 25 plc or 50 plc cupel forks.

   Standard cupel sizes of 6A, 7A, 7AS, 8A, 8S are available to handle lead buttons from less than 30g up to 75g.



The lead/gold ‘button,’ containing all the precious metals from the original sample is placed into a cupel, a solid cylinder with a shallow depression in the top. When heated to melting point, the cupel slowly absorbs the lead, leaving only the precious metals.


CS Ceramic CO.,Ltd fire assay cupels are manufactured from magnesium oxide to produce a consistently reliable performance.
