Product Description Product DescriptionCupels are magnesia or bone ash cup shaped containers used in assaying to separate precious metals from base elements such as lead. They operate as a "differential filter" and are porous to metal oxides, but not metals. Used in an oxidizing atmosphere, base metals are oxidized and are absorbed into the cupel. Since precious metals do not oxidize, they are not absorbed and are left on top of the cupel for weighing or further analysis.The lead button for cupellation is typically generated in the crucible fusion from the fire assay process, but can also be produced by a scorification assay, or a bullion assay where the precious metal is wrapped in lead foil.Mgo 93%Cao1.40%Sio21.50%Al2o3 2.20%Fe2o30.80%Tio20.20%K2o0.20%Others0.70%Density 2.3g/cm3Lead oxide absorption rate70%-75% of the dead weight of cupelPrecious metal recovery rate99.50% Bulk density g/cm32.01Sio2 %66.26Al2o3 %28.81Fe2o3 %1.57Cao %0.1Mgo %1.25Cupel SizeHeight"H"-mmOuter Dia"D"-mmBase Dia"D2"-mmCup Dia"D1"-mmCup Depth"H1"-mmRidge Height"H2"-mmYN-F21724191884.5YN-F3202620235.58YN-F4A2227202467.5YN-F42229232468YN-F52635262786.5YN-F6-2626403031.211.86YN-F6-2929403031.211.89YN-F732403031.211.812YN-F7-135403031.211.815YN-F7-2324030321512YN-F827.144.334.634.28.59YN-F8-1354537381313YN-F8-2354537331215YN-F8-3404434381413YN-F930514340115YN-F9-134391514YN-F1030.26049.752.611.511YN-F114456.848.847.814.810YN-F147011088802414 Company ProfileWay of shippingOur AdvantagesFAQQ1: How can know your quality?We can send you samples or sample material for you to check or test.Let our physical samples speak loudly.Q2:Are these samples free of charge?Some standard small samples are free.If same as your requirements,we will just charge for mould to support.Q3:If products are not to requirement,how can you do?We will try our best to solove.Meeting your requirement is our mission.Q4:What's the lead time?Normally,for standard items,will ship within 1-10 days.For mass production order,we will finish within 30 working days after we receive payment.Q5:Payment terms:We can negotiate.
