When you copy posts, add them in a quote so we see where and who it comes from.

Ok and thanks for your help!

Yes, I will want to sell it, but not yet, but when there are more. Can it be calcined together with the filter paper? I remember that the book says not to calcine together with the filter paper.

I rechecked the book now and it says that you should not burn the paper, no explanation on why, but remember she was writing for jewelers and they try to avoid brittle metal at all cost.

I have had best results cementing platinum and palladium with copper powder, heat, and either stirring with magnetic stirrer or strong air bubbling through solution.
