Joerg,

I think your dark black powder is probably molybdenum disulfide.

My moly oxide, in the container on the left is grey, probably like Ulrike's. The whiter looking stuff on the right is a mixture of moly oxide and whiting in the ratio shown on the note. Powellite (yellow) is in the crucible in the bottom of the kiln.

Phil,

thanks, I get in...User Name and PW work fine....

one question... (I worked almost 30 years for Bayer, but i am not a chemist...(rather one of these stupid commercial guys...)

my Mo is a dark black powder, I bought 2 kg from a retiring potter here in Spain... I guess... this is MoO3...  Ulrikes Mo is grey... , yours seems to be white...  strange, isn't it?

best regards

J
