Need source for Co electrode or advice on casting Co

Need source for Co electrode or advice on casting Co

(OP)
I need a cobalt electrode.  The only way I have found to buy cobalt is in pieces.  The latest delivery from Spectrum is really small pieces.  I need an electrode n dined to be able to assess the surface area.  

Can I melt cobalt to make a plate or square electrode?  I thought I would make a mold out of fire brick and put cobalt chunks in it, cover it with a good layer of Black flux (Potassium salts of Boron & Fluorine) and heat it with an oxy-acetylene torch.  

I would sincerely appreciate any comments anyone cared to make aobut this situation.  Does anyone know a source for a cobalt electrode that is flat and square?  Does anyone have any comments on the casting process described above?

Thanks,
Tom

Here is a good source of metals.  We used them a lot.

Thanks,

I called them as well as Alpha Aesar, Spectrum, Thomas, Fisher and several smaller.

I wanted a thick, square piece to use as an eletrode. We are using chunks wired into a rectangle now. Foil will wear too rapidly and wire is the wrong shape.
