The presence of highly electrically conducting powder in substantial quantities at the bottom of a good cell must have shorted the electrodes, thus disrupting the electrolytic process. The passage of high current through a narrow cross...

The laked areas have to be removed by polishing before the castings can be plated. This adds considerably to the overall cost...
