Zinc Suitable for Electrodes Utility

 Amazon has a Chinese vendor selling small zin flower pots. Approx. 5" height.  They are coated with a plastic to protect the surface.  Very inexpensive.

I cut a section of one ( about 0.75mm thick) for use as an electrode in Cu/Zi.  and Ni/Zi cells.

I easily removed the organic coating with ethyl acetate and rubbed the surface with a piece of foamed copper.  A dip in 5& aq. HCl solution can clean the surface before use.

This zinc sample was also givne a 6 ton press to flatten the surface.
