Hi Matthew, Pardon my ignorance, but I do not quite understand what you mean by "wrapping it in a flat spiral that lays on the bottom of the reaction vessel". To me it sounds like wrapping the silver spiral so that it is not exposed to DW, totally defeating the original purpose. Would you be so kind as to spell it out with a few more words? The idea of spiralling for greater surface area I find remarkably innovative. Making the initial spiral by winding the wire on a coneof some kind, removing the spiralling silver wire cone-shape and then pressing down on it with a flat object in order to get the "flat spiral."

Enough wire should be left unwrapped to rise vertically to the lip of the vessel. This lead should be protected from premature dissolution by running through a sleeve of Tygon tubing or other inert tubing. The flat spiral of silver wire will provide more surface area than a comparable mass of flat metal. Oxide by-products can be cleaned off with a stiff-bristled tooth brush. This type of wide anode might best be combined with thermal stirring. Best regards, Matthew
