I have shown in the drawings a four-sided box, two of the opposite sides being glass; but it will be obvious that the structure so far as the glass is concerned may be considerably varied Without departing from the spirit of my invention. For instance, since the object of the perforated metal sides is simply to allow the solution to act upon the copper it will be clear that the box might be made entirely of glass, and in this case the box would be submerged an inch or twobelow the level of the solution, so that the lat ter would act upon the copper from the top, the result of this being that the reddish appearance would begin at the top and gradually extend toward the bottom of the box. Therefore I do not wish to be limited to the exact construction of this box shown; but
