The new process is vastly superior AND the old process was woefully insufficient. The new process involves me buffing with red rouge on a stitched wheel then with blue compound on an unstitched wheel, and then hand polishing on a velvet board with black ferric oxide powder. It seems that the shinier the plate is, the faster it is overall. I should also remind that mine are Becquerel-process dags and are far slower than bromoiodide sensitized daguerreotypes that are developed over mercury.
