A practical treatise on the technics and principles of dental orthopedia and prosthetic correction of cleft palate . ghly rinsed in hot water; this is to remove the borax andloosen the oxide preparatory to polishing and plating them. In finishing the bands,hold them on a wood mandrel somewhat the form and taper of the respectiveteeth. All sharp and projecting portions that are likely to irritate the mucous CHAPTER XIX. TECHNICS OF REGULATING BANDS 163 membrane should be removed with a file, or with a fine emery wheel, and the sur-faces rounded, smoothed, and polished with tripoli on a felt wheel and a coarsehair brush wheel; then a fine brass wire brush wheel is used for the final polishingand burnishing. If care has been observed to prevent oil or grease of any kindfrom coming in contact with the parts, from the hands, or otherwise, while polish-ing, they can be carried immediately into the plating solution. When the appliances are of platinum and gold alloy, if highly polished andkept in that condition, they present a far more artistic and inconspicuous ap-pearance without gold-plating. The Plating Outfit for regulating appliances employed by the author is shownin Fig. 104. It takes its current directly from the Edison 110-volt direct currentthrough the medium of a series current tap supporting a 16-candie-power this seems to produce a current of too high voltage, it may be reduced one-halfby inserting an 8-candle-power lamp. Where the direct current is not at hand,a single one-gallon cell (Daniel, Smee, Bunsen, or preferably, an Edison Lelande)can be substituted. The gold-plating solution advised by the author is made by dissolving 30grains of Mallinckrodts Gold Chloride in about one quart of hot distilled water;then add chemically pure cyanide of potassium until the solution is clear; it canbe used cold or slightly warmed. This solution contains far less cyanide than theusual solution recommended, and will be found to preserve the anode much
