Much depends upon the last finish of the surface of the plate, and as a fine impression is desired in the same ratio, the operator must exercise care and skill in this operation.

Some buff the smaller plates on the hands, by resting them on the fingers in such a manner that the buff cannot touch them; some by holding the edges with thumb and little finger, with the remaining fingers under, or on the back; and others buff on the holder.

When this last method is adopted, it requires the greatest caution to prevent the dust from getting on the buff.

The holder should be wiped clean.
The plate frequently slips off or around, and the buff comes in contact with the bed of the holder.

When, however, the operator is so unfortunate as to meet with this mishap, the utmost care must be observed in thoroughly cleaning the buff cover before further buffing.
In this last buffing it may be continued as before, except without the application of polish powder to the last buff.
