Metal Coloring and Finishing

Annotation

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. The subject of metal finishing and coloring has received but scant attention in mechanical publications; this is rather surprising when we note the inclination of the manufacturers of today to combine this artistic treatment with utility, and add contrast of color to the severe straight-line plainness of our commercial products, to produce more beautiful effects. There is nothing new in metal coloring. Ages ago it was old in Japan, and to the Orient we must really turn for original authority on successful coloring of metals.
