Copper Work : An Illustrated Text Book for Teachers and Students in the Manual Arts PDF

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.

During the past few years many experiments have been tried in the development of Manual Training Courses and much time has been spent in discussing of what lines of work they should consist.

Wood and iron were the first materials used and are yet indispensable, but experience has led those who are developing this work to believe that there are other materials as well adapted to Manual Train ing work in all its various forms.

Clay, used not only for modeling but for ceramic work as well, leather, brass, and copper are materials that have also been put to the test and found satisfactory in many ways.

In ancient times copper was known as a useful metal, and down through the ages it not only held its own but increased in usefulness.

Among its valuable properties may be mentioned toughness and ductility; its toughness enables it to be beaten into thin strong sheets, while its ductility enables it to be drawn out into fine wire.

Copper readily forms important alloys, such as brass from copper and zinc.

Work in sheet copper and brass has been introduced into the public school course with gratifying results.

It has proved itself to be a valuable departure from other branches of Manual Training work and gives promise of being per manent.

Sheet copper and brass offer possibilities for various kinds of treatment, either in the flat work which includes saw piercing, embossing and enameling, or in the raised work.

There is something about this work that appeals to pupils and holds their interest.

The nature of the material,hard enough to offer some resistance and yet pliable enough to allow its being wrought into many forms, the durability of the object when completed, and the variety of colors that may be obtained, especially with copper, all tend to make the subject not only interesting but fascinating.

All exercises in sheet metal should be of some real value to the pupil; no time should be spent on work done simply for practice, but the various steps should be learned in th
