MATERIALS.

Copper is the material best suited for the work outlined in this book, although the processes as described may be applied to brass or silver. Brass may be used successfully in the flat work, but for raised work copper is the best material for the beginner.

Copper is obtainable in different thicknesses and in various grades but the best grade should be used. For most of the work from 18 to 24 gauge is used, while metal from 12 to 18 gauge is used occasionally.

Copper wire is used in several sizes for making rivets.
