>Here are two 'metal-working' techniques I use with my 7th grade arts
>and crafts classes.
>1) Low Relief Sculpture: Students use a cardboard base and add
>layers of cut-out cardboard shapes; the more layers the better.
>When the armature is done, it's covered with white glue. Pieces of
>lightly crinkled foil are placed over the gluey armature and then
>patted into all the cracks and crevices. Large pieces will require
>multiple pieces of foil. After the surface dries, the foil along the
>edges is trimmed to one inch and then turned and glued onto the back.
>Students then blot black tempera paint onto the front surface, let it
>dry for 5 minutes and then buff it off with multiple paper towels.
>To hang the sculpture, we hot-glue a large paperclip to the back.
>This technique simulates embossed metal very well. We have used it
>for medieval shields in social studies as well as in art class
>2) Aluminum Flashing Metal Sculpture: Non-galvanized aluminum
>flashing is sold in hardware stores in 10 foot and 50 foot roles. It
>comes in a variety of widths, up to 20 inches. It can be cut with
>good scissors into a variety of shapes. It is the closest material
>to Mexican tin that I have found. We have cut out shapes and then
>done punched designs on them, using several magazines for backing,
>old sharpened screwdrivers and mallets. These pieces can be colored
>using permanent markers. We have also spray painted a base of enamel
>paint and then added details in acrylic paint. The aluminum can also
>be scribbed with lines, lightly pounded into concave shapes (old
>sandbags work great for this) and bent into three-dimensional forms.
>I find this material to have great possibilities and be quite
>reasonable in price. I actually incorporate aluminum flashing into
>my own mixed media sculpture!
>Hope these ideas will help you out.
