Re: [teacherartexchange] clay and plaster question

Hi,

A number of years ago, I did this-it was plaster casting.

This is how I did it:
I piled the clay into a drawer from an old bureau and leveled it off.

I kept it moist with plastic and wet towels - it could be reused.

I had the kids build rectanglular frames from cheap strapping they
butted and glued and nailed with brads at the corners. They hammered
a row of nails on the inside several inches long (sticking out) and
put screw eyes 2/3 way up.

I used pieces of burlap maybe 3" square but not measured.

When ready the kids pushed the frame into the clay. In the aperture
they pushed items-plastic toys rocks twigs, textured items,
whatever.....

The items were removed leaving an impression in the clay. Then the
paster was poured into the frame and burlap peices put on top to give
the casting more strength. (Of course the nails sticking in the sides
also give armature support.)

Let the plaster set and then with some good strength, yank the casting
out. It will be in its own frame and you can add wire to hang it.

The plaster can later be painted if you want.

It was a cool project-I did it with a high school group in the 80's.

But now I teach K-8.

Good luck,
Barbara from Boston
