We have been experimenting with fusing and slumping glass. How many on the
list are working with glass in this way?

This year my 4th graders formed ceramic dishes using a slab of clay and
plaster drape molds that they each made by pouring plaster into a stryofoam bowl.
 When they glazed them, I let them choose glass marbles to put in the bottom
of the dish. WOW! What fun discoveries they made! The mables melted and
were an absolutely magnificent addition to their finished bowl. They used
gloss glazes all over their bowls first, then placed the marbles inside. The
red marbles turned bright yellow-orange and the clear with colors swirled
interestingly. The process of ceramics is always a surprise in the finished
product and this was the ultimate fun for them! When I ran out of the round
marbles I went to a big crafts store in my area that had big bags of glass
"stones" (used in flower arrangements) that have flat bottoms and we used those with
ecellent results, as well. On sale they were a very good price for 5lbs.
If you decide to try this, I suggest that you wash each dish before the kids
handle them because their is a "glass dust" left from the firing that have
little sharp pieces. I fired the pieces at cone 06.
