Ceramics: Using marbles and enamel

I wanted to use other materials with my ceramics, so I used some of my marbles to put into circles and squares of clay, so that when they were fired the marbles would melt. As the glass cools at a different rate to clay, some of the marbles had cracked inside, which I think makes a very decorative effect. I also used some of the objects I have collected to make imprints in the clay. I then used enamel to add colour to some of the imprints. I added these clay pieces to the metal and recycled squares and circles I had made, to make a small collection of each.
