The experiments I've done may be a variation on this theme. I've
fired colored glass shards and even marbles in and on pieces.
Only the largest marbles needed to be broken first - I was firing to
cone 10. I left smaller ones intact. The shards were only small
enough to fit the space I was filling. Because the melted glass only
covers concave parts of a piece, and I didn't happen to want glazed
and unglazed surfaces juxtaposed, I glazed the pieces first. Then I
placed marbles inside or, in one case, on a broad, flat rim with a
just-in-case raised lip and fired.
The results of using found glass and marbles were fun and sometimes
surprising (you have to be open to serendipitous endings to enjoy
this). Our technical members can surely explain this better than I,
but basically you need to remember that glaze making is about
chemistry rather than pigments; when you fire colored glass, you will
likely not get the color you were looking at beforehand. The cats-eye
marbles were especially fun, yielding pinwheel-like designs.
Yours in clay,
Jaine

hi glad to read yourpost, just recently read about folk potters who put
glass on rims of pieces and they fired with an almost lava flow like lok
on vertical planes. i was going to post asking if placing glass on pieces
was an ok thing to do and read yourpost- thanks.
