In this project, I made a 4x4" tile on green/black iridized glass. I believe it was
Spectrum irid 96 -- but honestly can't recall.. I fashioned a seahorse out of dichroic chips and glued them to the iridized side of glass.
Then the tile was placed faced down on some pre-fired 1/32" fiber paper and fired.
The result was beautiful. Because the irid glass reflects light, the picture doesn't do it justice.
