Another Buddha!!!!  On this large Buddha what I did was to prefuse a sheet of Bullseye Irid and a sheet of clear with the irid on top facing up. I used a schedule with a good bubble squeeze.  I fired it to around 1440.  Next I placed that glass on the mold that was sprayed with MR97 with the iridized glass facing down against the mold.  so easy and so gorgeous!! can do this in one firing....I am just nuts about not wanting a single bubble!!  If you do it that way be sure to use a slow bubble squeeze program!
