New blue glass casting

Over the weekend I kiln casted a 17kg slab of blue glass roughly 10” x 46” x 1.5” thick. The glass casting uses Spruce Pine PWV clear cullet and billet we made at the University of Texas Glassblowing shop. The Blue is gaffer blowing color that is the dregs from the crucible after their color making. put about 3 kilos of opaque blue in it along with some aventurine blue glass frit.
