003710 Ten (10) 2012 JABO Dave's Tank Test RUN "HANDPICKED KEEPERS" MINT 9.0 3/4" +/- Marbles
Some great pupils and Aventurines. A fair representation of the runs families.

The Tank Test Run of 2012 was one of the small, experimental productions carried out by Dave McCullough at JABO during the final phase of contract runs. It is sometimes referred to simply as Dave’s Tank Test because it was not a formal collector‑financed run like Foxfire or Indian Summer, but rather a technical experiment to test the furnace tank, cullet blends, and production capacity before later contract batches.
