The Tank Test Run of January 31st, 2012, was one of a number of 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.
