To their credit, Buccini/Pollin never complained about the preservation requirement. Working with J&M Preservation Studio, they used laser technology to record the exact dimensions and shape of the original tiles, so they could be replicated. Fortunately, Boston Valley still had the formula for the orange glaze. The results at ground level are so good, they may be better than the original. As a bonus, the company also set aside the corner of Elfreth’s Alley for a new park designed by Land Collective, as part of a public effort overseen by the non-profit Community Design Collaborative.
