Alastair ross, back in the day, was the lead glass blower at Pairpoint Glass. He held the job a few decades ago, after the company moved to its current location on Cape Cod, Massachusetts. Alastair's son, Ian, would watch his father work with furnaces, molten glass and lead ladles to turn mounds of scorching-hot, shapeless material into things of beauty. Today, Ian (shown in the photograph at left) is the master glass blower at Pairpoint, which is now America's oldest glass company, in year 181 of operations. And among the things that Ian's hands regularly create are the handblown glass shades for Imtra's newly restyled St. Maarten Reading Lights, which yachtsmen can order with spherical- or martini-shaped shades.
