In 1970, the first buildings at WheatonArts opened to the public. The present administration building housed the museum collection. There was also a gatehouse, a General Store, a museum store called the “Brownstone Emporium,” and support facilities for carpentry and painting.
Soon construction began on the Museum of American Glass and the T. C. Wheaton Glass Factory. Until completion of the factory, glassblowing demonstrations were conducted in a glass furnace placed in a small structure adjacent to the entrance. The museum opened in 1973, followed shortly thereafter by the opening of the T. C. Wheaton Glass Factory, Dr. T. C. Wheaton Pharmacy, West Jersey Crafts, Arthur Gorham Paperweight Shop, Crafts and Trades Row and a barn.
