Henry Halem talks about all glass artists except Mark Peiser buying their color from manufacturers. Oral history interview with Henry Halem by Catherine Whalen and Barb Elam, conducted via telephone, June 3, 2018, Bard Graduate Center. Clip length: 00:32.

Henry Halem: It’s all the same. Color is certainly all the same, cause everyone buys their color from the same companies that manufacture color. So it’s not like painting where you have different color styles for painters from the West Coast than you do for the East Coast. But in glass, it’s all the same color. Because color comes from these couple of three companies that manufacture color bars. No one melts their own colors. The only one that melts his own colors is Mark Peiser.
