After graduating from Massachusetts Institute of Technology in Cambridge with a PhD in ceramics, Howard Sawhill worked thirty years with DuPont Electronics leading research and development teams that introduced new ceramic-based products into the marketplace. In his second career, he started Cone Blue Pottery, where the mainstay is research and development of ceramic glazes. He is currently working in collaboration with potters on challenging glaze issues and performing glaze studies aimed at improving the understanding of glaze performance. Examples of glaze research and development studies, collaborations, videos and his contact information can be found on his website.
