"Ornamental Blown Glass" (OBG)
Lynnwood, WA, USA
"Ornamental Blown Glass" or "OBG" is a hot glass blowing studio--located in Lynwood, WA, just outside of Seattle--that has had some very well-known artists on their staff over the years, mostly as they have been coming up and before going out on their own. Some of them are listed here:
Mariusz Rynkiewicz: Now famous glass blower, Mariusz Rynkiewicz, accepted a position of gaffer at Ornamental Blown Glass. He worked there from 1989 until 1995. During this period, Mariusz looked for ways to further develop his glass-blowing artistry. In 1992, he studied with Dante Marioni at the Pilchuck Glass School in Stanwood, Washington; and a year later, with Lino Tagliapietra at Pratt Fine Art Center in Seattle. Also in 1993, Mariusz became an instructor of glass blowing at the Pratt Fine Art Center. In 1995, Mariusz fulfilled his lifelong dream by becoming designer, gaffer, and owner of Studio Rynkiewicz in Everett, Washington.
Jack Pine, well-known for his glass pumpkins, worked for Ornamental Blown Glass in Seattle and Maytum Glass Studio in Boulder, Colorado. Jack originally worked in several mediums. When choosing glass as his favorite, Pine founded his own studio, Jack Pine Studio.
Surely there are others, but this is what I could find on-line without investing an inordinate amount of time.
