Oregon Public Broadcasting has some treats in store for viewers Thursday. On Oregon Art Beat, at 8 p.m., one of the glass artists featured is Nehalem glass-blower Roger Crosta, pictured right.

Apparently, Crosta quit his job as a building designer and contractor when he discovered glass blowing, and he is now one of the two people in the country working in an ancient process of glass blowing called scavo.

Scavo means "dug up" in Italian, and consists of a formula and process used to give glass vessels the appearance of being excavated from ancient ruins.

You can see his intriguing lighting fixtures and chandeliers at his Web site, (www.ikbana-blown-glass.com/index.htm)

Video clips of the story can be viewed online immediately following the broadcast at (www.opb.org/programs/artbeat)

At 8:30 p.m. Thursday, OPB will present Oregon Field Guide, about new tools that allow Oregon State University scientists to track the complexities of ocean circulation. OSU scientists are using robot submarines, navigational satellites and computers to explore the movements of currents in the depths of Yaquina Bay off Newport.
