AO Glass is one of the most innovative and sophisticated hot glass studios in the country. From our home in a converted manufacturing plant in Burlington, Vermont, we design and produce high-quality glass products, from lighting fixtures to barware to tabletop. We integrate traditional Scandinavian techniques with American technological innovation and a New England work ethic to create the high-end glass that the country’s top lighting firms demand. Locally owned and operated, AO prides itself on its team of glass artists and its positive workplace environment.


AO offers both free-blown and mold-blown designs, casting and pressing. We’re problem solvers who work with our manufacturing clients through the entire development and production process.




AO begins with Rich Arentzen and Tove Ohlander

Founders and AO owners Rich Arentzen, an American, and Tove Ohlander, a Swede, met at Sweden’s National School of Glass in 1994. They founded a glass blowing studio, and began their family, in Baerum's Verk, Norway. Drawn to a more flexible lifestyle, and to Burlington in particular, they moved to Vermont in 2007 and started AO Glass, named for the first initials of their two last names.

From Snowmen to Lights

To combat the recession that hit just as they lit their new furnaces in their Burlington studio, they began making glass snowmen. Vermont Senator Bernie Sanders brought the snowmen to the Smithsonian Museum as part of his “Made in America!” initiative, and AO’s first successful product line was launched. In 2014, AO developed partnerships in the glass lighting industry, and Hubbardton Forge and Lindsey Adelman became their first big design clients.

The AO Transformation

This transformed AO Glass from a small art glass studio to a premiere vendor of glass components in the lighting industry. Their unique set-up, size, and industry knowledge enables AO to provide clients with unique sample sessions and large manufacturing capacity. This, coupled with an unmatched attentiveness to design and quality, problem solving, and guidance throughout the entire process, makes AO Glass a great company to work with
