AO Glass is one of the most innovative and sophisticated hot glass studios in the country. From our workshop in a converted manufacturing plant on Pine Street in Burlington, VT, we design and produce high-quality glass products: from lighting fixtures, to bar-ware, to home goods. AO Glass is locally owned and operated, and we are proud of our team and our positive workplace environment.


At AO Glass we offer designs in both free-blown and mold-blown techniques, as well as casting and pressing designs (visit our media gallery for examples of these techniques.) We’re problem solvers, and work with our manufacturing clients throughout the entire development and production process. Drop us a line if you’re interested in a quote.




AO begins with Rich Arentzen and Tove Ohlander.

Founders and AO owners Rich Arentzen, an American, and Tove Ohlander, a Swede, met at the Orrefors (Sweden’s National) School of Glass in 1994.  They founded a glass blowing studio, and began their family, in Baerum's Verk, Norway in 1998. Drawn to a more flexible lifestyle, and to Burlington in particular, they moved to Vermont in 2007 and started AO Glass, Arentzen-Ohlander Glass.

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.  Our VT Senator Bernie Sanders assisted in getting the snowmen in to the Smithsonian Museum as part of his “Made in America!” initiative. 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.

The lighting industry partnerships transformed AO Glass. From long persistence of existing as a small art glass studio, the business changed into a premiere vendor of glass components in the lighting industry.  Their unique set-up, size, and industry knowledge enabled 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.
