“WGS Is Home” — A Conversation with Jeff Zimmer

Washington Glass School at 25

Jeff Zimmer was one of the earliest resident artists at Washington Glass School, working out of the original Half Street SE studio in the early 2000s. Since then, his career has taken him internationally — from earning his MDes s at Edinburgh College of Art to exhibiting in the British Glass Biennale and having work acquired by museums including the Victoria & Albert Museum in London.

For Washington Glass School’s 25th Anniversary, Jeff reflects on finding his voice, building community, and why WGS still feels like home.


On his first memories of WGS

“My first memory of WGS is helping carry rolls of old carpeting down endless corridors to clear the original Meltdown studio site.

I had only been working with glass for a few years, and Tim brought me on to assist classes — even though sometimes I was learning something only minutes before the students!”

Later, as one of WGS’s first resident artists, Jeff spent countless nights cycling to the Half Street studio after work, often staying until midnight.

“The first works I really consider to have my own voice came out of that time.”

Jeff Zimmer, “Untitled Political Landscape“, 17 layers of enameled & sandblasted glass, lightbox, 2008

“WGS felt like it didn’t participate in hierarchy. I felt supported to pursue my own path.”


On finding his artistic voice

“At the time, I perceived the glass world as very hierarchical — dominated by glassblowing, with painting on glass seen as secondary or decorative.

Now, I love glassblowers and beauty, but that’s not my voice.”

What Jeff found at WGS was freedom to explore ideas outside those expectations.

Jeff Zimmer, “The Wake of The Hero“, layers of enameled glass, assembled in lightbox, collage, 2011

“There was already a concern with complexity and ambivalence in the work I was making then. That has stayed with me ever since.”


On thinking through glass

“As the years progress, I realize I think more and more through the material itself — not only its techniques, but its associations.”

For Jeff, glass carries centuries of layered meaning.

“I can draw on medieval associations of light and virtue reflected in stained glass, ideas of transparency and opacity, glass as both window and barrier, fragility and strength — even the ‘black mirror’ of our screens.”


“Ideas don’t really exist for me until I can find a way for them to exist in glass.”


On teaching and exchange

Jeff has taught internationally at Pilchuck, Bild-Werk Frauenau, Berlin Glas, and other institutions, while co-running Glass Lab Edinburgh in Scotland.

“Different glass communities shape artists in very different ways,” he says.

He notes how Germany’s technical school traditions, the UK’s emphasis on casting and painting, and resourceful studio cultures in South Africa and Latin America all create different relationships to the material.

“When those communities meet internationally, there’s a real exchange. That’s where things become interesting.”


On teaching beyond technique

“Technique matters, but it’s not the point.

I want students to use technique to find their own voice. The best moment is when you see someone take a process and immediately run somewhere unexpected with it.”

Teaching, he says, has also sharpened his own practice.

“It forces me to break instinct down into conscious steps.”

Jeff Zimmer chats about artist Audrey Wilson’s concept.

“The barriers to working in glass are high. Having a place that supports experimentation early on can completely change what becomes possible for someone.”


On success, recognition, and reality

Despite international awards and museum acquisitions, Jeff speaks candidly about the realities of sustaining an artistic practice.

“Some of the times I’ve had the most apparent ‘success’ were also the times I was supporting myself as a 45-year-old cycle courier.”

Recognition can help open doors, he says, but often quietly.

“The V&A acquired a piece of mine, and it sat in storage for nearly a decade before going on display. For most of that time, its biggest visibility was on my CV.”

On returning to Washington Glass School

“How does WGS fit into my journey? It came into my life at exactly the right moment.”

Jeff Zimmer and WGS Founder Tim Tate.

More than two decades after leaving DC, Jeff says returning to WGS still feels deeply personal.

“WGS is home.

Whenever I walk through the door, I feel embraced like family. There’s warmth, curiosity, generosity — that hasn’t changed…I’m proud of what you’ve built. And I’m grateful it’s still a place I can come home to.”


As part of the Washington Glass School’s 25th Anniversary programming, Jeff Zimmer returns this summer to teach a special intensive workshop:
5701 – Obscuring and Revealing
July 13–17
This five-day masterclass explores layering, transparency, dimensionality, and painted imagery in glass. Students will create personal three-dimensional layered compositions using glass painting techniques, collage, and spatial construction to investigate how glass can simultaneously conceal and reveal.

Washington Glass School at 25: Artist Spotlight on Trish Kent

Some artists arrive with a five-year plan. Others arrive because they simply fall in love with the material.

For Trish Kent, it started with wonder.

studio artist Patricia (Trish) Kent talks about her work at Montpelier Arts center 2024.
Trish Kent talks about her politically charged work at Montpelier Arts Center, June 2025.

“I have always loved glass,” she says, recalling a delicate glass ballerina she treasured as a child and her mother’s collection of figurines and wine glasses. Years later, after seeing a friend create functional glass plates, she was hooked. She learned the basics, then found her way to Washington Glass School, looking for a place where she could work freely and explore the medium on her own terms.

Her first interaction with still makes her laugh.

“The moment I walked into WGS, Tim Tate asked me if I was doing my art to make a living. It was such a laughable question.”

The answer was no. Art wasn’t about building a business. It was about having the time and space to create.

That freedom — paired with immediate access to experienced artists willing to help — became central to her experience at the school.

“What I loved and still love is the availability of Michael, Tim, and Erwin to show interest and help with any questions I might have. To be able to walk into the office with a problem and get an answer then and there is a dream. That is so rare.”

Now, after 13 years at WGS, Trish describes her studio days as fluid and social — working steadily, pausing to talk with fellow artists, then diving back into the process again. The rhythm of making art is intertwined with the rhythm of community.

One of the things she values most about the shared studio environment is the openness between artists.

“You can watch other artists do their work and copy their process if you want to. I don’t necessarily have to take a course to try a new technique.”

She laughs remembering one of Tim Tate’s favorite sayings:

“All artists copy other artists.”

Like many glass artists, Trish learned quickly that the material demands patience — and sometimes a box of bandages.

“Glass work taught me that I will get cut as a new artist often! I will have to wear numerous Band-Aids at the same time if necessary!”

Thankfully, those cuts have become far less frequent over the years.

But the harder lessons came through persistence. One especially meaningful project — casting the hands of her daughter and granddaughter — failed repeatedly before succeeding.

“It took four times to get it right,” she recalls. “What I loved is that the other artists in the studio offered suggestions to fix my problems, which finally worked.”

That collaborative spirit is one of the defining qualities of Washington Glass School. Trish describes the school as a place where artists celebrate one another’s successes, support each other through disappointments, and genuinely want to help.

“We have become a close-knit community but still welcome new artists in. We celebrate birthdays, anniversaries, awards, and sales. We also commiserate when people fail or don’t receive the sale or award they had hoped to get.”

Over the years, her own artwork has evolved alongside that community. She remembers another pivotal challenge from Tim Tate:

“Your dresses are nice, but what’s next?”

“It pushed me to move on and try something new,” she says. “He was right.”

Her work has often reflected personal fascinations and emotional responses: elegant dresses because she loved dresses; playful pigs inspired by a flying pig sign in Seattle; distorted American flags expressing anger and frustration with the country’s political climate.

And while the future direction of her work remains uncertain, she approaches it with honesty and curiosity.

“My future art is unknown, which is slightly more scary than exciting to me. I’m open to suggestions!”

As Washington Glass School celebrates its 25th anniversary, Trish reflects on the resilience of the studio and what it represents to its artists.

“I know they have been through good times and not-so-good times and how they keep going. It shows the rest of us that you shouldn’t get totally down just because there are tough times. It gives the rest of us hope.”

When asked what she hopes the school will be like 25 years from now, her answer is simple:

“Exactly the same as it is now — just better funded!”

At 79, Trish says people are often surprised that she works in glass.

“No one they know does art at my age — and if they do, it’s painting, not glass art.”

But perhaps that spirit of curiosity, experimentation, and reinvention is exactly what defines both Trish and the Washington Glass School itself.

And maybe no description captures the atmosphere of the studio better than this:

“Hearing a champagne cork pop to celebrate someone’s event is the best sound ever to hear at WGS.”

For Trish, the friendships formed at the school may be the most meaningful part of all.

“The interest, support, friendship, and care given to me by Michael, Erwin, and Tim have added so much to my life. I realize now that my life is so much better because you three are my friends and have taught me so much with kindness, consideration, and even joy.”

2025 GATEWAY OPEN STUDIOS TOUR Saturday, May 10, 2025 from 12 – 5 pm

The Gateway Arts District is the largest in the region, but it is easy to underestimate as many of its artists work in spaces tucked away or without public hours. An exciting element of this event is that visitors can see spaces not always open, view artists’ work and workspaces, and talk to the artists about their practice on this special day of open houses.

The district roughly encompasses a two mile stretch from Mt. Rainier to Hyattsville with most locations on or around Route 1/Rhode Island Avenue. Best to start at the Washington Glass School at 3700 Otis Street.  While some intrepid art goers choose to walk, Free shuttles will be operated along the corridor to help people cover more ground. Street parking is available as well at Lots 1, 3, and 4 in Hyattsville. Shuttle routes and a parking map will be available on the OST website.

In addition to visual art, many neighboring businesses will be poised to welcome visitors for food, drink, and further discovery of the many small and creative places within the Gateway Arts District.

After the open studio tour, all are welcome to the outdoor afterparty from 5 pm – 7 pm hosted by Broken Square and featuring music, skateboarding, and a food truck at 3698 Wells Ave, Mount Rainier, MD. If something quieter is your preference, head to Portico Gallery at 3807 Rhode Island Ave, Brentwood, MD 20722 for an end of the day porch hang.

Thank you to our sponsors Prince George’s Arts and Humanities Council, MiXT Food Hall, and Gateway CDC.

The event is FREE and open to the public. Visit https://www.gatewaycdc.org/ost2025 for a map of participating artists and studios to plan your self-guided tour.

Washington Glass School: A Legacy of Art, Resilience, and Community

Washington Glass School ca 2004, located in the Washington Sculpture Center in SE DC.

In the aftermath of the 2000 Artomatic show, renowned glass artist Tim Tate and metal/eco-artist Erwin Timmers felt the need to create a space for the growing glass art community in Washington, DC. Their solution was the founding of what was first called “Meltdown”—the future Washington Glass School. The school’s very first class, held on September 13, 2001, came in the shadow of one of the most tragic days in American history. While the founders initially considered canceling the session, the overwhelming desire of the students to move forward created an indelible bond. The class became a healing space, where sadness and fear were channeled into creativity and connection.

From those early days, the Washington Glass School (WGS) has embraced community and resilience as core values. In 2003, the school relocated from its original home—now the Rubell Museum in DC’s Southwest neighborhood—to the Washington Sculpture Center. Michael Janis, an innovative artist who joined the school that year, became a director by 2005. His leadership, alongside Tate and Timmers, continued to steer the school as it grew in reputation.

In 2006, a turning point came when the school’s building was taken by eminent domain to make way for the Washington Nationals’ baseball stadium. Unfazed, the WGS team moved just outside the District to Mount Rainier, Maryland. It’s been their home ever since, where they continue to teach, collaborate, and create public art.

WGS Directors (L-R Michael Janis, Tim Tate, Erwin Timmers)

WGS has evolved into a dynamic hub for artistic exploration, encouraging artists to challenge the conventional limits of glass as an art medium. Their collaborative spirit thrives, with glass artists working alongside creatives from other disciplines, producing public art that speaks to the heart of the community.
