Visiting Macadonian designers & glass artists Janko and Mimi Gogusevski were visiting in the US, when they got the fever. For glass. And the only prescription is more glass.  Mimi and Janko are the owners of Skopje’s Studio Vitrum in Macedonia, and after a short visit to the Washington Glass School, decided to re-arrange their schedule to allow for a workshop in bas-relief kiln casting, headed by superstar instructor Audrey Wilson.

Mimi Gogusevski sets up the glass in the kiln.

Soon the phrase “Moeto letačko vozilo e polno so jaguli” was heard throughout the school. 

Working with Audrey, the couple explored options in creating architectural glass panels that they will be producing from their European glass studio.

We hope the artists are happy with their works and that we team up again sometime in the future – “Washington Glass School Goes to Europe”  is our dream!

Molds of sample patterns fill the kiln.

WGS Artist Cheryl P Derricotte @ HOME in CA.

Artist Cheryl Patrice Derricotte‘s new mixed media works are part of two venue exhibit “HOME” –  at California’s Orange County Center for Contemporary Art (OCCCA), and Vietnamese American Arts & Letters Association (VAALA) – open thru July 26, 2014. The exhibit delves into the deeper meanings of the word “HOME” – how it resonates on cultural, emotional, intellectual, religious, philosophical, political and spiritual levels—as a place, a space, a myth, a source of identity, a promised land, a state of being, a war zone, an impossibility, and/or an inalienable right.

One of the Washington Glass School’s studio artists, Cheryl had moved to California’s Bay Area a few years ago, and became integrated into the West Coast arts scene – and her sculptural work in glass and other media has been exhibited widely  Most recently, in addition to “HOME ,” at the OCCCA, her work was included in the 18th annual “The Art of Living Black” at the Richmond (CA) ArtCenter.  Her work has been a juried inclusion in the “Hyperbolic Crochet Coral Reef” at the Smithsonian Museum of Natural History (2010-2011); “24th Tallahassee Invitational (2009)” and “Terrestrial Forces (2004)”, both at the Florida State University Museum of Fine Arts; “Contemporary Glass (2005-2006)” at the San Francisco Airport Museum and Zenith Gallery Presents “Washington Glass (2007).” In 2005, Cheryl was the recipient of a D.C. Commission on the Arts & Humanities/National Endowment for the Arts “Artist Fellowship” grant.

Said Cheryl of her new works in the exhibit: “Identities shaped by home (or homelessness); natural beauty (or disasters), memories of happiness (or loss) inspire my artwork. Observations of current events, politics and urban landscapes are my entry into these issues and the resulting works on glass and paper.”

Cheryl is one of the few artists that has work in both venues – if you are out in Sunny CA – make a point to stop in! Congratulations Cheryl!

Washington Glass School Says Farewell to Nancy Donnelly

Artist Nancy Donnelly had many facets – sculptor, painter, bookkeeper, welder, printmaker; she is a Renaissance woman.

The Glass School says “So long, farewell, auf Wiedersehen, good-bye” to one of our own – glass artist Nancy Donnelly – as she leaves DC for an extended holiday in Europe and then moves to the “other” Washington.


Nancy Donnelly gives a “bench blow” for her roll-up glass as she assists Michael Showalter at DC Glass Works.

Nancy Donnelly “Green Eggs & Ham”, Fused and blown glass.

Nancy has been working from the studio since 2007. Originally a painter, Nancy embraced all aspects of glass  - blown, fused, cast; she sought out ever more directions in the medium. As she expanded her technical repertoire, she became a true mixed media sculptor. Her shows at galleries throughout the Washington, DC area began to be covered by the Washington Post art critic Mark Jenkins. In his review of Nancy’s recent “Transmission” show at Rockville, MD’s Common Ground Gallery, he said that her “striking sculptures” were “metaphors for creation and liberation, making them pertinent not just to one artist who has found her medium“.


Nancy Donnelly made the aprons for the cold shop – and everyone at the Glass School became Fashion-Forward models

Nancy also worked in the studio as the bookkeeper and organized many aspects of the school, including the course schedules and flyers. She kept the many studio resident artists in line and looked out for the welfare of all.

As Nancy transitions into the next version of uber-artist and world traveler, all of us at the Glass School will miss her terribly! Come back often to visit!

The Process: Public Art and Placemaking

DC Ward 7 Green Community Arch sculpture located at the new Unity Healthcare Building.

One of the Washington Glass Studio’s most ambitious public art projects has just completed installation. The DC Commission on the Arts & Humanities commissioned the sculpture for the new Unity Healthcare facility in Washington, DC, and the glass-and-steel artwork was installed without a problem this week.

Concept design for the Green Community Gateway Arch

The public artwork concept was designed and engineered to a high level.

The design of the public artwork was intended to mark the symbolic entrance to the Kenilworth / Parkside section of DC’s Ward 7. This area (near Caeser Chavez charter school, the Kenilworth Aquatic Gardens and the Anacostia Freeway) was recently identified as a DC Promise neighborhood – and its experiencing a renewed investment in neighborhood revitalization. After meeting with community representatives, the WGS team focused on themes that were strongly held. A “Community Gateway Arch” became the vision for the placemaking sculpture that would help identify the new environment. The glass panel insets in the 16′ tall sculpture would be made with the help of the neighborhood residents, students of the high school, and the staff of the new Unity Healthcare facility. The Washington Glass Studio worked with the DC Creates! Public Art Program selection committee, the DCCAH Council, Unity Parkside Health Care, the Ward 7 ANC and the community and held a series of glass “quilting-bees” and made a communal environment where community and art were not separate.

Artist Erwin Timmers oversaw the structural integration of support framework, LED lighting and glass panel insets.

The 16′ high x 14′ wide sculpture lit internally with LED lighting was one of the largest outdoor artworks installed to date for the Washington Glass Studio, and much went into the design, engineering and the fabrication of the steel framework.

In early 2014, with the structural foundation for the artwork finished and the steel framework underway, the call went out to the community to come make glass. By directly involving the public in the creation of the new landmark, the space would resonate because the artwork would have meaning to all – as everyone had the chance to tell their story.  The glass workshops were packed. Many of the people that came to work in glass returned to each of the scheduled dates – they loved working in glass and wanted to see how the artwork changed once fired. 

DC ANC Commissioner Willie H. Woods, Jr and DCCAH Exec Director Lionell Thomas were among the community enlisted to interact with the glass artwork.

By having many area residents making the glass art insets, the sculpture has an increased sense of local identity. The artwork arch stimulates curiosity, inspired some of the budding artists to consider new artistic avenues and on occasion, create a smile.


Many voices told many stories in the inset panels that made up the glass quilt archway.

“All New” Glass Fun Facts: Part 2

The WGS Blog returns to provide More.  Glass.  Trivia!

As far as the early history of glass making in Britain goes, the Romans brought the technology with them. This led to the European-wide spread of glass manufacture. British history records glass “Manufacture” dating back to the 13th century when “Broad Sheet” glass can be located to the areas around Sussex and Surrey. In the meantime the Venetians had thrived as glassmakers, as their glass became popular due to its brilliance and creative form. By 1330 the French had also developed “Crown Glass”. This took until the 17th century to be produced in England, in London.

 In England in 1676 George Ravenscroft invented “Lead crystal” by introducing lead oxide to the glass which took on a more brilliant appearance.

 The 17th century brought a new glass process from France, “Plate glass”, a term still used today. This was a process of pouring molten glass onto a table and then rolled. Once cold, the glass was ground under large grinding disks until optically smooth, making it perfect for mirrors. The French had legislated heavy duties on imported glass products which made it impossible for the Venetians to Export, and also offered generous incentives to any Venetian willing to work for them. By the 18th century this technology was being used in England at Ravenhead, producing the first English Polished Plate.


The Crystal Palace was a cast-iron and plate-glass building originally erected in Hyde Park, London, England, to house the Great Exhibition of 1851

1834, Robert Lucas Chance introduced “Improved Cylinder Sheet” glass which was produced using a process invented in Germany. This produced even finer and larger glasses. This was the glass used to glaze the “Crystal Palace” in London. Until a change in legislation in 1845 when the “Excise Act” was repealed, glass manufacture was under developed in Britain. Once the heavy tax burdens previously placed on glass manufacture were removed, production grew.

By the end of the 19th century glass bottles were being made by machine, increasing production threefold. The now “Chance Bros.” invented “Machine Rolled Patterned Glass”. By the start of the 20th century, “Owens Glass” in America had further developed bottle manufacture which increased output by 10-fold to some 2,500 bottles per hour.


By 1910 the first “Laminates” had been produced by Edouard Benedictus, a Frenchman, who named the process “TripleX.” 1914 saw the start of producing glass by the “Drawn” method. Invented by a Belgian man named Fourcault, glass was drawn vertically from a tank. A further development by Richeroux, another Belgian, was to pour the molted glass from a pot between 2 rollers to give a more even thickness and evenness for polishing.

In 1917 “Sheet Glass” was invented by Colburn in America and developed by “Libby-Owens”, a partnership of Michael Owens of Owens glass and his backer E. D. L. Libby. Further improvements were made by “Pittsburg Plate Glass” or PPG.

By 1923 came the first UK production of continuous polished plate glass using the single grinding system. Closely followed in 1938 by the twin grinding system. And then the float process was launched in the marketplace; invented by Pilkington Bros, and introduced in 1959. The significance of this process is that it produced glass with a brilliant finish and without the need to grind or polish the surface, making mass-produced glass with the qualities of polished glass. This was achieved by floating the molten glass on a bath of molten tin, creating a “glass ribbon”, even in width and thickness. This is still the process used today for the production of what is now termed “Float Glass”. 

Glass is commonly used for windows, bottles, modern hard drives and eyewear, and examples of glassy materials include soda-lime glass, borosilicate glass, acrylic glass, sugar glass, Muscovy-glass, and aluminium oxynitride.

Much of the functional architectural glass – like that used in shower doors, table tops, car windows, skylights, etc. – goes through a process called tempering.  Glass is pretty wonderful stuff, but it does have some bad habits.  First, it is brittle and has a tendency to crack when struck or heated unevenly.  Second, shards of glass are really sharp and pretty dangerous.  Tempered glass solves both of these problems simultaneously.  Glass is much stronger in compression than

Tempered Glass Process

If you can cause the surface of the glass to become compressed relative to the interior of it, you can harden it by a factor of up to 10.  There are a couple of ways to do this.  One is to heat the glass and then cool it very quickly.  The surface of the glass will cool much more rapidly than the interior.  The slow cooling of the interior causes it to want to contract more than the surface, placing the surface under considerable compression.   This strengthens the glass and makes it more scratch-resistant and heat-resistant in the bargain.  Another method is chemical tempering, in which sodium atoms on the surface of the glass are replaced with potassium atoms, which are significantly larger.  This also puts the surface in compression, and can be done with glass of complicated shapes that would not survive heat tempering.

One interesting effect of the tempering process is that tempered glass doesn’t just crack.  When tempered glass encounters a big enough stress, it shatters into small granules.  If the integrity of the surface of the glass becomes compromised, the interior, which is under huge tension, will disintegrate.  This is much safer than big dangerous shards, but does make the glass suddenly an awful lot harder to see through.  This is one reason why the windshield of your car is not made with tempered glass, but laminated glass.  Laminated glass is made by bonding two or more layers of glass with an ‘interlayer’ of plastic film which will hold the pieces together if the glass should crack.


Chicago’s Willis (aka Sears) Tower 103rd floor Skydeck had one of its famous glass ledges shatter an interlayer May 2014

Tempered glass is an extremely useful material, but it does demand some planning.  Because of tempered glass’ all-or-nothing breakage, it must have been already cut to the size, shape, and already have any holes cut out before the tempering process.  There’s no cutting the glass down to fit afterwards.

Tempering as an industrial process started in the 20th century, but it was a party trick far before that.  One of the first examples of tempered glass is something called Prince Rupert’s drops (or balls) , named after the Bavarian prince who brought it to the attention of the court.  If you let a blob of molten glass drip into a bucket of water, it will form an extended teardrop shape with interesting properties.  The bulbous end of the drop is tempered and can withstand extreme force, such as hitting it with a hammer.  The tail, however, is very delicate, and if broken, the whole thing will shatter into tiny pieces. 

When you think about it the stuff is a bit odd, but that’s glass for you.  It’s odd stuff.
