4-day workshop. Tuition $895.00 plus a $75.00 material fee due at class. All supplies and use of tools during class provided.
Previous knowledge of stained-glass technique is recommended. Prior drawing or painting experience is NOT necessary!

An innovator in the stained-glass world, Joseph Cavalieri’s work strives to take the art of stained glass out of the cathedral and bring it into everyday life. Joseph is a master of blending traditional stained-glass process with dynamic and imaginative imagery based in pop culture themes. This class is ideal for the artist who knows the basics of stained glass and wants to take it to a whole new level.
In class students will explore Aesop’s Fables as subject, selecting a story to base their work on. Then, with Joseph’s guidance they will create a glass panel approximately 12”x12” using the copper foil technique. Students will learn different processes to create imagery on the glass using kiln-fired paints, including painting, airbrushing, pen-and-ink style drawing, and sandblasting. Once the imagery is complete and fired, students will assemble the panels using the copper foil method of construction to create a finished piece.

In addition to the class curriculum, Joseph will be offering advice on marketing for artists and seeking out and applying for artist residencies.

Joseph Cavalieri’s glass art is at the intersection of mystical and post-cultural. His beautifully stained and painted pieces are at once an homage to traditionally religious stained-glass art and a cheeky discussion about the pop culture we know and love.

He is based in New York City, and has completed commissions, residencies, and staged exhibits all over the world. You can see more about him and his work at cavaglass.com

Susan Taylor Glasgow’s work pays extensive tribute to the era of Mother, Father, Lucy, Ozzie and Harriet in a language composed of images appropriated from the world of ‘50s and ‘60s TV and advertising.  She says she "sews, cooks and arranges" glass to reconcile the conflict over work and home, feminist ideals and the Madonna complex, duty and fulfillment.  The bustier forms of her Chandelier Dresses are a fantasy, which reminds us of the way things never were.

Glasgow grew up in Duluth, Minnesota. She graduated from the University of Iowa with a BFA in Design. Her sculptures are included in the collections of the Arkansas Arts Center, Little Rock, AR, the Alexander Tutsek Foundation, Münich, Germany, the Carnegie Museum of Art, Pittsburgh, PA, the Chrysler Museum of Art, Norfolk, VA and the Museum of American Glass, Millville, NJ.  Susan Taylor-Glasgow lives and works in Columbia, Missouri.

"Glass has gripped me from day one. In its many forms, glass is the one medium that has allowed me to create using combinations of art techniques I love from other media. Collage, drawing, sculpture, printmaking, painting, photography, and design... all come together with glass and heat as common ground.

“I'm a self-taught glass artist, specializing in fused glass sgraffito drawing and collage.

"I studied studio art for 4 years in the BFA program at Ohio Northern University, where I focused on ceramics, figure drawing, and watercolor before leaving school to start a family. My first experiences and adventures in glass began after college in 1995. I saved money from teaching art to groups of homeschooled students and purchased a tiny kiln, and the glass experimenting bonanza began in my garage.  My favorite way to work with glass is a method I call ‘glass powder sgraffito drawing’. You can read more about my work and the technique I use in this recent article: Making Art from Scratch”

Master Class in Painterly Glass with Kari Minnick

Thursday, October 24- Monday, October 28

5-day workshop. Tuition $1,095.00.
A deposit of $545.00 is required to reserve your spot; tuition balance of $550.00 due August 1.

Prior glass experience is beneficial but not required.

Kari ups her game again with her newest workshop “Painterly Glass”. In this creative workshop students learn methods of creating a two-dimensional glass composition or panel using glass materials to achieve a painterly or painting-like quality. But…NO PAINT OR ENAMEL WILL BE USED! 

We will use Bullseye glass, powder, frit and stringer to simulate paint and highlight the unique qualities that working with glass brings to the process. Gritty, slick, or robust relief, kilnforming materials and processes give us a vast range of painterly styles from creamy impasto to ephemeral watercolor washes. Students will learn painterly effects by utilizing unusual wet and dry powder processes, multiple firings and careful temperature control. 

Painterly glass is more than the techniques used to achieve it. It is a mindset; a consideration of “the big picture”; layer by glass layer. Students will explore technique that supports strong composition, rich surfaces, and depth. Color, composition, and the effective use of opacity and transparency will be considered. Students will develop ideas through preliminary sketches, paper cut outs and/or test pieces leading to the completion of two larger glass projects.  

Topics to be covered include: color mixing, considering both sides of the glass, layering strategies, light transmission as well as 2D to 3D by slumping, draping or function. 

Prior glass experience is beneficial but not required. This highly creative and hands-on course is of interest to kiln glass workers as well as artists of other media.
