Modeling Glass: Feathers and More with Lois Manno

Three-day workshop. Tuition $725.00

We will collect a reserve fee of $100 to secure your spot.  The reserve will become part of a $365.00 deposit due January 15, 2018. The balance of $360.00 will be due March 1, 2018.

Traditional techniques of working with frit and powdered glass to create three-dimensional objects tend to be labor-intensive, as in the extensive amount of mold-making and painstaking packing required of pâte-de-vérre. Over the past five years, Lois Manno has focused her creative energy toward developing a different way to work with powders, one that opens an entire new world of creativity.

Lois has developed a medium system that turns messy powder into a manageable material with the consistency of clay. The resulting Modeling Glass™ has a smooth, firm texture, stores almost indefinitely, and is not sticky. No freezing is required, nor are molds involved. The material can be thinned with water into a paste, or can be formed into a shape and dried before firing. This dry state is where much of the cleanup can be done, almost eliminating the need for coldworking.  Modeling Glass can hold a great deal of detail at lower temperatures, and can also be used to create interesting effects at higher fuse temperatures. It’s possible to do things quickly and easily that would normally take many hours of studio time.

Lois will teach her method of mixing Modeling Glass and students will learn step-by-step how to use the material to make their own realistic glass feathers. Her feathers have received a great deal of attention in the glass community, and this is the first year she will be sharing this new way of working with glass. Students will also be introduced to other ways of working with Modeling Glass as it has nearly limitless possibilities. After five years of experimentation, Lois has just scratched the surface of what this material is capable of!

Display methods will be discussed and demonstrated. Firing schedules will also be provided.


Friday- Sunday, June 22- 24, 2018
Tuesday- Thursday, June 26-28, 2018



Lois Manno is a lifelong fine artist and award-winning writer, but fused glass has become her favorite medium. Her work is in several galleries across the country, and she is represented in many collections, including the Department of the Interior. She has been a guest blogger for Bullseye Glass and has devoted herself to perfecting Modeling Glass over the past several years. Lois is excited to share this new product with the glass community and can’t wait to see what creative doors it will open.
