What is design? It's a way of thinking and a way of making. Over time, artists and craftspeople have developed a "language" that helps them not only to describe their projects, but to plan them as well. These elements and principles are guidelines that help artists make good choices when creating artwork. Using paper, drawing implements, scissors and glue, students will learn the basics of design that can then be applied to their glass making in the future. This fun two-day workshop will help build your skills in making more professional work as well as discover more about your own creative process.

Are you interested in incorporating metals into your kiln glass work? This is the class for you! In this two-day workshop you'll make a variety of jewelry pieces that incorporate copper, silver and gold in a variety of forms. You'll be introduced to tools and techniques that will help you change the look of the metals before placing them in your composition, and several ways to successfully lay up your pieces. We'll go over all of the firing schedules in detail, too. And, we've incorporated a NEW project into the class curriculum using Bullseye's new Alchemy glasses, which does amazing things with silver. This is your chance to try it for yourself!

This four-day class explores the related textures in fabrics, baskets, and weavings which are the foundations and the sources of inspiration for Erna’s creative and technical approach to glass design. 

Working with frit, glass powders, reactive glasses and metallic elements, students will use these materials to create components that result in unusual color shadings and visual textures.  Multiple stage firings will transform these materials as they combine and react with one another, leading to beautiful (and sometimes unexpected) results. Group analysis of these “surprises” will lead to further development and understanding of the techniques covered.

Students will create two wall pieces with heavily textured surfaces and aged, weathered effects, all inspired by textiles. Students will analyze firing results together, and emphasis will be placed on individual growth and development of designs and ideas, culminating in highly individual pieces.

Returning students are welcome to join Erna for this session.

In this class Erna will cover the basics of the drop-out technique for deep vessels while you also explore the chemically reactive combinations of glass and a variety of metals.

The results are vases or goblets, with smooth, glossy tops and sides, shapes that are usually only achieved by glass blowing.  You’ll go through the process from beginning to end:  the preparation of the blank while experimenting with a variety of materials that chemically react, the controlled drop out firing, the separation of the ‘collar’, as well as the grinding and polishing of the base and rim to produce a unique and nicely finished vessel.

The colour work focuses on the reactions which occur when specific glasses and metals are combined and the chemistry comes into play.

This is a field of experimentation without boundaries and you’ll learn which products are especially interesting and how you can playfully coax the glass to produce these fantastic effects.

Learn from Nathan Sandberg, the pioneer of the modern Vitrigraph methods in this intensive five-day workshop that debuts here at Vitrum Studio.

Nathan was very accustomed to making cane in the hot shop, and seven years ago he wanted to see if he could “make some cane” using the Vitrigraph kiln.  Looking back, those early results were discouraging compared to all that he has discovered is possible to create in this small kiln today.

 In this workshop Nathan will cover it all.  Kiln operation and set-up, stringer, how to specifically design cane and murine, and more will all be explained, demonstrated and put to use over the course of five days at his favorite studio in the country (his words).

  Aside from the basics, Nathan will also present his updated complex murrine methods, where thoughtful design and planning based on knowledge of how the glass moves as it exits the kiln comes into play.

Each student will leave the workshop with a finished project made using their own custom murrine as well as pulled cane/murrine they can use in future projects.

This workshop is for students of all skill levels. The only prerequisite is the ability to confidently and efficiently cut sheet glass.
