Modeling Glass


SKU: Modeling Glass Categories: , ,


The Starter Kit contains one 3.5-ounce jar of powdered binder and one 2-ounce bottle of liquid medium, plus an instruction sheet. This kit can be mixed with glass powder to make over 3 pounds of Modeling Glass.

Additional Modeling Glass refills are available in larger sizes:  4-ounce bottles of Liquid Medium and 7-ounce jars of Powdered Binder. These are sold individually, you will need to buy both the medium and the binder to have what you need to make modeling glass or buy the starter package that includes both.

Attention: The mixing instructions for Modeling Glass were developed for use with Bullseye Glass powders. The ratio for mixing Modeling Glass with Spectrum/Uroboros or other powders is slightly different. INCREASE BINDER from 2 1/2 level teaspoons (6g) to 1 level tablespoon (7g). INCREASE WATER from 1/4 cup plus 2 teaspoons (60g) to 1/4 cup plus 2 1/4 teaspoons (70g). That’s it!

How does Modeling Glass Work?

You can turn glass powder into a moldable, sculptable material similar to clay using the two-part Modeling Glass Starter Kit. The Powdered Binder is a food-grade, nontoxic cellulose-based material that reacts with water as a thickener. The Liquid Medium is also food-grade and nontoxic and combines with water to give body and smoothness to the Modeling Glass, while preventing stickiness. Both the Binder and the Liquid Medium burn away during firing, leaving pure glass behind. There is approximately a 15% shrinkage.


LOIS MANNO (The Artist & Creator)

I’ve been an artist most of my life, working in pastel, acrylic, scratchboard, watercolor, etc. and as a professional freelance designer. But when I tried glass for the first time about 7 years ago, it was life-changing. My first workshop was about “painting” with frit, and I loved working with the powders, as the effect was similar to pastel in some ways. What I didn’t like was the mess and lost powder. I’m thrifty and a control freak, and seeing all that powder sifting around made me crazy. What, I wondered, would happen if I mixed powdered glass with a binder of some sort? Could I get that powder under control?


At the time I was such a newbie I knew almost nothing about things like pate de verre (except that it is beautiful), and my exposure to other techniques was minimal. In a way, my ignorance freed me up to experiment, as I didn’t really know what wasn’t possible. I started doing research online about other ingredients that have been added to glass over the years, and I put my own twist on it, experimenting with different combinations, and adding a liquid medium of my own formulation.


Once I perfected the mixture, I was able to make a material very much like modeling clay, that could be used to make 3-dimensional shapes without the need for complicated mold-making (did I mention that I’m both a control freak and into instant gratification?). Thus, Modeling Glass was born.

Now I’m teaching my process of making glass feathers using Modeling Glass, and am excited to see what other artists will be able to make with Modeling Glass!
