High Temperature Fusing Techniques

When you take glass to 1700° F, it can get a little crazy. Glass doesn't just melt, it runs. And it doesn't just fuse, it flows. Strange, beautiful things can happen when you know the limits and how to push them. The result can be fantastic pieces of glass that can turn an average project into something truly spectacular.


In this exciting workshop, you will learn — and experience — the thrill of taking fusible glass to high temperatures (more than 200° above normal fusing levels) to create glass unlike any other. The class includes hands on learning for four different high temperature techniques:

Pot Melts: Also known as an aperature pour, this technique starts with a terra cotta pot carefully loaded with a deliberate arrangement of glass so that it runs through the hole in the bottom of the pot to create patterns that range in looks from delicate, tree-slice like lines to extraterrestrial storm systems!

Mesh Melts: If the single hole in a pot melt is able to create wonderous glass patterns, just imagine the results when the glass is melted through a screen-like mesh raised above the kiln shelf. At Helios, we've developed a unique approach that avoids both the cost of expensive metal screens and the spall (metal flaking) that often ruins otherwise beautiful glass melts. We'll take you through the whole process, from kiln setup to prepping the finished melt for use in a project.

Combing: Ask anyone who has ever combed (raked) hot glass and they will tell you how addicting it is to play with glass when it is hot, soft and pliable. We'll show you how to set up and fire the kiln and how to safely comb the glass at high temperatures.

High Fire: When glass reaches 1700° F, internal currents kick in and move glass in extreme and unexpected ways. We'll teach you how to set up dams for enough glass to create a thick slab of insanely swirled colors. You'll learn about colors that float, colors that won't tolerate the extreme heat, and much more.
