Topic Annealing

Skillful kilnforming usually requires savvy annealing. This lesson explores the many considerations involved in successful annealing of Bullseye Glass.

Recommended Annealing Cycle for Bullseye Glass L206

This 20-minute presentation focuses on the theory and process of getting the stress out of fused glass work and acts as an introduction to the new annealing cycle recommended by Bullseye.

This lesson covers strategies for working with multiple firings, the cumulative effect of heatwork on glass, and how to anneal works fired multiple times.

Considerations for Multiple Firings L130

Here, we cover strategies for successfully reheating pre-fired work, the cumulative effect of heatwork on glass, how to anneal works that have been fired multiple times, as well as some special considerations.

In this lesson, you'll learn about design, setup, and firing considerations for kilncarving billets. We’ll also cover some variations on the technique.

Kilncarved Billet L121

In this lesson, you'll learn about design, setup, and firing considerations for kilncarving billets, as well as some variations.

In this lesson, we make a thick slab of glass for a small tabletop, covering how to calculate glass volume, make containment walls, and fire your piece.

Tabletops L083

In this lesson, we'll use a similar method to "Working Deep", making a thick slab of glass for a small tabletop with a combination of sheet glass and billets for rapid assembly.

Lost Wax Kilncasting L074

In this lesson you will learn how to prepare a wax model, how to make a two-layered refractory mold, how to steam the wax out of the mold, and successfully cool and clean the piece.

Box casting allows makers to create a reverse-relief, cast-glass object of exceptional clarity, using an alginate mold and a vermiculite box.

Box Casting L055

Box casting is a great way to create a reverse-relief, cast-glass object with exceptional clarity. This process is ideal for producing multiple editions of a piece.

This lesson demonstrates how to create individual design layers, how to control bubbles and minimize coldworking, and how to fire and finish the work.

Working Deep L053

In this lesson you will learn how to create individual design layers, lay up a block to control bubbles and minimize coldworking, and considerations for damming, firing, and finishing the work.

In this lesson, learn some of the ways that harnessing glass flow can help you achieve spectacular effects with your glass.

Harnessing Flow in Kiln-Glass L048

In this lesson you will learn how glass flow can be controlled to spectacular effect.

This lesson explores two of the most important practices for avoiding unwanted breaking: avoiding thermal shock and ensuring proper annealing.

Why Did It Break? L042

This lesson covers two of the most common causes of a piece breaking: thermal shock and improper annealing.

This lesson demonstrates on-edge strip construction's methods for cutting and composing with strips, firing and finishing work, and adding special effects.

On-Edge Strip Construction L033

In this lesson you will learn tips for cutting and composing with glass strips, as well as some special effects you can achieve with on-edge construction.

This lesson provides instructions for making a thick-walled kilnformed glass container. It explores the materials, tools, and techniques involved.

Kilnformed Container L028

This lesson provides basic instructions for making a thick-walled kilnformed glass container.

This lesson covers methods for open-faced kilncasting, including preparing the model, making an open-faced mold, and calculating the needed glass volume.

Open-Faced Kilncasting L026

In this lesson, you will learn considerations for preparing a model, tips for making an open-faced mold and calculating the amount of glass needed to fill it.
