Beating Bubbles L072

Bubbles of trapped air are a perfectly natural phenomenon when working with kilnformed glass. Learn what causes large bubbles and ways to help prevent them

This lesson covers the causes of devitrification, ways to prevent it, and ways to deal with unintended devit if it develops.

Dealing with Devitrification L070

Devitrification, or devit, is the growth of crystalline structures on the surface of glass. Here, you will learn the causes of devitrification and ways to prevent it.

In this lesson, we'll focus on screen-printing studio practice, covering screen selection, needed chemicals, safety, set-up, printing, and cleaning.

Screen Printing: Screen Setup & Care L069

In this lesson, we'll focus on screen-printing studio practice, how to select an appropriate screen, what chemicals you'll need, and how to use them safely.

In this lesson, you'll learn how to make your own frit balls, with special firing considerations and ideas for using frit balls in many applications.

In this lesson, you'll learn how to make your own frit balls. We'll also discuss special firing considerations for different styles of glass, and ideas for using frit balls in a variety of kilnforming applications.

This lesson covers the characteristics of diamond hand laps, how to use them safely and effectively, and how they can be used before and after firings.

Coldworking with Diamond Hand Laps L064

Diamond hand laps are a powerful design tool available to kilnformers - learn to use them safely and effectively.

This lesson addresses the kinds of imagery best suited to this method, processes for preparing the image on vinyl, and how to transfer images to the screen.

Screen Printing with Hand-Cut Stencils L061

In this lesson, you will learn what kinds of imagery are best suited to the hand-cut stencil method, the process of preparing the image on vinyl, transferring it to the screen, and how to clean up materials when you're finished

This lesson teaches Stacy Lynn Smith's approach to powder printing—preferred tools, process steps and cleaning up.

Powder Printing L059

Powder printing allows artists to produce archival images on glass with a range of colors, textures, and layers of transparency. This lesson is based on Stacy Lynn Smith's approach to powder printing.

This lesson covers the unique visual properties of Opaline sheet glass, the science behind its color, and its effects when layered with other colored glass.

Expanding the Color Palette: Opaline Overlays L057

Opaline sheet glass has great potential to expand the color palette in kilnforming because it has the ability to create new colors with distinct properties. Learn more about using Opaline in this lesson.

This lesson combines 21 sheet glass styles to demonstrate how many custom colors you can make by combining hues from Bullseye's palette.

Expanding the Color Palette: Composite Colors L056

In this lesson, learn to create a broad array of hues for use in kiln-glass projects by firing two different colors of sheet glass together.

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 covers how to navigate design choices when working with thicker part sheets and how to minimize bubbles when working with bumpy part sheets.

Designing with Part Sheets, Part 2 L054

What should you expect when the part sheet is thicker than 3mm or if the surface is bumpy and irregular? Learn how to navigate these design choices in this lesson.

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.
