    -Some of the tools used for cutting glass include pliers or breakers, a glass cutter with a cutting wheel, running pliers, and mosaic cutters.

  • What is the importance of using fusible glass in glass fusing?

    -Fusible glass is important because it has the same coefficient of expansion (COE), allowing it to expand and contract at the same rate during the heating and cooling process without causing stress or breaking.

  • What does COE stand for in the context of glass?

    -COE stands for Coefficient of Expansion, which is a measure of how much a material expands or contracts with temperature changes.

  • What are the common COEs for glass used in fusing?

    -The most common COEs for glass used in fusing are 96 and 90, but they should not be mixed.

  • What are some different forms that glass can come in for fusing projects?

    -Glass can come in forms such as sheets, frit (crushed or ground glass), stringers, noodles, and powder.

  • Why is it recommended to wear a mask when working with powdered glass?

    -It is recommended to wear a mask when working with powdered glass to prevent inhaling the particulate matter, which can be harmful to the lungs.

  • What is the 'six millimeter rule' in glass fusing?

    -The 'six millimeter rule' refers to the tendency of glass to strive to be six millimeters thick during the fusing process, which is important for maintaining the shape and integrity of the glass design.

  • What is the purpose of using dams in glass fusing?

    -Dams are used to contain the glass and prevent it from spreading out beyond its original footprint during the fusing process, ensuring that the glass maintains its desired shape and thickness.

  • What is the process of slumping in glass fusing?

    -Slumping is the process of heating the glass to a slumping fuse temperature, which is cooler than a full fuse, allowing the glass to soften and take the shape of a mold, giving it a specific form or shape.

  • What kind of kits will Suzanne be putting together for glass fusing projects?

    -Suzanne will be putting together kits for creating items such as coasters, tiles, mini trays, dishes for tea bags or jewelry, decorative wall tiles, and a key holder.

  • How will the glass fusing kits be provided to participants?

    -The glass fusing kits can either be shipped to participants or picked up at the school, along with a video providing instructions on assembling the pieces and adhering them to the glass for firing.

🎨 Introduction to Glass Cutting and Fusing

Suzanne Balestri introduces herself as a kiln-formed glass artist and provides an overview of glass cutting techniques and qualities of glass important for fusing or kiln-forming. She demonstrates the use of tools such as pliers, glass breakers, a glass cutter, and mosaic cutters. Suzanne emphasizes the importance of using fusible glass with the same coefficient of expansion (COE) to avoid stress and potential breakage. She mentions the common COEs, 96 and 90, and introduces different forms of glass, including sheets, frit, stringers, noodles, and powder, while noting safety precautions when working with powdered glass.

πŸ“ Demonstration of Cutting Glass

The script describes a step-by-step demonstration of cutting a piece of glass using a glass cutter and a Morton board with a waffle grid system. Suzanne explains how to score the glass by creating a straight line and then breaking it cleanly using running pliers. She also discusses the use of mosaic cutters for creating small, irregular pieces of glass. Additionally, Suzanne introduces the 'six millimeter rule' in glass fusing, which states that glass naturally strives to be six millimeters thick, affecting how layered glass behaves during the fusing process.

🌑 Understanding the Six Millimeter Rule in Glass Fusing

Suzanne elaborates on the 'six millimeter rule,' explaining how glass behaves when heated in a kiln, spreading out to achieve a thickness of about a quarter of an inch unless contained by dams. She illustrates the concept with examples of how single layers of glass contract to achieve the desired thickness, leading to a 'dog boning' effect, while multiple layers maintain a flatter surface. The demonstration includes the use of kiln bricks as dams to contain the glass during the fusing process.

πŸ”₯ Post-Fusing Process and Slumping Glass

After discussing the fusing process and the importance of temperature control for different thicknesses of glass, Suzanne describes the process of slumping glass into a mold after the initial firing. She explains that the glass is cut to fit the mold and fired at a slumping temperature, which is cooler than a full fuse, allowing the glass to soften and take the shape of the mold. The script concludes with Suzanne's plans to offer fusing kits for creating items like coasters, tiles, and decorative wall pieces, which can be shipped or picked up and include instructions for assembly and firing in her home studio.

Keywords
πŸ’‘Fused Glass
Fused glass refers to the process of melting glass in a kiln to join pieces together without the use of a kiln or external adhesive. In the video, Suzanne Balestri demonstrates various techniques and considerations for working with fused glass, emphasizing the importance of using fusible glass and ensuring all pieces have the same Coefficient of Expansion (COE) to prevent stress and breakage.
πŸ’‘Kiln-Forming
Kiln-forming is a glass art technique where pieces of glass are heated in a kiln to a specific temperature to achieve a desired shape or form. The script mentions kiln-forming in the context of fusing glass pieces together and shaping them using molds after the initial firing process.
πŸ’‘Glass Cutter
A glass cutter is a tool used to score and cut glass along a straight line. In the video, Suzanne uses a glass cutter with a small cutting wheel to demonstrate how to score glass before breaking it along the scored line using pliers.
πŸ’‘Coefficient of Expansion (COE)
The Coefficient of Expansion (COE) is a measure of how much a material expands or contracts with changes in temperature. In the context of the video, Suzanne explains that all glass pieces used in a fused glass project must have the same COE to ensure they expand and contract uniformly during the firing process, preventing stress and potential breakage.
πŸ’‘Mosaic Cutters
Mosaic cutters are specialized tools used for cutting glass into small, irregular shapes for use in mosaic art. Suzanne mentions mosaic cutters as one of the tools she uses and demonstrates how they can be used to create random-sized pieces of glass for unique designs.
πŸ’‘Glass Frit
Glass frit refers to crushed or ground glass, which comes in various granular sizes. In the video, Suzanne discusses different forms of glass, including frit, and how medium frit can be seen in a fired sample tile, demonstrating its appearance when incorporated into a fused glass piece.
πŸ’‘Stringers and Noodles
Stringers and noodles are thin, elongated forms of glass that can be used to create intricate designs in fused glass art. Suzanne provides examples of how stringers and noodles can be applied to a glass piece and how they transform after being fired in the kiln.
πŸ’‘Six Millimeter Rule
The 'six millimeter rule' is a concept in glass fusing that states glass tends to spread out during the firing process to achieve a thickness of approximately six millimeters. Suzanne explains this phenomenon and its implications for design, such as the need for dams to contain glass and prevent the 'dog boning' effect where glass pulls in at the center due to uneven thickness.
πŸ’‘Dams
Dams are kiln bricks or other containment structures used in glass fusing to control the spread of glass layers during the firing process. Suzanne mentions using dams to prevent the glass from spreading out beyond the desired thickness and to maintain the shape and size of the design.
πŸ’‘Slumping
Slumping is the process of shaping glass over a mold after it has been fused but before it has fully cooled. Suzanne describes slumping as a technique to give glass a specific shape, such as a dish or a bowl, by heating it to a slumping temperature in the kiln where it softens and conforms to the mold's shape.
πŸ’‘Frit
Frit is a granular form of glass that can be used in various sizes, from fine (like sugar or sand) to coarse (larger granules) and even powder. Suzanne explains the use of frit in glass fusing, including the need for a mask when working with powdered glass to prevent inhalation of the fine particles.
