Change the composition of either and you get a differentįinish (or disaster if the mismatch is bad). It is formed by reaction between the powdered glost and the ceramicīody. The same as domestic glass but a vitrified or non-crystalline layer. So, if used whenĭescribing a glaze it would mean lustre or surface finish.Ī glaze is a thin layer of glass on a ceramic body. Indicate a surface finish or colouration. Livers of sulphur to cause a reaction that leaves a thin film of The Glass Caddy (#7151) is a great tool to keep it apart: just label one caddy "COE 90", and the other "COE 96.Patina is a term normally used to indicate a colour change due to If you are going to use glass with different COEs, plan ahead by creating separate storage areas for each one. Not to mention iridized and dichroic coatings, frit, confetti and stringers! In addition to the colors there's plenty of dazzling effects, including textures, streamers, feathers and streaks. Delphi offers hundreds of types of 90 CEO glass. Looking for a huge color palette? 90 COE glass has been used by glass artists for many years, resulting in an amazing selection of color that has been developed for fusers. Of course, these easy to work with properties also make it a favorite with many advanced artisans. 96 COE glass gets softer as it gets hotter, then it becomes more rigid as it cools, with a smooth progression and predictability. For your convenience you can print a firing log sheet from Delphi's Tips and Techniques web page.ĩ6 COE glass is excellent for beginners because it has a longer working range that provides more gradual heating changes. Many fusers keep track of test firing for easy reference. For instance, some glass colors "strike" (change color) when they are heated: Bullseye's Light Pink is pale lavender and strikes to a beautiful bright pink. This will help you predict any color shifts and ensure compatibility. Simply cut small pieces of the glass you plan to use in a project and fuse a test tile. Regardless of the COE you decide to work with, you will have an amazing selection of colors to use in your palette.Īn invaluable shortcut to getting the result you want is to make test firings. The main difference between the two is that 96 is generally softer and fuses at lower temperatures than 90. The two main COEs for fusible glass are 90 and 96. To avoid stress-cracks and breakage, it is very important to use glass that has the same COE. Fusible glass manufacturers test their glass to guarantee the COE (sometimes referred to as "tested-compatible"). To fuse multiple pieces of glass together, it's important to use glass that is compatible. in fused glass!Ī Coefficient of Expansion (COE) is simply a measurement of the rate that glass will expand and contract when it is heated and cooled. In our never-ending quest to "Make it Easy," our Delphi Experts have compiled the following pointers to help you make your next masterpiece. Any glass will melt in a kiln when you heat it up fusing glass successfully depends on knowing how different glasses work together.
