There is a close link between the way glazes fire in a kiln and their chemistry. Physical properties like color, hardness, melting temperature, thermal expansion, leachability, etc are all direct products of the chemistry. Understanding the relationship between the absolute and relative amounts of the common oxides appearing in a typical glaze formula (not a recipe) to the physical presence of a fired glaze itself is the key to control. An education in glaze chemistry usually starts with a study of each of the dozen or so oxides that a fired glaze is conceptually structured from and what properties each contributes; then a study of what materials contribute what oxides and finally how to use a computer program to study existing glazes and explain their behavior and start adjusting them to alter properties or fix problems. Understanding this is well within the reach of anyone and is actually much simpler than trying to grasp the relationship between the recipe of a glaze and its behavior.

The future of ceramic recipe, material and physical testing record keeping is here. Just pennies a day.
Maintain your recipes and materials on-line
- Login to a private account or work with others in a group account (e.g. university).
- Nothing to install (access it using your web browser). It is always the latest version.
- Import existing material, recipe data.
- As many side-by-side recipes and/or materials as you want (chemistry is shown for all).
- Many ways to search and classify glaze and body recipes.
- Glaze and body recipes are robust, with units-of-measure, pictures with individual titles and descriptions, material links.
- Add variations to a recipe; each with its own pictures, descriptions and name/code-number extensions.
- Recipes can link to materials, typecodes, projects and firing schedules (all managed in their own areas).
- Standard reports and mix ticket reports with last-minute-totalling; variations report as if they are a complete recipe.
- Video tutorials, help system, contact form on every page, dedicated messaging and support ticket systems.
- It is an industrial-strength database system (unlimited capacity, fast, reliable, scalable).
Imports many file formats
- Glaze recipe formats supported: HyperGlaze, GlazeGhem, GlazeMaster, Matrix, INSIGHT XML recipes (single and multiple), INSIGHT SQLite DB files.
- Assign a batch number to recipe imports (later search by batch).
- Assign multiple typecodes to imported glaze and body batches (to classify) (search on these later).
- Prepend character sequences to glaze recipe names during import.
- Import the pictures and pair them to their corresponding recipe records automatically.
- One click to automatically export the database to an SQLite DB database file and download it (for use with desktop INSIGHT or just as a backup).
- Export and import individual glaze recipes as text or XML.
- Import materials data in various formats or just use the thousands of built-in reference materials.
Perfect for Education
- Ceramic study programs can now accumulate material, recipe and testing data year-after-year, students can login and together build a valuable ceramic glaze and body knowledge resource.
- Students already have internet connected devices, computers are not even needed in the class.
- The Reference Manager gives you quick access to the Digitalfire Ceramic Reference Database.
