NotesMost often used to modify and soften the color of other metallic oxides and thus small amounts are normally employed.
It is not normally used in low fire glazes due to the refractory nature of nickel oxide powder. Glazes that are already matte or immature will thus be made more dry by the addition of nickel.
Since nickel is used in smaller amounts, flashing from other glazed ware and the chemistry of the glaze can have an effect on ware color.
Mechanisms
Glaze Color - Yellow In lithium glazes nickel can produce yellow. Glaze Color - Green In the presence of high MgO, nickel can produce greens. Zinc is also helpful to develop color. Glaze Color - Blue Nickel with zinc oxide can produce steel blues. With larger amounts of zinc, lavender blue can be made. Glaze Color - Tan Nickel with calcium can produce tan. Glaze Color - Brown Nickel with barium can produce brown. In high sodium glazes it can fire brown also. Glaze Color - Grey Nickel in lead glazes tends to produce grey colors. Glaze Color - Pink Nickel can produce pinks in high potash or lead glazes.

The future of ceramic recipe, material and physical testing record keeping is here.
Maintain your recipe database 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.
- Easy to import your existing data.
- As many side-by-side recipes as you want.
- Many ways to search and classify glaze and body recipes.
- Glaze and body recipes are robust, with units-of-measure, unlimited pictures with individual titles and descriptions.
- Add variations to a recipe; each with its own pictures, descriptions and name/code-number extensions.
- Recipes can link to 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 imports, and later search by batch.
- Assign multiple typecodes to imported glaze and body batches (to classify) and search on these later.
- Prepend character sequences to glaze recipe names during import.
- Import the pictures and pair them to their corresponding 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.
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.
