B Clay
Buff Firing Stoneware Clay
High temperature clean buff firing stoneware clay mined at Ravenscrag, Sask.
Analysis updated July 97.
There is some argument whether the mineralogy should be muscovite or illite. Here is the comment of one technician: "With regards to illite or muscovite, the only way to categorically
differentiate between the two is to determine the layer charge (most easily by electron microscopy) which I didn't do. In this sample, the mica component has no detectable expandability which suggests a high charge mica with very little depotassification typical of muscovites. Also, the x-ray scattering domain size is quite large with minimal disorder which you seldom find in illite but expected for muscovite. However, the kaolinite in the sample is extremely fine as one would see in fireclays. 41% quartz in the sample is accurate. You can easily verify this from your chemistry by checking the contributions of muscovite, kaolinite, smectite and K-spar to the total SiO2, and constraining potassium to
muscovite and K-spar, and Mg to smectite. From my experience, a high plasticity and the apparent illitic properties that you see in the clay is most likely due to the discrete smectite content (8%). Note that the activity of smectite is several orders of magnitude (up to 10 times) greater than the finest kaolinite or illite."

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.
