Stain (grey)
Grey (SnSb/SnSbV, SnSbV)
Additions of controlled quantities of vanadium oxide to the mixture before calcination produces a wide range of greys and chrome free brown suitable for all applications.
Colours containing vanadium must have freedom from soluble vanadium salts, minimizing the risks of producing dimples or other defects in the glazed surfaces of finished ware.
Color Range
-----------
Blue grey through neutral grey and brown grey to brown, the brownness of the shade increasing as the vanadium content increases.
Specific Gravity: 6.0 approximately.
Stability/Kiln Atmosphere
-------------------------
Excellent in all types of glazes and bodies for firing at temperatures up to 1300C. No tendency for colors to flash or separate. Must be fired in an oxidising or neutral atmosphere.
Compatibility
-------------
Suitable for blending with most other types of ceramic colors. Not suitable for blending with colors containing chrome oxide owing to the formation of chrome-tin pinks which show as brown discolorations.
Cost
----
Relatively high owing to the high intrinsic cost of tin oxide.
Note: This description is taken from information provided by Blythe Matthey and may or may not apply to stains of this family from other companies.
Suitable for most types of glazes for firing in an oxidizing atmosphere at temperatures up to 1300C.
Either zircon or tin oxide may be used as an opacifier.
Underglaze Color: Excellent for all applications that require neutral shade underglaze colours for firing in an oxidizing atmosphere at temperatures up to 1300C.
Chrome-free browns are possible.
Excellent in all types of bodies for firing in an oxidising atmosphere at temperatures up to 1300C.
Find wide applications as stains for bone china bodies.
Relative high cost of the colours is offset by their consistency and exceptional stability. Out Bound Links

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.
