Pioneer 2661 Talc
White Texas Talc
Now called AmTalc
Texas Talc has a darker grey raw color and a rounder fluffier particle than other talcs. However it fires very white and is desired for its consistency. It is commonly used in ceramic slurries for low temperature greenware. Pioneer talcs are non-asbestiform.
Various grades are available.

LOI: 11.5
Water Solubles: -.1
Dry Brightness: 58-65
Dry Brightness after firing: 88+
Specific gravity: 2.7
Tapped Density: 75-85 lbs/ft3
Loose Density: 35-45 "
One Lb. Bulks, Gallons: .04
Shrinkage: 0.60
Oil Absorption: 32
Hegman Fineness: 1.0
Thru 200 mesh, %: 97.0
Thru 325 mesh, %: 85.0
Median Particle Size: 19.0 microns
2882 Talc is the same except:
Fe2O3: < .69
Dry Brightness: 62.0
Pioneer 1599 is a platy Texas general purpose industrial talc.

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.
