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.

Acid Solubles: 2-4
pH: 9.5
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.
