Kansas Clay - Cone 06-04 Earthenware White Plus

$27.30
Maximum quantity available reached.
Sku: Earthenware White Plus-25
Product Description

A general purpose low-fire white clay with approximately 9% fine silica sand for electric kiln firing. Fires very white. Shows glazes well.


During the summer of 2020, Kansas Clay completed a comprehensive test of their clay bodies.  For each clay body, they tested 6 flat bars, which were rolled out on a slabroller.  They ALSO tested vertical shrinkage of a thrown cylinder (6 sections, each with their own test).

Flat Vertical
Wet to Dry Shrinkage 2.33% 1.75%
Overall Shrinkage 4.65% 4.37%
Absorption 9.87%
LOI 11.2%

 

Testing Methodology

  • Beginning weights in grams were recorded
  • Lines and weights were measured & recorded when bone dry
  • The samples were fired to Cone 04
  • Lines and weights were measured & recorded again
  • The flat tiles were then soaked in hot water for 1 1/2 hours, then weighed again
  • Math magic was then done to calculate the average shrinkage wet-dry and average shrinkage overall for both flat and thrown tests, and the average water absorption was calculated based on the flat bars.
  • We also figured the "LOI" (Loss on Ignition) by computing the fired weight against the bone dry weight.  This tells us what percent of organics burn off in the firing.    
Flint Hills clays have been evaluated by a nationally certified toxicologist, and have been found to be in compliance with ASTM C-1023 and D-4236, and to not contain any material in sufficient quantity to be toxic or to constitute a chronic health hazard when used responsibly.
